Opis:

This article provides an overview of the existing problems in the construction of wireless sensor networks (WSN), in particular the problem of energy efficiency of the system. In many cases, the WSN is set in places where the connection to the stationary power sources is difficult or impossible. Such situations require the use of autonomous energy sources: traditional (batteries) or alternative (solar panels, wind generators, etc.). Due to limitations in the available system power there is obvious need in efficient use of available energy resources.

Opis:

The performance and efficiency of a Wireless Sensor Network (WSN) is typically subject to techniques used in data routing, clustering, and localization. Being primarily driven by resource constraints, a Socionomic model has been formulated to optimize resource usage and boost collaboration among sensor nodes. In this paper, we present several experimental results to ascertain the underlying philosophy of the Socionomic model for improving network lifetime of resource constrained devices - such as, sensor nodes.

Opis:

Many applications of wireless sensor networks (WSN) require information about the geographical location of each sensor node. Self-organization and localization capabilities are one of the most important requirements in sensor networks. This paper provides an overview of centralized distance-based algorithms for estimating the positions of nodes in a sensor network. We discuss and compare three approaches: semidefinite programming, simulated annealing and two-phase stochastic optimization-a hybrid scheme that we have proposed. We analyze the properties of all listed methods and report the results of numerical tests. Particular attention is paid to our technique-the two-phase method-that uses a combination of trilateration, and stochastic optimization for performing sensor localization. We describe its performance in the case of centralized and distributed implementations.

Opis:

An original wireless sensor network for vibration measurements was designed. Its primary purpose is modal analysis of vibrations of large structures. A number of experiments have been performed to evaluate the system, with special emphasis on the influence of different effects on simultaneity of data acquired from remote nodes, which is essential for modal analysis. One of the issues is that quartz crystal oscillators, which provide time reading on the devices, are optimized for use in the room temperature and exhibit significant frequency variations if operated outside the 20–30°C range. Although much research was performed to optimize algorithms of synchronization in wireless networks, the subject of temperature fluctuations was not investigated and discussed in proportion to its significance. This paper describes methods used to evaluate data simultaneity and some algorithms suitable for its improvement in small to intermediate size ad-hoc wireless sensor networks exposed to varying temperatures often present in on-site civil engineering measurements.

Opis:

Wireless sensor network localization is a complex problem that can be solved using different types of methods and algorithms. Nowadays, it is a popular research topic. What becomes obvious is that there are several criteria which are essential when we consider wireless sensor networks. Our objective is to determine accurate estimates of nodes location under the constraints for hardware cost, energy consumption and computation capabilities. In this paper the application of stochastic optimization for performing localization of nodes is discussed. We describe two phase scheme that uses a combination of the trilateration method, along with the simulated annealing optimization algorithm. We investigate two variants of our technique, i.e., centralized and distributed. The attention is paid to the convergence of our algorithm for different network topologies and trade-off between its efficiency and localization accuracy.

Opis:

Wireless sensor networks (WSNs) are usually a resource constrained networks which have limited energy, bandwidth, processing power, memory etc. These networks are now part of Internet by the name Internet of Things (IoT). To get many services from WSNs, we may need to run many applications in the sensor nodes which consumes resources. Ideally, the resources availability of all sensor nodes should be known to the sink before it requests for any further service(s) from the sensor node(s). Hence, continuous monitoring of the resources of the sensor nodes by the sink is essential. The proposed work is a framework for monitoring certain important resources of sensor network using Adaptive-Neuro Fuzzy Inference System (ANFIS) and Constrained Application Protocol (CoAP). The ANFIS is trained with these resources consumption patterns. The input to ANFIS is the resources consumption levels and the output is the resources consumed levels that needs to be sent to the sink which may be individual or combinations of resources. The trained ANFIS generates the output periodically which determines resources consumption levels that needs to be sent to the sink. Also, ANFIS continuously learns using hybrid learning algorithm (which is basically a combination of back propagation and least squares method) and updates its parameters for better results. The CoAP protocol with its observe option is used to transport the resource monitoring data from the sensor nodes to the cluster head, then from the cluster head to the sink. The sensor nodes runs coap server, the cluster head runs both coap client and server and the sink runs coap client. The performance of the proposed work is compared with LoWPAN network management protocol (LNMP) and EmNets Network Management Protocol (EMP) in terms of bandwidth and energy overheads. It is observed that proposed work performs better when compared to the existing works.

W artykule przedstawiono metodę zrównoważenia zużycia energii w bezprzewodowej sieci pomiarowej. W przypadku rozwiązań bezprzewodowych istotnymi aspektami są zużycie energii oraz zrównoważenie zużycia energii. Opisano metody i wyniki symulacji pracy sieci przy klasycznym rozwiązaniu oraz przy zastosowaniu opracowanej metody. Wykazano czterokrotne zmniejszenie rozrzutu energii w sieci przy niewielkim wzroście łącznego zużycia energii. Opracowane rozwiązanie jest testowane na prototypowej sieci pomiarowej.
In this paper there is described the routing algorithm for wireless sensor networks. Energy consumption is very important for self-powered radio nodes. But in some applications energy balancing is more important. Wireless sensor networks used in large areas like farmlands or warehouses consist of hundreds of nodes. In classic methods routing is directed to short time of transmission or low energy consumption. But unbalanced energy consumption can often cause unpredictable failures because of lack of energy in frequently used nodes. Energy balancing prevents this behavior by dynamic bypassing the used nodes. The paper presents five methods for reducing energy consumption and a new method for energy balanced routing. The advantages and disadvantages of the methods are de-scribed. Fig. 1 shows the algorithm diagram. The performed simulations show almost four times smaller energy consumption deviation than the deviation in classic routing method. The energy balancing can be improved by changing the sequence of transmis-sion.

Opis:

Over the last few years, wireless sensor networks (WSNs) have started to play more and more important role in civil and military applications. A typical sensor network consists of resource-constrained sensing nodes, which monitor environment and send the data to more powerful gateway nodes. The goal of gateway nodes is to aggregate, process and send the data to other gateways or directly to sink nodes. The proper placement of nodes is needed to provide good network operation. Sensing nodes are often placed in a random manner unlike gateways. Gateways, due to their role and cost, are installed rather in a controlled way. In this paper, a bi-criteria gateway placement problem is introduced. The problem is shown to be NP-hard. We formulate it as a linear programming problem, then we develop the Multi-criteria Simulated Allocation (MSAL) heuristic algorithm, for the purpose of cost-effective gateway deployment and power-effective wireless connection management. Finally, we evaluate the efficiency of the algorithm by comparison with the exact method.

Opis:

The failure rate of sensor nodes in Heterogeneous Wireless Sensor Networks is high due to the use of low battery-powered sensor nodes in a hostile environment. Networks of this kind become non-operational and turn into disjoint segmented networks due to large-scale failures of sensor nodes. This may require the placement of additional highpower relay nodes. In this paper, we propose a network partition recovery solution called Grey Wolf, which is an optimizer algorithm for repairing segmented heterogeneous wireless sensor networks. The proposed solution provides not only strong bi-connectivity in the damaged area, but also distributes traffic load among the multiple deployed nodes to enhance the repaired network’s lifetime. The experiment results show that the Grey Wolf algorithm offers a considerable performance advantage over other state-of-the-art approaches.

Opis:

Wireless Sensor networks are widely adopt in military, target tracking, signal processing and monitoring applications like traffic and structural, the small and low cost unreliable sensor nodes in these applications uses batteries as the sole energy source. The energy efficiency becomes difficult task as the tiny and less weight battery act as source of each node. Scheduling the different category of data packets is a way to reduce the power consumption and increasing the lifetime of sensor nodes. The existing scheduling algorithms are not adapted to the environment changes. The basic FCFS (First Come First Serve) suffered by long delay while transmit the real time data packets. In DMP (Dynamic Multilevel Priority) real time data packets occupies highest priority, the remaining non real time data packets sent to lower priority level queues. Some real time task holds the resources for longer time, the other task have to wait, it makes the deadlock condition. The NJN (Nearest Job Next) will select the nearest requesting sensor node for service, real time packets have to wait long time. The proposed Adaptive weighted scheduling scheme changes the behavior of the network queue by adaptively changes the weights based on network traffic. Simulation results proof that, adaptive weighted scheduling algorithm works better than the FCFS and DMP data scheduling in terms of energy consumption and lifetime. Our future scheme to integrate Internet of Things (IoT) with the WSN to increase the performance of the wireless networks.

On the other hand, more and more application scenarios require sensor nodes to be mobile, which imposes new technological challenges for security. Key management is the core for secure data communications among the resource-constrained sensor nodes. In this paper, based on the Group Diffie-Hellman key agreement protocols and the energy level of each node in the network, we propose Energy Aware Group Diffie-Hellman key management protocol for mobile wireless sensor networks. The simulation results show that the proposed key management protocol provide significant improvement in maximizing the lifetime of networks.

Wireless sensor networks can be used by the military for a number of purposes such as monitoring militant activity in remote areas and force protection. Being equipped with appropriate sensors these networks can enable detection of enemy movement, identification of enemy force and analysis of their movement and progress. The focus of this article is on the military requirements for flexible wireless sensor networks. Based on the main networking characteristics and military use-cases, insight into specific military requirements is given in order to facilitate the reader's understanding of the operation of these networks in the near to medium term (within the next three to eight years). The article structures the evolution of military sensor networking devices by identifying three generations of sensors along with their capabilities. Existing developer solutions are presented and an overview of some existing tailored products for the military environment is given. The article concludes with an analysis of outstanding engineering and scientific challenges in order to achieve fully flexible, security proved, ad hoc, self-organizing and scalable military sensor networks.

Opis:

Many applications of wireless sensor networks (WSN) require information about the geographic location of each sensor node. Devices that form WSN are expected to be remotely deployed in large numbers in a sensing field, and to self-organize to perform sensing and acting task. The goal of localization is to assign geographic coordinates to each device with unknown position in the deployment area. Recently, the popular strategy is to apply optimization algorithms to solve the localization problem. In this paper, we address issues associated with the application of heuristic techniques to accurate localization of nodes in a WSN system. We survey and discuss the location systems based on simulated annealing, genetic algorithms and evolutionary strategies. Finally, we describe and evaluate our methods that combine trilateration and heuristic optimization.

Opis:

The below work is done to address the things like how fast can information be collected from a wireless sensor network organized as tree using realistic simulation models under the many-to-one communication paradigm known as converge cast. We first consider time scheduling on a single frequency channel with the aim of minimizing the number of time slots required to complete a converge cast. Next, we combine scheduling with transmission power control to mitigate the effects of interference, and show that while power control helps in reducing the schedule length under a single frequency, scheduling transmissions using multiple frequencies is more efficient. To this end, we construct degree-constrained spanning trees and capacitated minimal spanning trees, and show significant improvement in scheduling performance over different deployment densities. Lastly, we evaluate the impact of different interference and channel models on the schedule length.

The major challenge in designing wireless sensor networks (WSNs) is to find tradeoff between the desired and contrary requirements for the lifetime, coverage or cost while coping with the computation, energy and communication constraints. This paper examines the optimal placement of nodes for a WSN. It is impossible to consider the deployment of the nodes separately from WSNs applications. We highlight the properties of WSNs applications that determine the placement problem. We identify and enumerate the various objectives that should be considered. The paper provides an overview and concentrates on multi-objective strategies, their assumptions, optimization problem formulation and results.

Opis:

Due to the severe damages of nuclear accidents, there is still an urgent need to develop efficient radiation detection wireless sensor networks (RDWSNs) that precisely monitor irregular radioactivity. It should take actions that mitigate the severe costs of accidental radiation leakage, especially around nuclear sites that are the primary sources of electric power and many health and industrial applications. Recently, leveraging machine learning (ML) algorithms to RDWSNs is a promising solution due to its several pros, such as online learning and self-decision making. This paper addresses novel and efficient ML-based RDWSNs that utilize millimeter waves (mmWaves) to meet future network requirements. Specifically, we leverage an online learning multi-armed bandit (MAB) algorithm called Thomson sampling (TS) to a 5G enabled RDWSN to efficiently forward the measured radiation levels of the distributed radiation sensors within the monitoring area. The utilized sensor nodes are lightweight smart radiation sensors that are mounted on mobile devices and measure radiation levels using software applications installed in these mobiles. Moreover, a battery aware TS (BATS) algorithm is proposed to efficiently forward the sensed radiation levels to the fusion decision center. BA-TS reflects the remaining battery of each mobile device to prolong the network lifetime. Simulation results ensure the proposed BA-TS algorithm’s efficiency regards throughput and network lifetime over TS and exhaustive search method.

The recent decades have seen the growth in the fields of wireless communication technologies, which has made it possible to produce components with a rational cost of a few cubic millimeters of volume, called sensors. The collaboration of many of these wireless sensors with a basic base station gives birth to a network of wireless sensors. The latter faces numerous problems related to application requirements and the inadequate abilities of sensor nodes, particularly in terms of energy. In order to integrate the different models describing the characteristics of the nodes of a WSN, this paper presents the topological organization strategies to structure its communication. For large networks, partitioning into sub-networks (clusters) is a technique used to reduce consumption, improve network stability and facilitate scalability.

Opis:

This paper aims at designing, building, and simulating a secured routing protocol to defend against packet dropping attacks in mobile WSNs (MWSNs). This research addresses the gap in the literature by proposing Configurable Secured Adaptive Routing Protocol (CSARP). CSARP has four levels of protection to allow suitability for different types of network applications. The protocol allows the network admin to configure the required protection level and the ratio of cluster heads to all nodes. The protocol has an adaptive feature, which allows for better protection and preventing the spread of the threats in the network. The conducted CSARP simulations with different conditions showed the ability of CSARP to identify all malicious nodes and remove them from the network. CSARP provided more than 99.97% packets delivery rate with 0% data packet loss in the existence of 3 malicious nodes in comparison with 3.17% data packet loss without using CSARP. When compared with LEACH, CSARP showed an improvement in extending the lifetime of the network by up to 39.5%. The proposed protocol has proven to be better than the available security solutions in terms of configurability, adaptability, optimization for MWSNs, energy consumption optimization, and the suitability for different MWSNs applications and conditions.

Opis:

Recent advances in technology have enabled the development of low cost, low power and multi functional wireless sensing devices. These devices are networked through setting up a Wireless Sensor Network (WSN). Sensors that form a WSN are expected to be remotely deployed in large numbers and to self-organize to perform distributed sensing and acting tasks. WSNs are growing rapidly in both size and complexity, and it is becoming increasingly difficult to develop and investigate such large and complex systems. In this paper we provide a brief introduction to WSN applications, i.e., properties, limitations and basic issues related to WSN design and development. We focus on an important aspect of the design: accurate localization of devices that form the network. The paper presents an overview of localization strategies and attempts to classify different techniques. A set of properties by which localization systems are evaluated are examined. We then describe a number of existing localization systems, and discuss the results of performance evaluation of some of them through simulation and experiments using a testbed implementation.

Opis:

Multi-hop networks, such as WSNs, become an object of increasing attention as an emerging technology which plays an important role for practical IoT applications. These multi-hop networks generally consist of mobile and small terminals with limited resources, which makes them vulnerable to various network status changes. Moreover, the limited nature of terminal resources available, especially in terms of battery capacity, is one of the most important issues to be addressed in order to prolong their operating time. In order to ensure efficient communications in such networks, much research has already been conducted, especially in the field of routing and transmission technologies. However, conventional approaches adopted in the routing field still suffer from the so-called energy hole problem, usually caused by unbalanced communication loads existing due to difficulties in adaptive route management. To address this issue, the present paper proposes a novel routing algorithm that utilizes ACO-inspired routing based on residual energy of terminals. Operational evaluation reveals its potential to ensure balanced energy consumption and to boost network performance.

In this case, we have to use sensor to monitor the patient activities without manual support. By using eye blink sensor, motion sensor and temperature sensor to check the level of patient and it will be displayed in LCD. If some abnormalities occur, we have to give alarm by using buzzer to caregiver, doctor or family members. We have to use ZigBee, for storing the patient details in the hospital management. It is useful to check the patient report with secure level in the database.

The framework simulates operation of a sensor network with data transmission, which enables simultaneous development of the sensor network software, its hardware and the protocols for wireless data transmission. An advantage of using the framework is converging simulation with the real software. Instead of creating a model of the sensor network node, the same software is used in real sensor network nodes and in the simulation framework. Operation of the framework is illustrated with examples of simulations of selected transactions in the sensor network.

In this paper a summary is given of the ongoing research at the Belgian Royal Military Academy in the field of mobile ad hoc networks in general and wireless sensor networks (WSNs) in particular. In this study, all wireless sensor networks are based on the physical and the medium access layer of the IEEE 802.15.4 low rate wireless personal area networks standard. The paper gives a short overview of the IEEE 802.15.4 standard in the beaconless mode together with a description of the sensor nodes and the software used throughout this work. The paper also reports on the development of a packet sniffer for IEEE 802.15.4 integrated in wireshark. This packet sniffer turns out to be indispensable for debugging purposes. In view of future applications on the wireless network, we made a theoretical study of the effective data capacity and compared this with measurements performed on a real sensor network. The differences between measurements and theory are explained. In case of geograph- ically meaningful sensor data, it is important to have a knowledge of the relative position of each node. In the last part of the paper we present some experimental results of positioning based on the received signal strength indicators (RSSI). As one could expect, the accuracy of such a method is poor, even in a well controlled environment. But the method has some potential.

The network lifetime can be enhanced with the help of Multi-Layer protocol (ML-MAC). This paper presents a practical approach including 3-dimensional deployment of sensor nodes and analyzes two different types of networks – homogeneous and heterogeneous WSNs. To analyze various QoS parameters, two types of nodes are considered in a heterogeneous network. The performance of both the networks is compared through simulations. The results show that ML-MAC performs better for a 3D heterogeneous WSNs.

The article presents a new dfferentiated service modelsupported (DSM) cluster-based routing in wireless sensor networks (WSNs) that overcomes the above issue. DSM prioritizes the transfer of dfferent flow types based on packet type and packet size. The employment of computational offlading minimizes delay for critical and small-sized data packets and by carrying out data reduction of large-sized packets at proxy server. It outperforms the existing protocols in terms of energy efficiency, throughput, and reliability by prioritizing the transfer of time-critical health application data.

Opis:

Recently, forest fire monitoring system in wireless sensor networks has received much attention. The conventional scheme receives fire alert data quickly to inform about fire forest event. However, since two or more nodes may detect a fire, high priority fire detection data frequently collide. In this paper, a new forest fire monitoring system is proposed in order to reduce high priority fire detection data dropped rate, by specifying a high priority received data immediately after fire detection and just before the destruction by fire. Furthermore, the node only transmits high priority data to a node, which has a low possibility of destruction by fire for low end-to-end delay of high priority fire detection data. The simulation results show that proposed scheme can reduce high priority data dropped ratio and the end-to-end delay, and have less effect of wind direction compared with the conventional scheme.

Considering the related studies on transport protocols, which are mostly dedicated to a single-direction reliable data transport, RBCP is the answer for the lack of control mechanisms in WSNs based on bidirectional communication. The first part of this paper is focused on general presentation of the proposed solution. In the next part, evaluation of the idea and final functionality are discussed. It will finally show the results of undergone testing stage.

A new method of lossless Secure Data Aggregation for Wireless Sensor Network is presented. Secure Data Aggregation is achieved using the popular Chinese Remainder theorem. Here, an ‘Augmented Chinese Remainder System’ is introduced that incorporates additional features to enforce a higher level of security to the aggregated data. The scheme provides inbuilt signature verification and eliminates the need for separate data validation algorithms. The method achieves data integrity and authentication simultaneously in addition to lossless data aggregation for the data forwarded from the Cluster Head to the Base Station. The aggregate contains the entire individual data from sensors in the encrypted form and the receiver deaggregates it to get the original data in full without any loss. The Augmented Chinese Remainder System can be extended to secure Multi-level Data Aggregation for WSN.

Opis:

Thousands of low-power micro sensors make up Wireless Sensor Networks, and its principal role is to detect and report specified events to a base station. Due to bounded battery power these nodes are having very limited memory and processing capacity. Since battery replacement or recharge in sensor nodes is nearly impossible, power consumption becomes one of the most important design considerations in WSN. So one of the most important requirements in WSN is to increase battery life and network life time. Seeing as data transmission and reception consume the most energy, it’s critical to develop a routing protocol that addresses the WSN’s major problem. When it comes to sending aggregated data to the sink, hierarchical routing is critical. This research concentrates on a cluster head election system that rotates the cluster head role among nodes with greater energy levels than the others.We used a combination of LEACH and deep learning to extend the network life of the WSN in this study. In this proposed method, cluster head selection has been performed by Convolutional Neural Network (CNN). The comparison has been done between the proposed solution and LEACH, which shows the proposed solution increases the network lifetime and throughput.

Opis:

Wireless Sensor Networks (WSNs) have existed for many years and had assimilated many interesting innovations. Advances in electronics, radio transceivers, processes of IC manufacturing and development of algorithms for operation of such networks now enable creating energy-efficient devices that provide practical levels of performance and a sufficient number of features. Environmental monitoring is one of the areas in which WSNs can be successfully used. At the same time this is a field where devices must either bring their own power reservoir, such as a battery, or scavenge energy locally from some natural phenomena. Improving the efficiency of energy harvesting methods reduces complexity of WSN structures.

Opis:

Wireless sensor network consists of numerous small and low cost sensors which collect and transmit environmental data. These nodes are spatially distributed and capable of measuring their ambient. Sensor node is responsible for collecting data in regular intervals, converting the obtained data into electronic signals and transmitting data to sink node or base station through reliable wireless communications. Moreover, these nodes are supplied by non-rechargeable batteries with limited energy. Lifetime and network coverage are crucial factors in WSNs. Thus, particular algorithms must be employed so that energy consumption is reduced. In this paper two clustering algorithms LEACH and HEED are investigated.

Opis:

Bezprzewodowe sieci sensorowe, ze względu na rozmieszczenie ich elementów w terenie, są narażone na szereg zagrożeń. Zagrożenia te mogą wynikać ze świadomych akcji ludzi starających się ją nielegalnie wykorzystać lub unieszkodliwić takich, jak ataki terrorystyczne, podsłuchiwanie transmisji, czy podszywanie się pod użytkownika. Mogą one jednak być rezultatem zakłóceń środowiskowych takich, jak silny sygnał radiowy lub pożar. Sieci sensorowe w większości zastosowań mają ograniczone zasoby energii i możliwości obliczeniowe węzłów w porównaniu do kablowych sieci informatycznych. Tym ambitniejsze staje się zadanie zapewnienia im bezpiecznej pracy, w taki sposób, by nawet przy problemach ze środowiskiem lub podczas wrogich atakaów ludzi mogły spełniać swoją zasadniczą funkcję zbierania danych z czujników i przesyłaniu tych danych użytkownikowi zgodnie z jego potrzebami. Ze względu na rosnące zapotrzebowanie, w różnych dziedzinach działań człowieka, na sieci sensorowe powstaje w ostatnich latach wiele prac naukowych dotyczących systemów zapewniających ich bezpieczną pracę. Niniejsza publikacja ma na celu przybliżenie czytelnikom, a szczególnie projektantom systemów wykorzystujących sieci sensorowe, efektów tych prac oraz usystematyzowanie problemów w tej dziedzinie. W pracy przedstawiono podstawowe cechy najczęściej spotykanych ataków oraz techniki stosowane w sieciach sensorowych dla uzyskania bezpieczeństwa protokołu komunikacji, zabezpieczenia stacji bazowych przed identyfikacją i atakiem. Całkowita anonimowość jest niemożliwa, ale opisano sposoby uzyskania kompromisu między anonimowością a potrzebami systemu monitorowania. Opisano techniki wykrywania intruzów w sieci i udaremniania ataku złośliwym węzłom, które zdobyły już jeden lub kilka kluczy kryptograficznych zaatakowanej sieci oraz techniki bezpiecznego grupowania danych. Następnie przedstawiono sposoby obrony przed fizycznymi atakami, techniki wykrywanie ataków i na zakończenie perspektywy w tej dziedzinie.

Opis:

Data aggregation is the process aimed at reducing the transmission count of packets being transmitted in the framework of in-network data processing. It is the data transmission model that takes the information transmitted from different nodes and generates a single data packet after finding and eliminating the redundant packets. Accordingly, this process decreases the transmission count and makes it possible to consume less energy. The major issues in data aggregation mechanism are related to reduction of latency and to energy balancing. Moreover, it is very complex to resolve the issue of packet loss, which is the failure of one or more transmitted packets to arrive at their destination due to the bad and/or congested channel conditions. The present survey involves a collection of 50 research papers dealing with the data aggregation models in wireless sensor networks (WSN). Various data aggregation methods, like the cluster-based approach, structure-free method, tree-based approach, in-network methods, and energy based aggregation model are considered in this survey, regarding the application and the energy usage involved. On the basis of the survey, the issues and drawbacks faced by the respective methodologies are highlighted. In addition, the paper presents simple statistics of the studies considered with respect to the performance measures, simulation tools, publication year, and classification of methods. The future dimensions of the respective research are supposed to be based on the challenges identified in this survey.

Opis:

The data aggregation process of wireless sensor networks faces serious security problems. In order to defend the internal attacks launched by captured nodes and ensure the reliability of data aggregation, a secure data aggregation mechanism based on constrained supervision is proposed for wireless sensor network, which uses the advanced LEACH clustering method to select cluster heads. Then the cluster heads supervise the behaviors of cluster members and evaluate the trust values of nodes according to the communication behavior, data quality and residual energy. Then the node with the highest trust value is selected as the supervisor node to audit the cluster head and reject nodes with low trust values. Results show that the proposed mechanism can effectively identify the unreliable nodes, guarantee the system security and prolong the network life time.

This paper presents research, design and simulations of an energy efficient wireless sensor network. It describes a routing protocol designed for evenly energy consumption. There is shown how to simulate a network in the Scilab environment. The test wireless sensor network including a measurement station and construction of radio modules are presented. The radio modules consists of Texas Instruments/chipcon's CC1100 transceiver and Atmel's ATmega32 microcontroller. The network can join up to 65535 radio modules (16 bit addressing). The measurement station consists of programmable power supply, an oscilloscope, precise multimeters and a JTAG module. It allows measuring the current consumption in different working modes, checking the time of operations and controlling the radio system. This solution will be used in a wireless water meter network. The most important feature in this application is a long working time (up to 10 years). The even energy consumption should extend the network reliability and its time of work.

Opis:

This paper presents a fuzzy logic-based, service differentiated, QoS aware routing protocol (FMSR) offering multipath routing for WSNs, with the purpose of providing a service differentiated path meant for communication between nodes, based on actual requirements. The proposed protocol initially forms a cluster by fuzzy c-means. Next, the building of a routing follows, so as to establish multiple paths between nodes through the modified QoS k-nearest neighborhood, based on different QoS constraints and on optimum shortest paths. If one node in the path fails due to lack of residual energy, bandwidth, packet loss, delay, an alternate path leading through another neighborhood node is selected for communication. Simulation results show that the proposed protocol performs better in terms of packet delivery ratio, delay, packet drop ratio and throughput compared to other existing routing protocols.

Opis:

Providing Privacy and security for aggregated data in wireless sensor networks has drawn the attention of practicing engineers and researchers globally. Several cryptographic methods have been already proposed to solve security and data integrity problems for aggregated data. Matrix cryptography is a better option for creating secure encryption/decryption algorithms to counter quantum attack. However, these algorithms have higher computational cost and increased communication overhead. Hence, a new technique of loss-less secure data aggregation in Clustered Wireless Sensor Networks is presented. The proposed method uses integer matrices as keys for data security and data integrity. Matrix operations are carried out in finite field Zp. Loss-less secure data aggregation is extended for homomorphic summation while the cipher text expansion ratio is kept substantially low. The proposed algorithm has inbuilt fast and efficient signature verification facility. The execution time of our signature verification mechanism is found to be approximately 50 percent less compared to a couple of standard existing signature verification schemes.

The Late advances in WSN now witness the expanded enthusiasm for the potential use in applications like Environmental, Military, Space Exploration, Health (Scanning), Vehicular Movement, disaster management, Mechanical anxiety levels of appended objects, battle field observation and so forth. Sensors are required to be remotely conveyed in unattended situations. Propels in WSN innovation has given the accessibility of little and minimal effort sensor hubs with a capacity of sensing different sorts of physical and natural environment conditions, wireless communication and data processing. Assortment of sensing capacities results in bounty of application areas. However, the attributes of WSN require more powerful strategies for data forwarding. The sensor hubs in WSN have a constrained transmission range, and their handling and capacity abilities and as well as their energy assets are also restricted. Routing protocols for WSN are in charge of keeping up the routes in the network system and need to guarantee dependable multi-hop communication under these conditions. Routing as one key innovations of wireless sensor systems has now turned into a hot examination on the grounds that the uses of WSN are all over the place, it is unthinkable that there is a routing protocol suitable for all applications. In this paper, we give an overview of routing issues routing protocols for Wireless Sensor Network.

Opis:

Trust plays an important role in human life environments. That is why the researchers has been focusing on it for a long time. It allows us to delegate tasks and decisions to an appropriate person. In social sciences trust between humans was studied, but it also was analyzed in economic transactions. A lot of computer scientists from different areas, like security, semantic web, electronic commerce, social networks tried to transfer this concept to their domains. Trust is an essential factor in any kind of network, whether social or computer. Wireless sensor networks (WSN) are characterized by severely constrained resources, they have limited power supplies, low transmission bandwidth, small memory sizes and limited energy, therefore security techniques used in traditional wired networks cannot be adopted directly. Some effort has been expended in this fields, but the concept of trust is defined in slightly different ways by different researchers. In this paper we will show how the family of Role-based Trust management languages (RT) can be used in WSN. RT is used for representing security policies and credentials in decentralized, distributed access control systems. A credential provides information about the privileges of users and the security policies issued by one or more trusted authorities.

Wireless sensor networks (WSNs) have experienced enormous growth, both in terms of the technology used and their practical applications. In order to understand the features of WSNs that make the solution suitable for a specific purpose, one needs to be aware of the theoretical concepts behind and technological aspects of WSNs. In this paper, the significance of WSNs is illustrated, with a particular emphasis placed on their demands and on understanding researchrelated problems. A review of the literature available is presented as well. Detailed discussions concerning sensor node architecture, different types of sensors used and their relevance for various types of WSNs is presented, highlighting the need to achieve application-specific requirements without degrading service quality. Multipath and cluster-based routing protocols are compared in order to analyze QoS requirements they are capable of satisfying, and their suitability for different application areas is reviewed. This survey highlights the performance of different routing protocols, therefore providing guidelines enabling each of the routing techniques to be used, in an efficient manner, with factors such as specific network structure, protocol operation and routing path construction taken into consideration in order to achieve better performance.

To give the motivation behind energy efficient secure networks, first, the security requirements of wireless sensor networks are presented and the relationships between network security and network lifetime limited by often insufficient resources of network nodes are explained. Second, a short literature survey of energy aware security solutions for use in WSNs is presented.

Many Sensor Node could detect similar event, which increases the overall bandwidth utilization to transmit redundant data. Here Nodes computation is cheaper than communication in terms of energy. So the technique of Data Aggregation is applied to summarize data which decreases the amount of data transmitted in the network, which in turn increases the lifetime of the network. Many Data aggregation protocols are based on a structured approach which is suitable for data collection application. But maintenance of the structure is an extra overhead and this approach is not suitable for dynamic scenario. So we propose an ad-hoc data aggregation protocol for dynamic scenario mainly event based application.

Opis:

Ad hoc networks are the ultimate technology in wireless communication that allow network nodes to communicate without the need for a fixed infrastructure. The paper addresses issues associated with control of data transmission in wireless sensor networks (WSN) - a popular type of ad hoc networks with stationary nodes. Since the WSN nodes are typically battery equipped, the primary design goal is to optimize the amount of energy used for transmission. The energy conservation techniques and algorithms for computing the optimal transmitting ranges in order to generate a network with desired properties while reducing sensors energy consumption are discussed and compared through simulations. We describe a new clustering based approach that utilizes the periodical coordination to reduce the overall energy usage by the network.

Opis:

Received Signal Strength Indication (RSSI) plays a vital role in the range-free localization of sensor nodes in a wireless sensor network and a good amount of research has been made in this regard. One important factor is the battery voltage of the nodes (i.e., the MICAz sensors) which is not taken into account in the existing literature. As battery voltage level performs an indispensable role for the position estimation of sensor nodes through anchor nodes therefore, in this paper, we take into a account this crucial factor and propose an algorithm that overcomes the problem of decaying battery. We show the results, in terms of more precise localization of sensor nodes through simulation. This work is an extension to [1] and now we also use neural network to overcome the localization errors generated due to gradual battery voltage drooping.

This field has become increasingly more popular in recent times due to the advancement of technology, especially in the fields of miniaturization and telecommunications. The main problem of this research is the relatively untested sensing capability of a mobile wireless sensor network in an operating area that has dis‐ tributed and/or multiple locations of high interest. The purpose of this research is to discover the compatibility of a multiple‐agent coverage control system with several examples of interest functions that have multiple and/or distributed points of global maximum value in order to explore more thoroughly the performance of a given sy‐ stem in a varying environments.

One of the most popular techniques to support proper oil drive in a wellbore is a Gas Lift. In this paper we present the concept of using wireless sensornetwork (WSN) in the oil and gas industry installations. Assuming that Gas Lift Valves (GLVs) in a wellbore annulus are sensor controlled, the proper amount of injected gas should be provided. In aground installation, the optimized amount of loaded gas is a key factor in the effcient oil production.This paper considers the basic foundations and security requirements of WSN dedicated to Gas Lift Installations. Possible attack scenarios and their influence on the production results are shown aswell.

Opis:

Bezprzewodowe sieci sensoryczne (BSS, ang. WSN) są coraz częściej stosowane do obserwowania czynników środowiskowych (zastosowania militarne i cywilne). Dzięki postępowi technologicznemu możliwe jest obecnie wytwarzanie węzłów o wymiarach rzędu centymetrów i w cenie poniżej kilku USD za sztukę. Pozwala to na stosowanie węzłów sensorycznych na niespotykaną dotąd skalę i otwiera nowe możliwości dla tzw. wszechobecnej komputeryzacji życia (ang. pervasive/ubiquitous computing). Początkowo, sieci sensoryczne były rozwiazaniami przewodowymi. Rozwój technik bezprzewodowych i przetwarzania danych (procesory, algorytmy, etc.) pozwolił na objęcie przez węzły sensoryczne większego terenu badań. Kolejnym krokiem było zmotoryzowanie bezprzewodowych sieci sensorycznych poprzez montaż węzłów na poruszajacych się pojazdach, co pozwoliło na jeszcze większą rozdzielczość obrazowania przy praktycznie takich samych nakładach finansowych. Artykuł ten jest wprowadzeniem w obszar bezprzewodowych i mobilnych sieci sensorycznych.
Wireless sensor networks (WSN) are used to monitor strategic (from the public safety point of view) parameters of air pollutions. Technological progress in the area of sensor networks allows manufacturing centimetre-scale sensor nodes that may cost less than a few USD per piece. This enables using sensor nodes at such a scale allowing for ubiquitous computing. Initially, the sensor networks were wired solutions. Development of wireless data processing technologies (processors, algorithms, etc.) enables to monitor much larger area compared to wired solutions. The next natural step of sensor network development was to enable mobile monitoring by mounting sensor nodes on moving vehicles, i.e. allowing for much better sensor data resolution at virtually the same cost. This article is an introduction to issues of wireless and mobile sensor networks.

Opis:

Sensor networks form a special group of distributed measurement systems that can be used to control a wide range of applications with strong requirements for packet delay minimization. This can be achieved by using appropriate algorithms responsible for packet routing. The study of communication delays show that architecture and protocols can be used to provide support for QoS in the sensor network applications. This problem is a major challenge for researchers. This paper presents a comparative analysis of selected routing algorithms and their impact on the packet delays in the work.
Dynamiczny rozwój miniaturyzacji oraz niskie zapotrzebowanie na energię przyczyniło się do wzrostu popularności bezprzewodowych sieci sensorowych. Sieci te tworząc specjalną grupę rozproszonych systemów pomiarowych, mogą być wykorzystane do obsługi szerokiej gamy aplikacji, mających silne wymagania co do opóźnień w przesyle informacji między węzłami, jak również strat powstałych podczas transmisji danych. Zakres wykorzystania sieci jest praktycznie nieograniczony, od systemów sieci czujników przeznaczonych m.in. do monitorowania środowiska (pożary, powodzie itp.), kontroli i monitoringu stanu zdrowia, zastosowań w automatyce domowej, systemach bezpieczeństwa czy systemach militarnych. Aby zapewnić prawidłowe działanie systemu wymagana jest duża stabilność pracy sieci, a więc niski poziom opóźnień w działaniu, uwarunkowany m.in. odpornością sieci na uszkodzenia. Sieć czujników musi reagować na zmiany w topologii sieci, wywołane przez awarię węzłów, brak zasilania czy różnego rodzaju zakłócenia elektromagnetyczne. Istotną kwestią dla zapewnienia odpowiedniego poziomu jakości transmisji jest zapewnienie maksymalnej wydajności, energooszczędności i minimalnego poziomu błędów. Można to osiągnąć poprzez zastosowanie odpowiednich algorytmów odpowiedzialnych za trasowanie pakietów. Przeprowadzone badania opóźnień komunikacyjnych pokazują, które architektury lub protokoły mogą zostać wykorzystane do zapewnienia wsparcia QoS dla obsługiwanych przez sieć sensorową aplikacji. Problem ten stanowi duże wyzwanie dla naukowców. W niniejszej pracy przedstawiono analizę porównawczą wybranych algorytmów trasowania i ich wpływ na opóźnienia w pracy.

Opis:

Assigning bandwidth to sensors in a Wireless Sensor Network (WSN), while using Time Division Multiple Access (TDMA) protocol, remains an important problem. Even if many solutions were proposed in the literature, nevertheless, and since 2013, we are mainly focused on the critical study and the improvement of Masri’s approach published in Telecommunication Systems journal. In this paper, we introduce an extended version of our previous approaches (see Tarek Azizi and Rachid Beghdad, 2013, 2014, 2016) based on three fundamental concepts: network architecture, TDMA protocol, and data aggregation, in order to assign the maximum bandwidth to all sensor nodes. Three solutions will be presented in detail: Spiral-Based Clustered Data Aggregation (SBCDA) architecture, Tree-Based Clustered Data Aggregation (TBCDA), and Tree-Based ClusteredWireless Sensor Network (TBC-WSN). Aggregating data can reduce the number of the packets transmitted to the sink. This is the reason why, in the three approaches here described, each cluster head (CH) collects and aggregates received packets from its child nodes, before transmitting the resulting packet to its parent, until the data reaches the sink node (base station). With a number of simulations, we will demonstrate that our approaches are very competitive with Masri’s proposition, and also with two other recent works.

Opis:

Energy consumption is one of the major challenges in wireless sensor networks, thus necessitating an approach for its minimization and for load balancing data. The network lifetime ends with the death of one of its nodes, which, in turn, causes energy depletion in and partition of the network. Furthermore, the total energy consumption of nodes depends on their location; that is, because of the loaded data, energy discharge in the nodes close to the base station occurs faster than other nodes, the model presented here, through using learning automata, selects the path appropriate for data transferring; the selected path is rewarded or penalized taking the reaction of surrounding paths into account. We have used learning automata for energy management in finding the path; the routing protocol was simulated by NS2 simulator; the lifetime, energy consumption and balance in an event-driven network in our proposed method were compared with other algorithms.

Opis:

IEEE 802.15.4 standard defines Physical (PHY) and Wireless Medium Access Control (MAC) layers for wireless sensor networks (WSN). In recent years, many types of wireless sensor networks have been developed based on this standard. Currently, probably the most popular implementation of the mentioned standard are wireless ZigBee networks. Moreover, ZigBee provides functions normally attributed to the higher layers of network protocol stack. Among those the most important functions are: routing of data, data encryption and providing redundancy connections between devices in the network. We present a slightly different approach to the construction of wireless sensor networks. This is the beginning of series of papers about implementation of the IEEE 802.15.4 standard and the previously mentioned expansion functions in the network, built with RFM wireless communication modules and ATmega processors. This paper describes the basics of compiling wireless connection and data transmission with using RFM modules. In addition, blocking and non-blocking types of connections between radio modules and ways to connect RFM modules with ATmega processors are described.

Opis:

The paper aims at localization of the anchor node (fixed node) by pursuit nodes (movable node) in outdoor location. Two methods are studied for node localization. The first method is based on LNSM (Log Normal Shadowing Model) technique to localize the anchor node and the second method is based on Hybrid TLBO (Teacher Learning Based Optimization Algorithm) - Unilateral technique. In the first approach the ZigBee protocol has been used to localize the node, which uses RSSI (Received Signal Strength Indicator) values in dBm. LNSM technique is implemented in the self-designed hardware node and localization is studied for Outdoor location. The statistical analysis using RMSE (root mean square error) for outdoor location is done and distance error found to be 35 mtrs. The same outdoor location has been used and statistical analysis is done for localization of nodes using Hybrid TLBO-Unilateral technique. The Hybrid-TLBO Unilateral technique significantly localizes anchor node with distance error of 0.7 mtrs. The RSSI values obtained are normally distributed and standard deviation in RSSI value is observed as 1.01 for outdoor location. The node becomes 100% discoverable after using hybrid TLBO- Unilateral technique.

Opis:

In nuclear facilities, the reading of the sensors is very important in the assessments of the system state. The existence of an abnormal state could be caused by a failure in the sensor itself instead of a failure in the system. So, being unable to identify the main cause of the “abnormal state” and take proper actions may end in unnecessary shutdown for the nuclear facility that may have expensive economic consequences. That is why, it is extremely important for a supervision and control system to identify the case where the failure in the sensor is the main cause for the existence of an abnormal state. In this paper, a system based on a wireless sensor network is proposed to monitor the radiation levels around and inside a nuclear facility. A new approach for validating the sensor readings is proposed and investigated using the Castalia simulator.

Energy consumed by the sensor nodes are more sporadic in a sensor networks. A skilled way to bring down energy consumption and extend maximum life-time of any sensor present can be of evenly and unevenly distributed random area networks. Cluster heads are more responsible for the links between the source and destination. Energy consumption are much compare to member nodes of the network. Re-clustering will take place if the connectivity in the distributed network failure occurs in between the cluster networks that will affects redundancy in the network efficiency. Hence, we propose pragmatic distribution based routing cluster lifetime using fitness function (PDBRC) prototype is better than the existing protocol using MATLAB 2021a simulation tool.

Opis:

With an explosive growth of wireless sensor networks (WSN), many of their features and applications have become important. Localization of sensor nodes is one of the most important problems in WSN whose accuracy has a very large impact on its performance. Global positioning system (GPS) is a well-known and powerful way which differentiates methods of its use on each node individually. But, because of high energy consuming and processing GPS, it is inappropriate for WSNs. Different algorithms are suggested to overcome the consumed cost of GPS by putting GPS on only some nodes instead of all nodes in the network for localization. So, for nodes localization, just a number of nodes exploit GPS and, they can help other nodes of network in localization via distribution of their coordinates. The use of a mobile robot to send signals to coordinate the target node localization is a good idea. The mobile robot should move in the right path and can localize node more accurately at lower cost. This paper proposes a new method to localize all nodes through some localized nodes based on graph theory in a tree and network topology. The proposed method provides better performance at the cost of accuracy and the number of nodes that can be made up of local consumption.

In a wireless sensor network (WSN), nodes are not able to recognize their position. To solve this problem, studies have been done on algorithms to achieve accurate estimation of nodes in WSNs. In this paper, we present an improvement of a localization algorithm namely Gaussian mixture semi-definite programming (GM-SDP-2). GMSDP is based on the received signal strength (RSS) to achieve a maximum likelihood location estimator. The improvement lies in the placement of anchors through the Fuzzy C-Means clustering method where the cluster centers represent the anchors’ positions. The simulation of the algorithm is done in Matlab and is based on two evaluation metrics, namely normalized root-mean-squared error (RMSE) and cumulative distribution function (CDF). Simulation results show that our improved algorithm achieves better performance compared to those using a predetermined placement of anchors.

Opis:

Wireless Sensor Network (WSN) technology has grown in importance in recent years. All WSN implementations need secure data transmission between sensor nodes and base stations. Sensor node attacks introduce new threats to the WSN. As a result, an appropriate Intrusion Detection System (IDS) is required in WSN for defending against security attacks and detecting attacks on sensor nodes. In this study, we use the Routing Protocol for Low Power and Lossy Networks (RPL) for addressing security services in WSN by identifying IDS with a network size of more or less 20 nodes and introducing 10% malicious nodes. The method described above is used on Cooja in the VMware virtual machine Workstation with the InstantContiki2.7 operating system. To track the movement of nodes, find network attacks, and spot dropped packets during IDS in WSN, an algorithm is implemented in the Network Simulator (NS2) using the Ad-hoc On-Demand Distance Vector (AODV) protocol in the Linux operating system.

Opis:

W artykule przedstawiono metody pozyskiwania energii dla autonomicznych bezprzewodowych sieci czujnikowych. Pozyskiwanie energii w takich systemach odbywa się za pomocą dedykowanych układów, w niektórych przypadkach źródłem energii może być sam obiekt pomiarowy. Źródła energii odpowiednie dla ww. zastosowań możemy przyporządkować do jednej z kategorii: ruch i wibracje, różnica temperatur, promieniowanie świetlne i fale radiowe.
The paper presents energy harvesting methods suitable for autonomous wireless sensor networks. The average power demand of a typical sensor is between 20-100 žW [1]. In such systems energy is harvested via dedicated circuits. In some cases a measured object can be an energy source. Energy sources adequate for the abovementioned applications can be assigned to one of the categories: movement and vibration, temperature differences, light radiation, radio-frequency waves [1, 2, 3]. An analysis of available solutions in terms of power density or dimensions of power harvesting circuit is required for each energy source. Another important issue is the energy source power characteristic and whether it is controllable. If harvested energy is not stored (battery), a key parameter becomes the average power. In the paper we take a close look at energy harvesting approaches, along with the underlying physics and the power output. The achievable power ranges from 0,1 žW/cm2 to 15 mW/cm2 (depending on the size of the energy harvesting unit). The highest power can be achieved with photovoltaic cells under direct exposure to the sunlight.

Opis:

The widespread availability of inexpensive equipment for creating the wireless sensor networks (WSN) [1, 2], has enabled their manifold and innovative applications in numerous fields. PASTA system (Poisson Arrivals See Time Averages ) [3, 4] for modeling "many-to-one" type WSN network has been used in the paper. In the proposed solution, single sensor-sender units remain inactive all the time except for the moments when they transmit information about the measured value randomly at Poisson epochs [5] to a central base station. Probability of collision occurrence has been determined for the fixed operating conditions of the network. The concept of a collective radio-operated measuring network with one-way transmission system (simplex) based on random access of particular sensor-sender units, constitute the most innovative aspect of the paper. The proposed solution enables the sensors with a simple hardware part to be used and allows a very short transmission protocol and the complete independence of each particular sensor-sender. Consequently, it results in saving the energy from the power source of sensors-senders.
Powszechna dostępność niedrogiego sprzętu do budowy bezprzewodowych sieci czujników (Wireless Sensor Network WSN) umożliwia ich wielorakie i nowatorskie wykorzystania w wielu dziedzinach. W pracy wykorzystujemy system PASTA (Poisson Arrivals See Time Averages) [3, 4] do modelowania sieci zbiorczej WSN [3, 4]. W proponowanym rozwiązaniu pojedyncze czujniki-nadajniki pozostają nieaktywne przez cały czas, poza momentami, kiedy wysyłają informację o wielkości mierzonej w momentach losowych poissonowskich [5] do stacji bazowej. Wyznaczono prawdopodobieństwo występowania kolizji w transmisji dla ustalonych warunków pracy sieci. Innowacją tej pracy jest koncepcja zbiorczej radiowej sieci pomiarowej z transmisją jednokierunkową (Simplex) w oparciu o losowy sposób dostępu poszczególnych czujników-nadajników. Proponowane rozwiązanie jest niezwykle proste sprzętowo. Pozwala zastosować bardzo krótki protokół transmisyjny i daje pełną niezależność czujników-nadajników (brak synchronizacji i kanału powrotnego). W konsekwencji skutkuje to dużą oszczędnością energii ze źródeł zasilających czujniki-nadajniki, łatwością realizacji i rekonfiguracji sieci.

Układ taki z założenia ma wspomagać realizację różnych algorytmów kryptografii klucza publicznego bazujących na arytmetyce modularnej. Koprocesor opisany w postaci modeli GEZEL i VHDL może w prosty sposób zostać zrealizowany w postaci układu ASIC lub uruchomiony na niskomocowym układzie FPGA.
The concept of autonomous wireless sensor networks involves energy harvesting, as well as effective management of system resources. Public-key cryptography (PKC) offers the advantage of elegant key agreement schemes with which a secret key can be securely established over unsecure channels. In addition to solving the key management problem, the other major application of PKC is digital signatures, with which non-repudiation of messages exchan-ges can be achieved. The motivation for studying a low-power and area efficient modular arithmetic algorithm comes from enabling public-key security for low-power devices that can perform under constrained environment like autonomous wireless sensor networks. This paper presents a cryptographic coprocessor tailored to the autonomous wireless sensor network constraints. Such a system is aimed at supporting the implementation of different public-key cryptosystems based on modular arithmetic in GF(p). The coprocessor key components are described as GEZEL models and can be easily transferred to VHDL and implemented in hardware.

Opis:

Time synchronization between sensor nodes to reduce the end-to-end delay for critical and real time data monitoring can be achieved by cautiously monitoring the mobility of the mobile sink node in underwater wireless sensor networks. The Alive-in-Range Medium Access Control (ARMAC) protocol monitors the delay of sensitive, critical and real-time data. The idea evolves as it involves reduction in duty cycle, precise time scheduling of active/sleep cycles of the sensors, monitoring the mobility of the sink node with the selection of appropriate queues and schedulers. The model for the path loss due to attenuation of electromagnetic wave propagation in the sea water is explained. The three-path reflection model evaluating reflection loss from the air-water and watersand interfaces as a function of distance between sensors and water depth is introduced. The algorithms for effective path determination and optimum throughput path determination are elaborated. The results verify that implementation of the Alive-in-Range MAC protocol has reduced the total number of packets dropped, the average queue length, the longest time in queue, the peak queue length and the average time in queue significantly, making it relevant for critical and real-time data monitoring.

Opis:

In a rectilinear route, a moving sink is restricted to travel either horizontally or vertically along the connecting edges. We present a new algorithm that finds the shortest round trip rectilinear route covering the specified nodes in a grid based Wireless Sensor Network. The proposed algorithm determines the shortest round trip travelling salesman path in a two-dimensional grid graph. A special additional feature of the new path discovery technique is that it selects that path which has the least number of corners (bends) when more than one equal length shortest round trip paths are available. This feature makes the path more suitable for moving objects like Robots, drones and other types of vehicles which carry the moving sink. In the prosed scheme, the grid points are the vertices of the graph and the lines joining the grid points are the edges of the graph. The optimal edge set that forms the target path is determined using the binary integer programming.

Opis:

Wireless sensor networks have attracted attention of researchers considering their abundant applications. One of the important issues in this network is limitation of energy consumption which is directly related to life of the network. One of the main works which have been done recently to confront with this problem is clustering. In this paper, an attempt has been made to present clustering method which performs clustering in two stages. In the first stage, it specifies candidate nodes for being head cluster with fuzzy method and in the next stage, the node of the head cluster is determined among the candidate nodes with cellular learning automata. Advantage of the clustering method is that clustering has been done based on three main parameters of the number of neighbors, energy level of nodes and distance between each node and sink node which results in selection of the best nodes as a candidate head of cluster nodes. Connectivity of network is also evaluated in the second part of head cluster determination. Therefore, more energy will be stored by determining suitable head clusters and creating balanced clusters in the network and consequently, life of the network increases.

Opis:

Wireless Sensor Networks (WSNs) have been used in numerous applications to remotely gather real-time data on important environmental parameters. There are several projects where WSNs are deployed in different locations and operate independently. Each deployment has its own models, encodings, and services for sensor data, and are integrated with different types of visualization/analysis tools based on individual project requirements. This makes it dicult to reuse these services for other WSN applications. A user/system is impeded by having to learn the models, encodings, and services of each system, and also must integrate/interoperate data from different data sources. Sensor Web Enablement (SWE) provides a set of standards (web service interfaces and data encoding/model specications) to make sensor data publicly available on the web. This paper describes how the SWE framework can be extended to integrate disparate WSN systems and to support standardized access to sensor data. The proposed system also introduces a web-based data visualization and statistical analysis service for data stored in the Sensor Observation Service (SOS) by integrating open source technologies. A performance analysis is presented to show that the additional features have minimal impact on the system. Also some lessons learned through implementing SWE are discussed.

W artykule przedstawiono układ generatora liczb pseudolosowych dostosowany do specyfiki autonomicznych bezprzewodowych sieci czujnikowych. Realizacja podstawowych usług kryptograficznych wymaga dostarczenia liczb losowych, jednak ze względu na asymetrię zasobów (ograniczona moc zasilania i zasoby po stronie czujnikowej) konieczny jest dobór algorytmów i optymalizacja implementacji sprzętowej według kryterium mocy rozpraszanej.
The paper presents a pseudo-random number generator circuit tailored to the specific properties of autonomous wireless sensor networks [1, 2]. Implementation of essential cryptographic services, like zero-knowledge proof entity authentication [3], requires delivery of random numbers. The concept of autonomous wireless sensor networks involves energy consumption from the environment, as well as efficient management of system resources. Due to the asymmetry of resources (insufficient power and computing resources on the sensor side) careful selection of the algorithm and low-power implementation of the random number generator are required. Therefore we chose to implement the BBS algorithm (Blum-Blum-Shub generator) whose security is based on the integer factorization problem and whose operation is based on modular multiplication. In order to reduce power dissipation, we decided to implement the Montgomery modular multiplication algorithm in a bit-serial fashion. Due to the proposed modifications on algorithm and architecture level, the generator is suitable for use in constrained environments like autonomous wireless sensor networks. The power consumption is only 141 žW for an Actel Igloo low-power FPGA AGLN250V2 device operating at 100 kHz (1024 bit operands).

Opis:

A low-voltage RF CMOS receiver front-end and an energy harvesting power circuit for a piezoelectric source are presented as a co-designed solution for a Wireless Sensor Node. A MOSFET-only Wideband balun LNA with noise cancelling and a 0.6 V supply voltage is designed in conjunction with a passive mixer. The passive mixer operates in current mode, allowing a minimal introduction of voltage noise and a good linearity. The receiver front-end reaches a total voltage conversion gain of 31 dB, a 0.1-5.2 GHZ bandwidth, an IIP3 value of -1.35 dBm, and a noise figure inferior to 9 dB. The total power consumption is 1.95 mW. The energy harvesting power circuit consists of an active full bridge cross-coupled rectifier followed by a low-dropout (LDO) regulator, and it is able to guarantee a power output of 6 mW with a regulated output voltage of 0.6 V, for typical vibration patterns.

Opis:

The paper describes an idea and realization of a system for collecting and processing data from different types of wireless distributed sensors. The system consists of wireless sensor networks. Each network consists of a server connected to the Internet and theoretically unlimited number of clients. The described server has been built with two types of microcomputers. It provides tools for data collecting and processing. A client, described in Section 5, can be implemented on any PC (Personal Computer) with Windows or Linux including the Raspberry PI and any other microcomputer with HDMI joint. It allows providing an interactive signboard. The data coming from a wireless measuring unit is stored in the server. Two versions of the measuring unit (Section 6) were developed. They differ in wireless modules (compared in Section 2). The first solution uses XBee-PRO 868. The second one uses CC-2530 working in ISM 2.4GHz band. The coverage comparison of both solutions is presented in Section 7. The system can be adjusted to measure any environmental value starting with temperature, humidity and ending with more advanced like the chemical composition of air. There is also included comparison with existing commercial solutions.

Opis:

Wireless sensor networks (WSNs) are ad hoc and self-configuring networks having the possibility that any sensor node can connect or leave the network. With no central controller in WSN, wireless sensor nodes are considered responsible for data routing in the networks. The wireless sensor nodes are very small in size and have limited resources, therefore, it becomes difficult to recharge or replace the battery of the sensor nodes at far places. The present study focused on reducing the battery consumption of the sensor nodes by the deployment of the newly proposed Fault Tolerance Multipath Routing Protocol (MRP-FT) as compared with the existing Low Energy Adaptive Clustering Hierarchy (LEACH) protocol under particle swarm optimisation based fault tolerant routing (PSO-FT) technique. The proposed algorithm of MRP-FT-based on the dynamic clustering technique using Boltzmann learning of the neural network and the weights were adjusted according to the area of networks, number of nodes and rounds, the initial energy of nodes (E0), transmission energy of nodes (d

Opis:

Sieci sensorowe znajdują zastosowanie nie tylko w budowie systemów ostrzegających przed zagrożeniami naturalnymi, ale również w projektowaniu inteligentnych budynków czy specjalistycznej aparatury medycznej. System sensorowy składa się zazwyczaj z pewnej liczby węzłów pomiarowych, których zadaniem jest dostarczanie informacji o pewnych pożądanych parametrach. Parametry te mogą mówić np. o stanie poziomu wód rzecznych, stężeniu niebezpiecznych gazów czy występowaniu substancji niebezpiecznych dla środowiska naturalnego. Dobrze zaprojektowana sieć sensorowa powinna cechować się redundancją, możliwością routowania danych pomiędzy węzłami pomiarowymi oraz wykorzystaniem odpowiedniego mechanizmu dostępu do pasma komunikacyjnego. Istotną część systemu sensorowego stanowi aplikacja monitorująca oraz wizualizująca stan sensorów. W niniejszym artykule przedstawiono oryginalne podejście do budowy sieci sensorowej i wizualizacji jej działania z użyciem przestrzennych typów danych.
Because of their low cost, high availability and redundancy, wireless sensor networks are used in wide variety of applications. Today building monitoring systems which can inform about and prevent natural disasters, designing smart houses and supporting contemporary medicine are achieved by using sensor networks. When implementing a wireless sensor network, designer have to elaborate protocol which can be used to provide communication between sensors, user interface for monitoring and controlling system and database in which should be stored data from sensors. This paper presents capabilities of sensor network and spatial data types in designing smart house.

Opis:

Wraz ze wzrostem prędkości pojazdów trakcyjnych rośnie potrzeba utrzymania sieci trakcyjnej w odpowiednim stanie. Konieczny jest ciągły monitoring i diagnostyka pozwalające wykrywać zjawiska pogarszające jakość odbioru energii z sieci trakcyjnej takie jak: nadmierne zużycie nakładek stykowych czy złe nastawy odbieraka prądu pojazdu. Jedną z metod jest umieszczenie czujników przyspieszenia na górnej sieci trakcyjnej. Analiza przebiegu tej wielkości fizycznej pozwoli określić stan układu sieć jezdna - odbierak prądu. Wybranie łączności bezprzewodowej jako medium transmisyjnego pomiędzy elementami sieci sensorowej, pozwala ominąć konieczność izolacji elektrycznej elementów sieci. Projekt musi uwzględniać niskie zużycie energii a także metody jej pozyskiwania z dostępnych źródeł odnawialnych. Jako standard komunikacyjny wybrano Bluetooth 4.0 Low Energy. Jest on dedykowany dla konsumenckich urządzeń czujnikowych, lecz jego zalety mogą znaleźć zastosowanie również w obszarze przemysłu. W artykule przedstawiono projekt i realizację sieci pozwalającej zbadać przebieg przyspieszeń sieci jezdnej. Opisano wykorzystane rozwiązania sprzętowo-programowe. Zaprezentowano wstępne wyniki pomiarów laboratoryjnych.
Together with increasing traction vehicle’s speed a need to maintain a traction network in an appropriate state rises. Constant monitoring and diagnostics is necessary, allows to detect unfavorable phenomenon deteriorating power receive quality e.g.: excessive wear of contact strips, incorrect vehicle’s trolley settings. One of the methods is to place acceleration sensor on overhead contact line. Waveform’s analysis should allow estimation of traction network – trolley system shape. Wireless network selection as sensor network communication medium bypasses necessity for electric insulation between network’s elements. The design has to take into an account low power usage and renewable sources energy harvesting methods. Bluetooth 4.0 Low Energy as transmission medium was chosen. It is dedicated for customer marker, however its multiple advantages can be exploited in industrial sensors. In paper was presented design and realization of wireless sensor network to investigate the catenary line acceleration. Hardware and software solution was described. Preliminary laboratory measurement’s results were presented.

Opis:

In wireless mobile sensor networks, periodic calculation of coverage is very important, since mobile sensors can be moved adequately to current needs, thus increasing the coverage. Those moves require the execution of navigation tasks. Global network central algorithms for those tasks are very costly regarding energy consumption and computational resources. Considerations presented herein pertain to the best algorithms for a network of numerous small mobile sensor nodes used for monitoring of large terrains. Localized algorithms suggested in this paper help calculate the coverage on-line and locally with the involvement of neighboring nodes only. Furthermore, localized collaborative navigation is presented. It enables yielding position estimation with no GPS use and ensures improvement rather than deterioration over time. It uses multi-sensor fusion algorithms based on optimization and a distributed iterative extended Kalman Filter.

However, characteristic of physical environment often provides opportunities to address these problems. This paper explores concepts of enriching the WNS environment with context-based information. By context we consider all data available in sensors environment, not only data processed by them. Currently this data are not utilized by sensors, but we think that they can improve overall functionality of the sensor network. We also discuss the practical challenges facing the integration of such an approach into the sensor application stack.

Ubiquitous sensing enabled by Wireless Sensor Network (WSN) technologies cuts across many areas of modern day living. This offers the ability to measure, infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. The proliferation of these devices in acommunicating – actuating network creates the Internet of Things (IoT), wherein sensors and actuators blend seamlessly with the environment around us, and the information is shared across platforms in order to develop a common operating picture (COP). Fuelled by the recent adaptation of a variety of enabling wireless technologies such as RFID tags and embedded sensor and actuator nodes, the IoT has stepped out of its infancy and is the next revolutionary technology in transforming the Internet into a fully integrated Future Internet.

Opis:

Vehicle tracking is one of the important applications of wireless sensor networks. We consider an aspect of tracking: the classification of targets based on the acoustic signals produced by vehicles. In this paper, we present a naive classifier and simple distributed schemes for vehicle classification based on the features extracted from the acoustic signals. We demonstrate a novel way of using Aura matrices to create a new feature derived from the power spectral density (PSD) of a signal, which performs at par with other existing features. To benefit from the distributed environment of the sensor networks we also propose efficient dynamic acoustic features that are low on dimension, yet effective for classification. An experimental study has been conducted using real acoustic signals of different vehicles in an urban setting. Our proposed schemes using a na¨ive classifier achieved highly accurate results in classifying different vehicles into two classes. Communication and computational costs were also computed to capture their trade-off with the classification quality.

Opis:

Progress of ICT is shifting the paradigm of systems organization towards a distributed approach, in which physical deployment of components influences the evaluation of systems properties. This contribution can be considered as a problem of graph layout optimization, well-known in literature where several approaches have been exploited in different application fields with different solving techniques. Then again, complex systems can be only studied by means of different formalisms which codification is the aim of language engineering. Telemaco is a tool that supports a novel approach for the application of graph layout optimizations to heterogeneous models, based on the OsMoSys framework and on the language engineering principles. It can cope with different graph-based formalisms by exploiting either their core graph nature or their different specialized features by means of language hierarchies. In this paper Telemaco is introduced together with its foundations and an example of application to Wireless Sensor Networks (WSN) deployment.

Energy is one of the crucial performance parameters in wireless sensor networks (WSNs). Enhancement of network lifetime is an important consideration as well. Low energy-aware clustering hierarchy (LEACH) is one of the protocols proposed for WSNs. In this paper, a residual energy-aware clustering transformation protocol for LEACH (REACT-LEACH), enhancing performance of LEACH by introducing a clustering mechanism, is proposed. The proposed cluster head (CH) rotation and cluster reformation processes are more effective in REACT-LEACH, as residual energy is considered to be one of the metrics. Performance of REACT-LEACH is validated based on simulations.
