WSN中基于LEACH-DCHS协议的簇维护算法

节能是无线传感器网络设计中的一个重要的目标，而路由算法对无线传感器网络的能量消耗有着重要的影响，所以提高路由算法的有效性，以减少网络中的能量消耗是非常必要的。在原LEACH-DCHS算法的基础上，提出了LEACH-DCHS CM（LEACH-DCHS Cluster Maintenance）算法。LEACH-DCHS CM通过延长网络稳定通信时间，同时兼顾网络中节点能量的均匀消耗，来达到节省能量的目的。仿真分析表明，新的算法在节能和信息传输的实时性方面较已有算法有很大的提高。

Saving energy is an important goal in the designation of wireless sensor networks，and routing algorithm has an important impact on energy consumption for wireless sensor networks.Therefore，improving the energy efficiency of routing algorithm to reduce energy consumption in the network is very necessary.LEACH-DCHS CM（LEACH-DCHS Cluster Maintenance） algorithm based on LEACH-DCHS algorithm is proposed in this paper.By prolonging the steady-state phase time and retaining the concept of round in the original algorithm，the new algorithm achieves the purpose of saving energy ultimately.Simulation results validate the energy efficiency of LEACH-DCHS CM algorithm.
