摘　　要：传感器网络中如何对节点能量进行优化使用是传感器网络应用中的关键技术之一。对低功耗自适应分簇协议进行改进,基于各节点的覆盖值不同,调整节点被选为簇头的概率,使簇头的分布更加合理。通过仿真结果表明:改进的协议可以节省传感器网络的能量消耗,从而延长网络生命周期。In wireless sensor networks one of the key problems is how to make maximal use of energy. The improvement of the low- energy adaptive clustering hierarchy routing protocol, which changed the probabilities of nodes to be cluster due to the coverage, made the distribution of clusters more reasonable. The simulation results show that the using of the improved protocol in wireless sensor networks can save the energy consumption efficiently and that the system lifetime is extended.
