摘　　要：路径规划方案在无线传感器网络的节点部署中有着非常重要的作用。为了克服锚节点共线问题和减少定位时间,在研究已有的移动锚节点路径规划方案的基础上,提出了一种"Z"曲线路径规划方案。仿真实验表明,所提出的"Z"曲线路径规划方案与已有的4种路径规划方案相比,克服了锚节点共线问题,减少了定位时间,提高了节点定位精度。Path planning scheme is essential in the node deployment of wireless sensor networks(WSNs). In order to overcome the collinear beacons problem and reduce positioning time, based on the existing mobile beacon path planning schemes, this paper proposes a path planning scheme based on "Z"curve. Simulation results show that compared with four existing path planning schemes,the proposed path planning scheme based on"Z"overcomes the collinear beacons problem,reduces positioning time, and improves the localization accuracy.
