Queueing Analysis of IEEE 802.11 MAC Protocol in Wireless LAN

In this paper, we present the performance analysis of IEEE 802.11 MAC(Medium Access Control) protocol by investigating the queue dynamics of a wireless station based on the general probability distribution of packet sizes. We use the MMPP(Markov Modulated Poison Process) as the input traffic model well describing the bursty nature of Internet traffic. Thus we have the MMPP/G/1/K queueing model with the MAC layer service time to analyze the throughput and the delay performance of IEEE 802.11 MAC protocol in wireless LAN.We take some numerical examples for the queue dynamics including the mean packet delay and the packet blocking probability.
