| 摘 要： | 在无线传感器网络中,节点的准确定位是具体应用的前提和基础。提出一种基于R S S I的加权质心算法的改进算法,并利用未知节点接收到的来自各个不同锚节点的R S S I值为依据计算加权权值,算法实现更加容易、简单。仿真结果验证了算法的有效性,比传统的质心定位算法的定位精度有较大提高。

| Abstract: | In wireless sensor networks(WSN),the accurate localization of nodes is the base of the specific application.The paper presents an improved weighted centroid localization algorithm based on the RSSI,using the RSSI value of the unknown node received from different anchor nodes to decide the weighted factor.Therefore,the localization algorithm is easier and simpler.The simulation experiments prove that this localization algorithm can obviously improve the localization accuracy compared to the centroid localization algorithm. |
