摘要： 为了设计能量利用效率更高的无线传感网簇头轮换策略，建立了竞争式簇头轮换的能耗分析模型，分析了数据收集与簇头轮换的能耗比例，提出了基于调度的簇头轮换策略，以消除簇头轮换造成的能耗开销.仿真结果表明，基于调度的簇头轮换策略明显改善了簇内的能量使用效率和能耗均衡性.

Abstract: To design a more energyefficient cluster head rotation (CHR) strategy for wireless sensor networks, this paper built an analytical model for the energy consumption of contentionbased CHR, analyzed the energy consumption ratio between data gathering and CHR, and proposed a schedulebased CHR, which could remove the energy consumption in CHR. The simulation results show that the schedulebased CHR obviously improves energy efficiency and energy consumption balance in the cluster.

Key words: wireless sensor networks, clustering, clusterhead rotation (CHR), energy efficiency
