In this paper analyze the performance of Wireless Local Area Networks (WLANs), it is important to identify what types of network settings can cause bad performance. Low throughput, high packet loss rate, delayed Round Trip Time (RTT) for packets, increased retransmissions, and increased collisions are the main attributes to look for when analyzing poor network performance. The authors use the OPNET Modeler to simulate the RTS/CTS mechanism to evaluate the performance of IEEE 802.11 MAC protocol. They have simulated two scenarios with and without RTS/CTS mechanism enabled on network nodes. They have concluded their findings by comparing the total WLAN retransmissions, data traffic sent/received, WLAN Delay of two scenarios.
