| 摘 要： | 提出一种利用移动节点的无需测距的无线传感器网络定位算法.该算法中,移动节点以垂直路径两次穿过未知节点通信半径范围,从而获得通信区域边界附近多个航标位置；航标点连线的中垂线形成几何限制区域,该区域中心即为未知节点的估计位置.与其它基于几何限制区域的算法相比,本算法计算复杂度低、定位精度高.仿真实验结果显示本算法相比于其它算法,定位精度提高10％～40％不等.

| Abstract: | A range-free localization algorithm using mobile nodes for wireless sensor network(WSN) is proposed.In this algorithm,a mobile node travels across the communication range of the unknown node in two vertical paths,and gets some beacon localizations near the border of communication range.A geometric constraint area is formed by the perpendicular bisector of the segments connecting beacon points.The center of the area is the estimated location of the unknown node. Comparing with other methods based on geometri... |
