Abstract: This paper proposes a localization algorithm based on the beacons moved by geometry.The main idea of this algorithm is to use values of signal strength between unknown nodes and beacons to define the field of the unknown nodes and calculate coordinate of the unknown nodes by geometry way.Experimental results show the error of this algorithm is low,and its calculation is simple so that suitable for all sizes of Wireless Sensor Networks(WSN).

Key words: Wireless Sensor Network(WSN), localization algorithm, signal strength

摘要: 提出了一种信标节点以一定的几何形状进行移动来对未知节点进行定位的算法。利用未知节点到信标节点的信号强度值来确定未知节点所在区域,然后用几何方法计算得到其坐标。实验表明:提出的算法定位精度高,计算简单,适合各种规模的无线传感器网络的节点定位。
