| 摘 要： | 提出一种基于加权质心的无线传感器网络移动节点定位算法(WCentriod-M),使其较好地适用于无线传感器网络移动节点定位。算法将采样时间分成若干个时间窗,在节点运动时维护一个过去记录,基于这些历史记录来选择信标节点。利用未知节点接受到的信标节点信号强度的比值作为加权因子,在定位的过程中考虑信标节点的权重。仿真实验表明,该算法具有计算简单、节点能量消耗小、定位精度较高等特点。

| Abstract: | In this paper we present an algorithm of mobile node localization based on weighted Centroid for wireless sensor networks. The proposed method splits the original sampling period of the Centroid algorithm into temporal windows in order to maintain a record of past information during movement. The selection of the anchor nodes is based on the weights of the temporal window. The RSSI ratios received from the anchor nodes are used as weights to determine the position of an unknown node. The results from simula... |
