摘要 提出一种无线传感器网络节点的人工势场模型,将相邻节点间的关系虚拟成节点间的虚拟力和虚拟势场.并针对该模型提出一种迭代定位算法,该算法通过计算节点的位移、速度和加速度,给节点定位.理论分析和仿真结果表明,在规则网络中定位误差较小,最优情况下误差可以小于5%,在非规则网络中仍可达到较好的定位精度. This paper proposed an artificial potential field model in wireless sensor networks, turning the connection between neighbor nodes into virtual force and virtual potential field. And proposed an iterative localization algorithm based on this model. It calculated the displacement, velocity and acceleration to localize the nodes. We show by both theoretical analysis and simulations that our algorithm can get low localization errors in regular networks which are less than 5 % in good condition and can get low localization in both irregular networks.
