Abstract
In our previous work, we presented WMN-GA (Wireless Mesh Networks-Genetic Algorithm) system. In this paper, we use WMN-GA and analyze the simulation results considering packet delivery ratio (PDR), throughput and delay metrics. For simulations, we used ns-3 simulator and Hybrid Wireless Mesh Protocol (HWMP). We evaluate the performance of WMN for Exponential and Weibull distributions by sending multiple constant bit rate (CBR) flows and different transmission rates in the network. From simulation results, we found that for 10, 20 and 30 number of connections, the PDR is less than 60% when the transmission rate is more than 1200 kbps for Exponential distribution. The PDR for Weibull distribution is higher than Exponential distribution. For different number of connections, the throughput is increased linearly with the increasing of the transmission rate. The throughput of Exponential distribution is higher than Weibull distribution. With increasing of the number of the connections and the transmission rate, the delay is increased. For 10 connections, the delay is very small until the transmission rate is 800 kbps. The delay of Exponential distribution is smaller than that of Weibull distribution.
