%X Based on the IEEE802.11DCF, a Medium Access Control (MAC) protocol was proposed for wireless ad hoc network. It consisted of two key mechanisms: network adaptive backoff algorithm and congestion feedback mechanism. The main idea of proposed protocol was to schedule packet according to real contention status around the node and network congestion situation. The simulation results show that the proposed scheme can effectively reduce the average end-to-end delay, mitigate packet dropped ratio, and improve fairness of channel access.
