中文摘要：

为提高移动信标辅助定位算法的定位精度,避免重复扫描待定位节点,提出了一种使用多个移动信标的定位方法。这些信标在遍历网络时保持一定相对位置关系,使用TDoA技术测距并为未知节点提供距离信息辅助其定位。提出了基于最优覆盖策略的2种移动信标路径规划方法。仿真结果表明,所提出的算法具有较高的定位精度,且所使用的移动路径性能较高。

英文摘要：

To improve the localization precision and avoid scanning unknown nodes repeatedly in mobile beacon assisted localization method,a multi-mobile-beacon assisted localization scheme was proposed.The beacons keep a certain rela-tive position while traversing the network and ranging with TDoA,and provide information to unknown nodes to esti-mate locations.Two path planning methods based on optimal coverage strategy were introduced.Simulation results show that the proposed scheme and paths perform well.
