摘　　要：针对Leach协议能耗不均和能量利用率不高的缺陷,提出并实现了基于"轮班"工作机制的多跳聚类协议MCPS。该协议在考虑节点通信代价的同时综合了负载平衡和降低冗余数据的思想,有效地改进了Leach协议的不足,提升了网络性能。仿真实验表明,MCPS协议的网络生命周期、能量有效利用率均明显优于经典分簇协议Leach。To the question of Leach,such as uneven energy-consumption and low energy utilization rate,a multi-hop clustering protocol based on shiftwork for WSN（MCPS）is proposed and implemented.By taking into account communication costs of different nodes,and integrating load balancing with the idea of reducing redundant data simultaneously,MCPS improves the lack of Leach and the network performance effectively.Simulation results show that the network lifetime and energy utilization rate of MCPS gain a greater performance than the classical clustering protocol Leach.
