Application of WMN-HC Web Interface and NS-3 for Optimization and Analysis in WMNs Considering Different Number of Mesh Routers and Architectures

Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in location science. In this work, we evaluated WMN-HC system which is based on Hill Climbing (HC) to find an optimal location assignment for mesh routers. As evaluation metrics, we used throughput, one-way delay, jitter, fairness index and residual energy. For simulations, we used ns-3 and Optimized Link State Routing (OLSR). We compare the performance of the optimized network topologies by sending multiple constant bit rate flows in the network. The simulation results show that the throughput of 24 mesh routers is higher than other number of mesh routers for both WMN architectures. The delay and jitter of 24 mesh routers is lower than other number of mesh routers. The fairness index of 16 mesh routers is higher than other number of mesh routers for Hybrid WMN architecture. For 16 mesh router, the remaining energy is higher than 24 and 32 mesh routers.
