具有能量补给的无线传感器网络分簇路由算法
Clustering Routing Algorithm for Wireless Sensor Networks with Power Harvesting
【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.
