摘要 无线传感器网络的MAC协议可以利用监听/睡眠周期节约能源。对监听/睡眠周期和网络性能的关系进行了分析,研究了自适应的MAC协议及改进算法,通过动态调整节点唤醒的周期和相位来适应网络的动态变化。仿真表明改进后的协议可以减少时延,提高吞吐量和能源效率。 MAC protocols for wireless sensor networks（WSN） can exploit listen/sleep cycles to save energy.The relationship of the listen/sleep cycles and network performances is analyzed.An adaptive schedule medium access control（AS-MAC） for WSN is researched,which can adjust the wake-up cycle and the phase when traffic is changing dynamically.Simulations validate that the protocol can decrease the latency,improve the throughput and energy efficiency when traffic is dynamic.
