Abstract
Recently, IEEE 802.11 protocol has been widely implemented in wireless local area networks (WLAN). The primary medium access control (MAC) technique, distributed coordination function (DCF), that specified contention-based medium access mechanism has been widely used to support applications in new regimes. Fully understanding IEEE 802.11 DCF is the focus of this article. This topic has already been discussed by several existing models, however most of them ignored some protocol details.
This thesis is about the problems of existing models with DCF protocol and provides a new model that takes behaviors of the channel and more details into consideration. Based on the proposed model,we perform simple, but rigorously accurate analysis model of saturation extensive performance in WLAN to present our results in the transmitted probability, throughput, and interarrival time. All the findings are verified by Qualnet Simulation to ensure the accuracy and thoroughness of the proposed model.
