摘　　要：针对基于移动信标的传感器节点定位问题,提出一种基于在线决策的移动信标动态路径规划方法。针对以往算法大都只适用于节点均匀分布的局限,该方法用移动信标不断获取两跳范围内的未定位节点数目,并向最大覆盖未定位节点方向移动,不需要网络先验信息,即可实现路径的优化。仿真结果表明:与传统方法相比,该方法无需网络的先验信息,在移动路径长度上具有明显优越性,减少了信标的能量消耗,更适用于户外部署的大规模传感器网络。In order to solve the problem of the mobile beacon based node localization,a dynamic path planning scheme was proposed according to online decision-making.The former schemes have such limitations that they are only suitable for the uniform distribution of node,but this scheme can make the mobile beacon acquire the number of unlocated nodes in the two-hop area and move to the maximum coverage of unlocated nodes.Thus,the path can be optimized without the help of the network topology.The simulation results show that the proposed scheme has obvious advantage in reducing the energy consumption compared with present algorithm and thus is more suitable for the large WSN deployed outdoors.
