摘　　要：节能是无线传感器网络介质访问控制(MAC)协议的首要目标,综合近年来MAC协议的研究成果,针对S-MAC、T-MAC等几种典型协议进行分析,研究出将拓扑结构控制机制引入MAC协议,可进一步降低能耗。给出了一种基于GAF拓扑控制思想的MAC协议、GS-MAC协议。GS-MAC协议可以降低处于空闲侦听状态的节点数量,是一种高效节能的协议。仿真表明,引入拓扑控制后可以达到进一步节约能耗的目的。Energy-saving design is the primary design objective of wireless sensor networks media access control protocols.The research results of MAC protocol are summarized,and some typical MAC protocols are analyzed such as S-MAC,T-MAC and etc.Studies show that introducing Topology control mechanisms to MAC protocols can reduce energy consumption further,and a new MAC protocol （GS-MAC） is introduced for wireless sensor networks,which can provides an effective mechanism for improving energy efficiencies by reducing the number of idle listening nodes.The simulation results show that energy can be saved further by this protocol.
