Assessment of FC-RDVM and LDIWM Router Replacement Methods by WMN-PSOHC Hybrid Simulation System Considering Chi-Square Mesh Client Distribution

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. However, there are many issues in WMNs such as hidden terminal problem, guaranteeing network connectivity and coverage, which are closely related to the node placement problems and are known to be NP-hard. This paper focuses on the node placement problem in Wireless Mesh Networks (WMNs). We implemented a hybrid intelligent simulation system called WMN-PSOHC, which combines Particle Swarm Optimization (PSO) and Hill Climbing (HC). We assess the performance of Fast Convergence Rational Decrement of Vmax Method (FC-RDVM) with Linearly Decreasing Inertia Weight Method (LDIWM) considering the Chi-Square distribution of mesh clients. The simulation results show that FC-RDVM performs better than LDIWM for the considered scenario.
