摘要 无线传感器网络分簇协议通常假定网络是同构的,即网络中所有节点具有相同的初始能量,这些协议不能充分利用异构网的特点。提出了一种适合于异构网的分布式分簇协议(EHCP),该协议优先选择剩余能量较多的节点作为簇首以平衡节点的能量,并在簇间采用多跳通信以节省能量。仿真实验结果表明:与同类协议相比,EHCP协议能显著地延长网络稳定工作的时间,具有良好的性能。 Wireless sensor networks clustering protocols usually assume that all the nodes are equipped with the same amount of initial energy and as a result,they can not take full advantage of the presence of node heterogeneity.This paper presents a distributed clustering protocol suitable for heterogeneous wireless sensor networks （EHCP）.It preferentially chooses those nodes with more energy as the cluster heads to balance the energy of nodes,and utilizes multi-hop transmission among clusters to save the energy.Simulation results show that EHCP can obviously prolong stability period of networks and has perfect performance compared to similar protocols.
