Performance Analysis of RIWM and RDVM Router Replacement Methods for WMNs by WMN-PSOSA-DGA Hybrid Simulation System Considering Stadium Distribution of Mesh Clients

Wireless Mesh Networks (WMNs) have many advantages, for example easy maintenance, low upfront cost and high robustness. However, WMNs have some problems to be solved such as node placement problem, hidden terminal problem and so on. In our previous work, we implemented a simulation system to solve the node placement problem in WMNs considering Particle Swarm Optimization (PSO), Simulated Annealing (SA) and Distributed Genetic Algorithm (DGA), called WMN-PSOSA-DGA. In this paper, we compare the performance of Random Inertia Weight Method (RIWM) and Rational Decrement of Vmax Method (RDVM) for WMNs by using WMN-PSOSA-DGA hybrid simulation system considering Stadium distribution of mesh clients. Simulation results show that RDVM has better performance than RIWM.
