The optimization of mesh routers in Wireless Mesh Networks (WMNs) is very important in order to ensure high connectivity and better coverage. In our previous work we implemented a hybrid simulation system based on intelligent algorithms called WMN-PSOHCDGA. We investigated the performance for different scenarios and found that some mesh routers were concentrated in different areas. In this paper, we assess the performance of a small scale WMN for different number of mesh routers and Subway distribution of mesh clients considering Blend Crossover (BLX- \(\alpha \) ) and Simplex Crossover (SPX). While as mesh router replacement method is utilized the Fast Convergence Rational Decrement of Vmax Method (FC-RDVM). We consider two scenarios for 16 and 10 mesh routers and three evaluation metrics: connectivity, coverage and load balancing. The evaluation results show that even for 10 mesh routers was possible to connect all mesh routers and cover all mesh clients for both crossover methods. Considering load balancing, for both scenarios SPX has better performance than BLX- \(\alpha \) .
