摘　　要：提出了一种新的低能耗无线传感器网络MAC协议。在802.15.4算法的基础上,对二进制退避算法进行了改进,引入快速退避机制和自适应调整竞争窗口机制,并采用多信道功率控制机制来降低网络能耗。仿真表明,该MAC算法达到了应有的效果。A new low-power wireless sensor network MAC protocol was proposed. In order to reduce the energy consumption of the net- work, the binary exponential backoff algorithm on the basis of the IEEE 802.15.4 MAC protocol was improved, and the fast back off mechanism and the adaptive adjustment competition window mechanism were introduced. Muhi-channel power control mechanism was adopted to reduce energy consumption. Simulation shows that the MAC protocol can achieve the desired effects.
