The opportunistic networks are the variants of Delay Tolerant Networks (DTNs). These networks can be useful for routing in places where there are few base stations and connected routes for long distances. In an opportunistic network, when nodes move away or turn off their power to conserve energy, links may be disrupted or shut down periodically. These events result in intermittent connectivity. When...
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 Exponential and Weibull distributions of mesh clients. We use as evaluation metrics giant component and number of covered mesh clients...
In this work, we consider the replacement methods in WMN-SA simulation system for 4 different distributions of mesh clients. We want to find the optimal distribution of mesh router nodes in order to provide the best network connectivity and coverage in various distributed clients. We implemented a simulation system based on Simulated Annealing (SA) algorithm, called WMN-SA, to calculate the size of...
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....
