摘　　要：针对随机部署的无线传感器节点,提出一种节点移动方案。将节点移动划分成若干个过程进行,在每个移动过程中根据平衡距离和位置关系进行节点移动,使聚集在一起的节点分散开,实现对监测区域的最大覆盖。由于节点间平衡距离逐渐增大,因此在每个移动过程中节点的移动距离均较小,减少了节点移动距离总和。仿真结果表明,该算法在保证覆盖效果的基础上,降低节点的总移动距离。This paper presents a node movement scheme aiming at the wireless sensor network nodes which are randomly de-ployed. The node movement is divided into several processes, in each movement process according to the balance distance and loca-tion relations move nodes to separate the aggregate nodes and achieve the maximum coverage of the monitoring area. Because of gradually increasing the balance distance between nodes, in each movement process the nodes moving distance is small and reduce the sum of the nodes movement distance. The simulation result shows this algorithm ensures the effect of coverage on the basis of reducing sum of the nodes movement distance.
