摘要： 提出一种具有能量补给的无线传感器网络分簇路由算法PHC。在PHC中，传感器节点通过周围环境获取能量补给。PHC综合考虑节点自身的能量起伏变化以及能量补给水平，修正了现有的簇头选择机制和非簇头节点的归属机制，使能量消耗平均分配到整个网络中。通过仿真表明，PHC在考虑了能量补给的同时，改善了无线传感器网络中能量消耗的均衡性，延长了网络的生命周期，网络中最终存活节点和整体残留能量提高了20%。

Abstract: This paper proposes a new routing algorithm named Power-Harvesting Clustering(PHC), in which the nodes may harvest power from the ambience. PHC modifies the cluster-head selection algorithm and non-cluster-head attribution algorithm according to the node’s power-level, power-harvest level, and the distance between the cluster-head and sink node. The simulation results prove that PHC can equilibrate the depletion of energy in WSN, and prolong the network’s lifetime when compared with LEACH in vibration power harvesting.
