Performance Evaluation of WMNs by WMN-PSOSA System Considering Chi-square and Exponential Client Distributions

Abstract

Wireless Mesh Networks (WMNs) have many advantages such as low cost and increased high-speed wireless Internet connectivity, therefore WMNs are becoming an important networking infrastructure. In our previous work, we implemented a Particle Swarm Optimization (PSO) based simulation system for node placement in WMNs, called WMN-PSO. Also, we implemented a simulation system based on Simulated Annealing (SA) for solving node placement problem in WMNs, called WMN-SA. Then, we implemented a hybrid simulation system based on PSO and SA, called WMN-PSOSA. In this paper, we analyse the performance of WMNs by using WMN-PSOSA considering two types of mesh clients distributions. Simulation results show that a good performance is achieved for Exponential distribution compared with the case of Chi-square distribution.
