| 摘 要： | 节点定位是无线传感器网络中的重要应用之一.为了有效抑制各种因素对无线传感器节点定位精度的影响,以三边定位算法为基础,提出了一种基于误差校正的定位算法.该算法通过测量信标节点之间的距离,获得信标节点RSSI值测量误差和网络的定位误差,并对误差进行补偿,从而提高整个网络的定位精度.实验结果显示,该算法能明显提高定位精度和稳定性,具有普遍应用意义.

| Abstract: | Localization of nodes is an important application of wireless sensor networks.In order to suppress effectively the effects of manifold factors to WSN node localization precision,a localization algorithm based on error correction is provided.Errors of RSSI measurement and network location can be got by measuring the distance between beacon nodes,thus the positioning accuracy of entire network can be improved by error compensation.Tests show that this algorithm has the advantage of precision and stabilization... |
