Opis:
IoT (Internet of Things) is certainly one of the leading current and future trends for processing in the current distributed world. It is changing our life and society. IoT allows new ubiquitous applications and processing, but, on the other hand, it introduces potentially serious security threats. Nowadays researchers in IoT areas should, without a doubt, consider and focus on security aspects. This paper is aimed at a high-level review of the existing IoT enabling standalone middleware solutions and frameworks in terms of potential application areas, architecture and components, communication APIs as well as support for key security features including access control, support against attacks on service, device authorization and data filtering. On the one hand, it allows the developer to choose the middleware best matching their needs. On the other hand, it can serve as a starting point for further research on middleware security features based on the provided security related open areas and challenges.

Opis:
The Internet of Things vary in different complexities and capabilities at their end points ranging from RFID tags, to sensors and actuators that can be wired or wirelessly networked and interconnected. To deal with such heterogeneity, IoT-A architecture virtualizes IoT devices and their capabilities. It provides a unifying IoT resource abstraction. The abstraction of IoT provides so many advantages such as simplified management, discovery of heterogeneous IoT devices ensuring the interactions between them and the combining of these interactions takes place in a uniform manner. From business process perspective and end user applications, IoT resources can be used as service end points. These can be embedded in service oriented enterprise systems and service delivery platforms.

Opis:
Celem badań podjętych w tym artykule jest analiza świata Internetu Rzeczy (IoT) rozumianego nie tylko w sensie technologicznym (technologia dla samej technologii i zysków ekonomicznych), lecz również w znaczeniu społecznym (technologia w służbie rozwojowi społeczeństw, ich potrzeb i bezpieczeństwa). Głównymi założeniami, wokół których dokonano analizy tzw. świata smart, stającego się wielkim systemem informacyjnym, są: a) przekonanie, iż mimo ciągłego wzrostu liczby urządzeń podłączanych do Internetu, nadal wiele z ich możliwości dla domu lub pracy pozostaje nieodkrytych, a świadomość korzyści, jakie może przynieść Internet Rzeczy dla jego użytkowników, nadal jest niska; b) poszerzenie dostępu do Internetu urządzeń i procesów, które pierwotnie nie były do tego przystosowane, może mieć istotny wpływ na wzrost poczucia zagrożenia bezpieczeństwa personalnego, stanowiącego efekt hipersprawczości podmiotu bezpieczeństwa, którym jest człowiek. W celu precyzyjnego omówienia podjętego problemu dokonano analizy zagadnień świata IoT zarówno w wymiarze teoretycznym (zastosowano metodę analizy i krytyki piśmiennictwa), jak i empirycznym (wykorzystano metodę sondażu).
The aim of the research undertaken in this article is to analyze the world of the Internet of Things (IoT) understood not only in a technological sense (technology for technology’s sake and economic gain), but also in a social sense (technology in the service of the development of societies, their needs and security). The main assumptions around which the analysis of the so-called smart world, which is becoming a large information system, was made are: a) the belief that despite the continuous increase in the number of devices connected to the Internet, still many of their capabilities for the home or work remain undiscovered, and the awareness of the benefits that the Internet of Things can bring to its users is still low; b) the expansion of access to the Internet of devices and processes that were not originally designed for it, can have a significant impact on the increase in the sense of personal security risk, which is the result of the hyper-powerfulness of the security subject, which is a person. In order to accurately discuss the problem undertaken, the issues of the IoT world were analyzed both in the theoretical dimension (the method of analysis and criticism of the literature was used) and empirical (the method of survey was used).

This paper proposes an advanced routing method in the purpose of increasing IoT routing device’s power-efficiency, which allows to centralize routing tables computing as well as to push loading, related to routing tables computation, towards the Cloud environment at all. We introduced a phased solution for the formulated task. Generally, next steps were performed: stated requirements for the system with Cloud routing, proposed possible solution, and developed the whole system’s structure. For a proper study of the efficiency, the experiment was conducted using the developed system’s prototype for real-life cases, each represents own cluster size (several topologies by each size), used sizes are: 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27 and 29. Expectable results for this research – decrease the time of cluster’s reaction on topology changes (delay, needed to renew routing tables), which improves system’s adaptivity.

Containerization
Opis:
The Internet of Things gets bigger and bigger audiences. This topic is really popular in science and also in industry. There are many fields for research. One of them is efficient deployment against resource utilization. Another one is containerization within IoT platforms. One of the commonalities of these two topics is different CPU affinity against containerized platforms to get the best performance. There were plenty of papers dedicated to containerization even in IoT but none of these focused on core affinity. As this survey analyzes the scalability and stability of the platform in different core-container configurations based on the IoT platform - DeviceHive, it brings a novelty to this area. Most interesting observations were made in the field of the same configurations in terms of the number of nodes but varying with core affinity. Analyzed observations may be useful during the architecture planning phase for containerized IoT platforms.

Opis:
The use of the Amazon Web Services cloud enables new functionalities that are not possible with traditional solutions: low latency, local data processing and storage, and direct connectivity to other cloud services. Reimagining the way IoT connectivity services are presented by combining AWS cloud technology with mobile connectivity offers rapid prototyping to help connect devices natively over Wi-Fi. For this, the MQTT communication protocol is used to interact with the IoT device and exchange data, which allows controlling the basic functions of a sensor node. The installation is realized through a software development kit (SDK), which allows the creation of an application for Android devices. This solution gives the option to integrate together, improving the connectivity of the IoT system. The results enable board logging and network configuration, and can also be used to control the IoT device. The embedded firmware provides the required security functions.

Opis:
The development of IoT (the Internet of Things) wireless transmission opens a new era in communication systems. In the next years, the development and implementation of IoT systems will be very dynamic. It can be seen that the solutions of LTE – NB-IoT (Long Term Evolution – Narrowband IoT) transmission devices are implemented in a wide range of terrestrial solutions, e.g. smart grids. This paper aims to analyse the possibility of the use of NB-IoT technology for maritime communication applications and partially, for some maritime safety solutions, based on signal coverage analysis at sea. An interesting approach is the comparison of the results of NB-IoT coverage to the classic cellular LTEbased communication systems. Proposed solutions are based on the practical implementation of a designed specialised data concentrator with implemented gateway and radio modems, for both NB-IoT technology as well as LTE. In the paper, analyses of radio link budget and propagation loss models for sea environment are presented. The coverage analysis is based on real measurements of the efficiency of transmissions using wireless modems implemented in the developed data concentrator.

Opis:
Strong requirements for automation in the production processes using machine tools have been increasing due to lack of high-skilled machining engineers. Automation used to be utilised in mass production, but it is also necessary in medium- to low-volume production recently. Next requirements will be monitoring or sensing functions to make the following possible: prompt service when the machine stops; detection of abnormality before the machine breaks down; and compensation of thermal displacement to ensure machining accuracy. These now need to be performed automatically in place of operators so that abnormality can be detected during machining operation. In this paper core technologies to support automation system will be discussed which are operation monitoring, predictive maintenance, sensing interface and thermal displacement compensation as a sensing application.

RESEARCH OBJECTIVE: The aim of this article is to call the attention to specific social behaviors that have been generated by the indiscriminate use of the technologies. We want to make evident that those behaviors cause a detriment of the communication between the members of the Mexican families, causing in consequence that minors are being neglected by parents and the lack of adequate parental control in the face of the risks associated with the use of certain technologies. THE RESEARCH PROBLEM AND METHODS: The presented study involves the relation between people’s behaviors related to their access to certain technologies face to the concept of family and its importance in the society for an interconnected world. We make an in-depth study of the academic and informative literature which deals with the phenomena called phubbing. We refer to varied research, both technical and empirical and applied the inductive method and critical analysis, taking into consideration previous official, as well as non-official, researches that demonstrate phubbing adverse effects in communication between Mexican family’s members. THE PROCESS OF ARGUMENTATION: In the first part of the research we defined the concept of family in Mexican Law and how the political agenda proposes the use of technologies in order to have a greater development of the society that can turn in better opportunities and conditions of life of the individuals in general and families in particular. In a second part we refer the specific Internet penetration in Mexico as a consequence of the above mentioned agenda. Finally, in a third part, we analyze the phenomena called phubbing and its impact in Mexican Families that is the essential part of our argumentation. RESEARCH RESULTS: The result of this argumentation ends to some advices that deal with better practices in the usage of technologies in order to prevent adverse effects in Mexican families without renouncing to the incorporation of technologies in our daily life routines. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: Even though the consequences of phubbing in our society are evident, we cannot yet accurately count its effects. There are data regarding the time that parents spend with their children compared to the average time they spend using applications, video games, e-mail, social networks, and media in general. The disorganization in the time we spend in leisure, work and family life turns evident. This situation invites us to reflect about the role technologies play in relation to our family integration or disintegration. Hyper-connectivity has generated adverse conditions for individuals, both physical and psychological, that result in an affection towards the fundamental pillar of our society that is the family. It is noted that the Mexican government needs to face the growing wave of phubbing, by informing its society about the risks of the abuse of the use of technologies in one hand, and to promote programs to invite people to a more conscious access to social networks by best practices of the other. Only in that way we can grant the principle of freedom and family autonomy in Mexico. Otherwise, how can we refer to a family autonomy if its members that make up the core of society have stopped communicating?

Opis:
Covering a wide area by a large number of WiFi networks is anticipated to become very popular with Internet-of-things (IoT) and initiatives such as smart cities. Such network configuration is normally realized through deploying a large number of access points (APs) with overlapped coverage. However, the imbalanced traffic load distribution among different APs affects the energy consumption of a WiFi device if it is associated to a loaded AP. This research work aims at predicting the communication-related energy that shall be consumed by a WiFi device if it transferred some amount of data through a certain selected AP. In this paper, a forecast of the Energy consumption is proposed to be obtained using an algorithm that is supported by a mathematical model. Consequently, the proposed algorithm can automatically select the best WiFi network (best AP) that the WiFi device can connect to in order to minimize energy consumption. The proposed algorithm is experimentally validated in a realistic lab setting. The observed performance indicates that the algorithm can provide an accurate forecast to the energy that shall be consumed by a WiFi transceiver in sending some amount of data via a specific AP.
