摘要
无线传感器网络的关键问题是实现节点的精确定位。为了解决基于RSSI的无线传感器网络三角形质心定位算法在有些情况不适用的问题,本文提出一种新型的基于RSSI的精确室内定位算法,此算法提出了虚拟信标节点的概念并用此来修正未知节点位置。实验表明,该算法具有较高的定位精度,能满足大多数的应用场合,具有一定的实用价值。
Localization of nodes is a fundamental issue in wireless sensor network.RSSI-based Triangle and Centroid Location sometimes does not work.In order to solve the problem,the paper proposes a new localization algorithm—RSSI-based Accurate Indoor Localization Algorithm（RBAILA）.The algorithm advance the concept of the virtual beacon nodes and use them to refine the location of the unknown node.Experiments prove that this algorithm can obviously improve the location accuracy and it can be applied to many applications.
