Opis:
Mobile ad hoc networks have consisted of the nodes which are freely displaced. In other words, this network has dynamic topology. Routing protocols find route of forwarding data packets from the source node to the destination node. A routing protocol plays important role in finding the shortest time and the route path. In this paper, considering significance of the subject, attempt has been made to present a model using fuzzy logic approach to evaluate and compare two routing protocols i.e. AODV DSDV using effective factor of the number of nodes based on 2 outputs of delay and throughput rate (totally fuzzy system with four outputs) in order to select one of these two routing protocols properly under different conditions and based on need and goal. To show efficiency and truth of fuzzy system, two protocols have been evaluated completely equally using NS-2 simulator and attempt has been made to prove efficiency of the designed fuzzy system by comparing results of simulation of fuzzy system and NS-2 software.

Opis:
Vehicular Ad Hoc Networks (VANET) constitute a promising technology for Intelligent Transport Systems (ITS). VANET are highly dynamic in their nature because of the movements of vehicles, which are acting as nodes. The routing protocol must be designed for dealing with multiple limiting conditions, like link failures, handoffs, and long congestion periods, which is very challenging. The survey of different routing protocols in VANET provides a significant information for building smart ITS. Accordingly, the present survey is devoted to the existing distinct multipath routing protocols. This review article provides a detailed account on 50 research papers, presenting the different kinds of multipath routing protocols, namely proactive routing protocols, ad-hoc-based routing protocols, Greedy Perimeter Stateless Routing (GPSR), hybrid routing protocols, as well as geographic routing protocols. Besides the classification and cursory description, the present study addresses also several of the important parameters, like evaluation metrics, implementation tool, publication year, datasets utilized, Peak Signal to Noise Ratio (PSNR), and packet end-to-end delay with respect to various techniques considered. Eventually, the research gaps and issues of various multipath routing protocols are presented with the intention of pointing out directions for future research.

Opis:
The heterogeneous mobile terminals coexist in the next generation wireless networks. The most common routing schemes for mobile ad hoc networks are designed for homogeneous wireless networks. The heterogeneous wireless network routing protocols are needed urgently in many important applications. This paper improves the routing scheme utilizing different capability of terminals and the Hybrid Grid Routing Protocol (HGRP) is proposed. The network is organized in the grid form, that is, the network deployment area is divided into square cells according to the location. Each cell contains one backbone node and several ordinary nodes. This proposed protocol consists of four parts: grid construction, local routing, global routing, and routing correction. Analysis and simulation results indicate that the proposed protocol has the advantages of lower routing cost, lower energy consumption, smaller delay and higher throughput, compared to AODV and ZRP.

Opis:
Compared with traditional cellular networks, wireless ad hoc networks do not have trusted entities such as routers, since every node in the network is expected to participate in the routing function. Therefore, routing protocols need to be specifically designed for wireless ad hoc networks. In this work, we propose an authenticated routing protocol based on small world model (ARSW). With the idea originating from the small world theory, the operation of the protocol we proposed is simple and flexible. Our simulation results show the proposed ARSW not only increases packet delivery ratio, but also reduces packet delivery delay. In particularly, Using authentication theory, the proposed ARSW improves communication security.

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:
This paper presents a new global positioning system (GPS)-based routing protocol, called location-based point-to-point adaptive routing (LPAR) for mobile ad hoc networks. This protocol utilises a 3-state route discovery strategy in a point-to-point manner to reduce routing overhead while maximising throughput in medium to large mobile ad hoc networks. In LPAR, data transmission is adaptable to changing network conditions. This is achieved by using a primary and a secondary data forwarding strategy to transfer data from the source to the destination when the condition of the route is changed during data transmission. A simulation study is performed to compare the performance of LPAR with a number of different exisiting routing algorithms. Our results indicate that LPAR produces less overhead than other simulated routing strategies, while maintains high levels of throughput.

Opis:
Research on multi-path routing protocols to provide improved throughput and route resilience as compared with single-path routing has been explored in details in the context of wired networks. However, multi-path routing mechanism has not been explored thoroughly in the domain of ad hoc networks. In this paper, we analyze and compare reactive single-path and multi-path routing with load balance mechanisms in ad hoc networks, in terms of overhead, traffic distribution and connection throughput. The results reveals that in comparison with general single-path routing protocol, multi-path routing mechanism creates more overheads but provides better performance in congestion and capacity, provided that the route length is within a certain upper bound which is derivable. The analytical results are further confirmed by simulation.

Opis:
Wireless Sensor Networks (WSNs) are networks that consist of sensors which are randomly deployed in inaccessible area to gathering data and transfer it to user or base station. The most important matters considered in sensor networks are efficient utilization of energy, network lifetime, and environmental conditions changes. To provide the communication facilities within the network a routing protocol is used. There are many techniques used to route data in sensor networks, clustering based is one of most common techniques used, cluster based routing protocols can be classified to proactive and reactive protocol depending on how source finds a route to destination. This paper is aim to study and compare the two mechanisms in cluster based routing by discuss different characteristics in each mechanism, and also analyzed the performance of two mechanisms by take two exemplar protocols LEACH and TEEN from proactive and reactive mechanism respectively in order to compare the performance in same scenario and simulation parameters.

Opis:
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:
The multicasting technique supports a variety of applications that require data to be instantaneously transmitted to a set of destination nodes. In environments with continuously moving nodes, such as mobile ad-hoc networks, the search for efficient routes from sources to the projected destinations is a common issue. Proposed Windmill protocol provides a scalable multicast solution for mobile ad-hoc networks. Windmill aims to improve routing protocol’s performance by introducing a hierarchal distributed routing algorithm and dividing the area into zones. Additionally, it attempts to demonstrate better scalability, performance and robustness when faced with frequent topology changes, by utilizing restricted directional flooding. A detailed and extensive simulated performance evaluation has been conducted to assess Windmill and compare it with multicast ad-hoc on-demand distance vector (MAODV) and on-demand multicast routing protocols (ODMRP). Simulation results show that the three protocols achieved high packet delivery rates in most scenarios. Results also show that Windmill is capable of achieving scalability by maintaining the minimum packet routing load, even upon increasing the nodes’ speed, the number of sources, the number of group members and the size of the simulated network. The results also indicate that it offers superior performance and is well suited for ad-hoc wireless networks with mobile hosts. The trade-off of using Windmill consists in slightly longer paths – a characteristic that makes it a good choice for applications that require simultaneous data transmission to a large set of nodes.

Sieci DTN wykorzystują paradygmat składowania – przenoszenia i przekazywania wiadomości przy wykorzystaniu mobilnych węzłów-nośników. Zaproponowane rozwiązanie przeznaczone jest do działania w środowisku, gdzie rolę węzłów przenoszących wiadomości pełnią statki powietrzne. W rozwiązaniu przewidziano brak standardowych możliwości komunikacji oraz wykorzystanie predefiniowanych informacjach o trasie i czasie przemieszczania się statków powietrznych, tzw. planach lotu.
The paper presents routing protocol designed for wireless Delay and Disruptive Tollerant Networks (DTN). The DTN network uses the storage-carry-forward paradigm for message delivery to the destination nodes using mobile message ferries. The proposed solution is designed to operate in a specific environment, where aircrafts are playing the role of message carriers. For the algorithm purpose, we assume the use of pre-defined information about the routes and time of airplanes movement, so-called flight plans. Additionally we assume no other communication possibilities.
