In this paper, we propose and evaluate a new fuzzy-based reliability system for Peer-to-Peer (P2P) Communications in JXTA-Overlay platform considering as a new parameter the sustained communication time. In our system, we considered four input parameters: Data Download Speed (DDS), Local Score (LS), Number of Interactions (NI) and Sustained Communication Time (SCT) to decide the Peer Reliability (PR)...
With the advancement of new technologies, such as 5G and Internet of Things (IoT), there is an increasing interests in heterogeneous and autonomous Information and Communication Technology (ICT) systems. Wireless Sensor and Actor Network (WSAN), as an emerging autonomous ICT system, will soon be an important part of our technological reality. One of the main challenges in autonomous systems is power...
In Wireless Sensor and Actor Networks, sensors and actors collaborate to get the information about the physical environment and perform appropriate actions. In order to provide effective sensing and acting, a distributed local coordination mechanism is necessary among sensors and actors. In this work, we implement and compare two Fuzzy-Based Systems (FBS1 and FBS2) for actor selection problem. These...
In this paper, we used our proposed and implemented system based on Hill Climbing algorithm, called WMN-HC for mesh router node placement in WMNs. We evaluate and compare the performance of the proposed system for different movement methods. We took into consideration Normal and Uniform distributions of mesh clients. We use as evaluation metrics giant component and number of covered mesh clients....
In this paper, we deal with connectivity and coverage problem in Wireless Mesh Networks (WMNs). We used Friedman test to compare Genetic Algorithm (GA) and Tabu Search (TS). We found out that GA and TS have difference in their performance. Then, we used the implemented systems WMN-GA and WMN-TS to evaluate and compare the performance of the system for different distributions of mesh clients in terms...
With the fast development of wireless technologies, Wireless Mesh Networks (WMNs) are becoming an important networking infrastructure due to their low cost and increased high speed wireless Internet connectivity. In this paper, we propose and implement a system based on Hill Climbing algorithm, called WMN-HC for mesh router node placement in WMNs. We evaluate the performance of the proposed system...
Wireless Mesh Networks (WMNs) are important networking infrastructure for providing cost-efficient broadband wireless connectivity. Mesh router node placement is important to achieve network connectivity and coverage in such networks. In this paper, we deal with the effect of changes in population size and number of generations for node placement problem in WMNs. We consider two population sizes 8...
Vehicular Ad-hoc Networks (VANETs) represent a rapidly emerging, particularly challenging class of Mobile Ad-hoc Networks (MANETs). VANETs are expected to be massively deployed in upcoming vehicles, because their use can improve the safety of driving and makes new forms of inter-vehicle communications possible as well. Because they are characterized of high mobility and dynamic topology change, congestion...
Online web-based application that heavily require user interaction, either among users or among users and the application, generate huge amounts of data. Recording such user interaction data, usually in the form of log data files, could be very useful for different purposes such as user modelling, user activity analysis, data analytics, security, monitoring, etc. However, such data is not ready to...
Wireless Mesh Networks (WMNs) distinguish for they low cost nature that makes them very attractive for providing wireless Internet connectivity. Such infrastructures can be used to deploy community networks, metropolitan area networks, municipal and corporative networks, and to support applications for urban areas, medical, transport and surveillance systems. The main issues in WMNs are achievement...
Wireless Mesh Networks (WMNs) are currently attracting a lot of attention from wireless research and technology community due to their importance as means for providing cost-efficient broadband wireless connectivity. WMNs are based on mesh topology, in which every node is connected to one or more nodes, enabling thus the information transmission in more than one path. In this paper, we propose a system...
Node placement problems have been long investigated in the optimization field due to numerous applications in location science and classification. Facility location problems are showing their usefulness to communication networks, and more especially from Wireless Mesh Networks (WMNs)field. Recently, such problems are showing their usefulness to communication networks, where facilities could be servers...
In VANETs and MANETs, the topology of the network changes very often, therefore implementation of efficient routing protocols is very important problem. In this paper, we investigated the good put of AODV, OLSR and DYMO routing protocols using CAVENET (Cellular Automaton based Vehicular Network). The simulation results show that the number of hops for DYMO is smaller than AODV and bigger than OLSR...
