摘　　要：优化传感器媒介访问控制(S-MAC)协议以减少网络能量消耗和数据延迟,已成为无线传感器网络(WSN)亟待解决的问题。在S-MAC协议原有周期不变的情况下,根据通信流量变化改变活动时间,以减少能量损耗,同时在NS-2仿真平台采用MILD算法减少节点间不公平竞争现象,并建立了优化后的NS-MAC协议。实验结果表明,NS-MAC协议在能量损耗与延时性能上较S-MAC协议效果更佳,也更加符合WSN的MAC协议节能设计原则。Optimizing the sensor media access control(S-MAC)protocol to reduce network energy consumption and data delay has become an urgent problem for wireless sensor networks(WSN).In this paper,under the condition that the original cycle length of the S-MAC protocol stays unchanged,the activity time is changed according to the change of the communication traffic so as to reduce the energy loss.At the same time,the MILD algorithm is used in the simulation platform NS-2 to reduce unfair competition among nodes,and an optimized NS-MAC protocol is established.Experimental results show that the NS-MAC protocol has lower energy loss and better delay performance than that of the S-MAC protocol,and it is more suitable in line with the design principles of the energy-saving WSN MAC protocol.
