Adaptive Reservation-Assisted Collision Resolution Protocol for Wireless Local Area Networks

Free registration required

Executive Summary

In conventional IEEE 802.11 medium access control protocol, the distributed coordination function is designed for the Wireless Stations (WSs) to perform channel contention within the Wireless Local Area Networks (WLANs). Packet collision is considered one of the major issues within this type of contention-based scheme, which can severely degrade the network performance for the WLANs. Research work has been conducted to modify the random backoff mechanism in order to alleviate the packet collision problem while the WSs are contending for channel access. However, most of the existing work can only provide limited throughput enhancement under specific number of WSs within the network.
