基于功率控制的无线传感器网络节点定位算法
Localization algorithms based on power control for wireless sensor network
摘要
Abstract
For the field of a large area or the field which doesn’t need exact location,a node localization algorithm was proposed based on power control.With power control technology,three ring containing the unknown node was formed by the three base stations,and by calculating the centroid of the cross-region formed by the three rings location of the unknown node was achieved.Simulation results showed that within a radius of 800 meters,the absolute location error of the algorithm could be smaller than 8 m and the coverage was up to 99%.With the increase of the number of broadcast power level of base station,location accuracy and coverage also improved.The algorithm did not require the deployment of anchor nodes and information exchange between nodes,and was with high practicality.关键词
