Abstract :
An analytical study is presented of the effectiveness of linear contention window adjustment combined with a long slot duration in the collision avoidance procedures of wireless LAN protocols. A long collision avoidance slot (CAS) duration that includes the beginning of the CTS frame deals with collisions caused by hidden stations. Results indicate that linear backoff minimises empty CASs and reaches a throughput performance very close to maximum. Maximum throughput results obtained by differentiating the throughput equation are compared with similar results in the literature for the IEEE 802.11 protocol.
