Performance evaluation of distributed access scheme in error-prone channel

Abstract

Distributed Coordination Function (DCF) protocol is used for channel access in IEEE 802.11 WLAN. The performance issue of the protocol has provoked a lot of research interest. However, during the previous research work, the impact of retransmissions and bit error ratio on the performance of DCF was not taken into consideration. An analytical model is presented in this paper to evaluate the performance of the scheme in the case of finite retransmissions.
