Study of Medium Access Control protocol based on adaptive backoff window in wireless sensor network

Wireless sensor networks have been widely used in many areas, and the network channel allocation depends on the Medium Access Control (MAC) protocol, so, it is critical to the performance of wireless sensor networks (WSN). A new MAC protocol (R-MAC protocol) is proposed by combining two thoughts of adaptive backoff window and forecasting data flow according to the node's length of queue based on the sensor MAC(S-MAC). And simulation results indicate that R-MAC is suited to dynamic network traffic conditions and is superior to S-MAC in energy consumption, throughput and delay in star and mesh network.
