摘要: 为节约节点能耗,获得更长的生命期,很多无线传感网络的MAC层协议引入了周期睡眠方式。在节点周期睡眠时,如何实现节点间的通信是研究的焦点。基于睡眠唤醒机制的异步MAC协议是解决方法之一,其在低负载时具有较好的节能效果。在此类MAC协议基础上,针对数据汇聚型应用场合进行改进。通过分析和实验表明,该改进既降低了能耗,又改善了延时性能。

Abstract: A lot of Wireless Sensor Network(WSN) MAC protocols use periodical sleep to save energy, gaining long lifetime. How to realize the communication between the nodes when using the periodical sleep mode is the focus research. An asynchronous MAC based on wake is a solution which achieves low energy consumption when applied to the sporadic traffic occasion. This paper improves the MAC protocol. The analysis and experiment shows that the modification reduces the energy consumption and improves the latency performance.

Key words: Wireless Sensor Network(WSN), energy consumption, latency, periodical sleep
