Performance Analysis of IEEE 802.11 DCF under Different Channel Conditions

Wireless local area networks (WLANs) based on IEEE 802.11 Distributed Coordination Function (DCF) have been widely used in many industry. This paper mainly analyzes the system performance of IEEE 802.11 DCF under different channel conditions. Firstly, the performance of the system with hidden nodes and without hidden nodes are compared. Then we analyze the performance of system with saturated and unsaturated. Finally, the research methods of IEEE 802.11 DCF are analyzed.
