Performance Evaluation of WMN Considering Number of Connections Using NS-3 Simulator

Wireless Mesh Networks (WMNs) are currently attracting a lot of attention due to their ability to provide cost-efficient broadband wireless connectivity. In this paper, we evaluate the performance of a WMN by simulations considering packet delivery ratio (PDR), throughput and delay. For simulations, we used ns-3 simulator and Hybrid Wireless Mesh Protocol (HWMP). We evaluate the performance of the WMN by sending multiple Constant Bit Rate (CBR) flows in the network. The simulation results show that for higher values of transmission rate and 30 connections, the delay and jitter increased very much, so the real-time applications, like video streaming, become difficult.
