摘　　要：无线传感器网络中,节点能量及其消耗率影响网络的稳定性和整个网络的生命周期。针对传感器网络能量有限的特点,提出了一种基于分簇的节能路由算法。通过用改进的四色算法选举簇头,并建立网络逻辑簇结构,使网络簇的逻辑结构更加合理。以节能为目的,增加了能量信息维护和节点能量保护。仿真实验表明了该算法的有效性。Wireless sensor networks, the energy and drain rate of mobile node can influence the networks lifetime and stability. A new cluster-based routing protocol for energy-limited is proposed. The cluster head is selected through an improved four color algorithm to build up the logical structure of the network, it can significantly less overlap. For a purpose of saving energy, add energy information maintenance and node energy protect. The performance of the algorithm is shown by simulation.
