Performance Comparison Of Cm And Ldvm 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 such as: easy maintenance, low upfront cost and high robustness. The connectivity and stability affect directly the performance of WMNs. However, WMNs have some problems 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 Constriction Method (CM) and Linearly Decreasing Vmax Method (LDVM) for WMNs by using the WMN-PSOSA-DGA hybrid simulation system considering the Stadium distribution of mesh clients. Simulation results show that LDVM has better performance than CM.
