摘　　要：针对无线传感器网络(WSN)中的网络生命周期问题,提出一种基于节点能量消耗(EC)的改进型稳定选举协议(EC-SEP).在二级能量异构网络中,EC-SEP协议将节点能耗因子与传统SEP簇头选举机制相结合,每一轮中更新节点的簇头选举概率,提高剩余能量较高的节点被选举为簇头的可能性,以此来均衡节点的能量消耗,提高网络的生命周期和吞吐量.将EC-SEP与LEACH、SEP、ESEP协议进行比较,结果表明,EC-SEP协议在网络稳定性和吞吐量方面具有更好的性能.For the issue of network lifetime of wireless sensor network（WSN）,a node Energy Consumption based Stability Election Protocol（EC-SEP）is proposed.In two level heterogeneity network,EC-SEP combines node energy consumption rate with traditional SEP cluster head election mechanism,and update node election probabilities in each round,therefore increase the election probabilities of nodes with higher residual energy,so as to balance node energy consumption as well as increase lifetime and throughput of network.Experimental results illustrate that,compared with LEACH,SEP and ESEP protocol,EC-SEP may provide better performance on network stability and throughput.
