Abstract

In order to analyze the performance of IEEE 802.11 wireless communication protocol, a performance abstract model of IEEE 802.11 protocol was built base on POOSL language and the performance was analyzed qualitatively and quantificationally in ad hoc network and WLAN with AP. During modeling, the protocol was abstracted rationally. Wireless channel was successfully simulated and the two accessing methods of DCF (basic and RTS/CTS) were simulated accurately. By simulating, the effects of related parameters (the number of STAs, CWmin and frame size) on performance of the protocol (valid throughput, average delay and the fairness of upload and download throughput) were analyzed and got the optimist values of the CWmin.
