摘　　要：对近年来无线传感器网络MAC协议的最新研究进展进行了分析和讨论。针对SMAC、TMAC和DMAC三种比较典型MAC协议的机制和特点,从能量有效性、实时性和网络吞吐量等几个方面对协议的性能进行了比较、仿真和分析,指出其各自的优缺点及适应范围,并对它们的应用前景和进一步的研究方向提出有益的建议。This paper analyzes and discusses the recent study on Media Access Control （MAC）protocols for Wireless Sensor Networks （WSN）. For three types of representative MAC protocols such as SMAC, TMAC and DMAC, of which the characteristic mechanisms are described through many sketch maps, this paper presents performance comparison, simulation and analysis from energy-effectiveness, latency and throughput on networks for these MAC protocols and points out theirs advantages and disadvantages and their application range. Finally, some suggestions for future application and research are given for each protocol.
