Abstract [en]

Wireless Local Area Networks (WLANs) are faced with the presence of hid­  den terminals and the possibility of capture when operating in multipath radio  channels. These phenomena complicate both their design and performance anal­  ysis. This paper considers the performance of wireless LANs with Carrier Sense  Multiple Access with Collision Avoidance (CSMA/CA) protocol in fading chan­  nels. 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 chan­  nels affect the system performance and especially for mobile terminals far away  from the access point thus creating unfariness within the system.
