Abstract

The channel throughput and packet delay of wireless MAC (medium access control) protocols with Rayleigh fading, shadowing, and capture effect are analyzed. We consider CSMA/CA (carrier sense multiple access/collision avoidance) protocols as the wireless MAC protocols, since CSMA/CA protocols are based on the standard for wireless LANs (local area networks) IEEE 802.11. We analyze the channel throughput and packet delay for three types of CSMA/CA protocols; Basic CSMA/CA, stop-and wait CSMA/CA and 4-way handshake CSMA/CA. We calculate the capture probability of an AP (access point) in a channel with Rayleigh fading, shadowing and near-far effects, and we derive the throughput and packet delay for the various protocols. We have found that the 4-way handshake CSMA/CA protocol is superior to the other CSMA/CA protocols in high traffic load
