Performance Analysis by WMN-GA Simulation System for Different WMN Architectures Considering Exponential Distribution, Different Transmission Rates and OLSR Protocol

In this paper, we evaluate the performance of two WMN architectures considering throughput, delay and fairness index metrics. For simulations, we used ns-3. We compare the performance for two architectures considering different transmission rates and OLSR protocol. The simulation results show that for 100 [kbps] transmission rate, the throughput of Hybrid WMN is higher than I/B WMN. But, for transmission rates 600 and 1200 [kbps], the throughput of I/B WMN is higher than Hybrid WMN. For transmission rates 600 and 1200 [kbps], the delay of I/B WMN is lower than Hybrid WMN. However, for transmission rate 100 [kbps], the delay of Hybrid WMN is lower compared with I/B WMN. For all transmission rates, the fairness index of I/B WMN is higher than Hybrid WMN.
