摘要

In recent year, the popularity of WLAN(Wireless Local Area Network) has generated much interests on performance improvement and analysis of the IEEE 802.11 protocol. In this paper, we analyze two medium access methods of the IEEE 802.11 MAC protocol by investigating the MAC layer packet service times when arrival packet sizes have a general probability distribution. We use the M/G/1/K queueing model to investigate the performance of IEEE 802.11 MAC protocol in wireless LAN. We compare the performance of Basic method with that of RTS/CTS method. We take some numerical examples for the system throughput and the queue dynamics including the mean packet delay and packet blocking probability.
