摘　　要：提出了一种基于映射扩散的无线传感器网络节点定位算法,适用于规模较大、参考节点较少的无线传感器网络.该算法在传感器网络中首先随机选择一个节点作为"起始节点",然后根据扩散算法选择3个"一级节点",然后以每个一级节点为中心,逐级外推,直至覆盖网络中的所有节点.仿真结果证明,该算法可以快速准确进行定位,可降低和均衡所有节点的能耗,提高定位精度.A map diffusion based localization algorithm is proposed for wireless sensor network localization,which is suitable for large scale and few anchors network.Map diffusion localization algorithm select a "start node" randomly in first phase,then according to diffusion algorithm to select three "1 level" nodes which are used as centers to mapping the next level nodes gradually until all nodes are covered.Simulation results demonstrate that map diffusion based localization algorithm can localized the node accur...
