摘要/Abstract

摘要： 为提高WSN定位精度,提出一种带定向天线的移动锚节点定位算法。首先对WSN进行分层,锚节点可沿x轴和分层线移动实现对未知节点的遍历,在移动过程中等间隔距离旋转定向广播位置信息,未知节点根据接收到的锚节点坐标、方位角等信息确定自身位置。定位算法简单,无需测距,完全使用锚节点信息实现定位,仿真结果表明,该算法比典型的采用单个移动锚节点的SLWL算法具有更高的定位精度和定位稳定性。

Abstract: A localization algorithm for WSN using one mobile anchor with directional antenna was proposed to improve positioning accuracy．The network was divided into several layers,and then anchor node moved along the x axis and layer boundary to traverse all unknown nodes．At intervals of the same distance,the anchor node directed broadcast position information in the process of moving．The unknown nodes according to the anchor node coordinate and azimuth information to determine its position．The simulation results show that,the algorithm has higher accuracy than the typical SLWL algorithm.
