Performance of Wireless LANs in Radio Channels

Wireless Local Area Networks (WLANs) are faced with the presence of hidden terminals and the possibility of capture when operating in multipath radio channels. These phenomena complicate both their design and performance analysis. This paper considers the performance of wireless LANs with Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol in fading channels. To assess the presence of hidden terminals and the possibility of capture, a stochastic channel model between the different stations and between the AP and the stations is used. The system throughput and the average packet delay are evaluated under fading conditions. The obtained results show that fading channels affect the system performance and especially for mobile terminals far away from the access point thus creating unfairness within the system.
