基于邻居节点位置的无线传感网休眠算法
A Sleeping Algorithm for Wireless Sensor Network Based on Location of Neighbors
摘要
Abstract
In Wireless Sensor Networks ( WSNs) ,nodes are densely deployed,which may increase a number of redundant nodes. Consid-ering the network’ s coverage,a type of sleeping scheduling algorithm is proposed about coverage redundancy. Each node calculates the coverage rate of its sensing area according to the locations of its neighbors nodes. If the coverage rate is beyond the threshold,the node goes into sleeping mode while other sensor nodes remain active. Simulation experiment shows the effectiveness of the algorithm. By sleep-ing redundant nodes in the network,network energy is saved and network life is prolonged. Moreover,compared with other algorithms,the ability of the algorithm to detect redundant nodes is much better. The number of redundant nodes is greatly reduced in the network.关键词
