CRMA: a novel multiple access protocol for power efficient wireless LAN

To improve the binary exponential backoff algorithm (BEB)'s channel throughput of IEEE 802.11 protocol, we propose a novel collision reduced multiple access (CRMA) protocol based on slow contention window decrease mechanism and runtime optimization method. CRMA protocol can record the current backoff stage of the latest successful transmission under the overload network precisely. As a result, it decreases the collision times and improves the channel utilization.
