摘要
提出了一种基于锚节点功率调节的加权质心定位算法,通过锚节点的功率调节确定各个锚节点对于未知节点的影响力因子,并将其作为权重计算未知节点的位置,体现了不同锚节点为未知节点位置计算结果的影响.仿真表明,该算法减小了节点的平均定位误差,是一种适合于无线传感器网络的定位方法.
This paper presents a kind of weighted centroid localization algorithm based on anchor power adjustment, this algorithm determines the influence factors of different anchors through power adjustment of the anchors and uses the influence factors as the weights to calculating the position of the unknown node which influences the result of the position unknown node. Simulation demonstrate that this algorithm is able to reduce the average error of the localizatl＊on and it is fit for Wireless Sensor Networks.
