| 摘 要： | 提出了一种基于移动信标的辅助定位方法,该方法采用三重覆盖思想确定虚拟信标点分布,保证未知节点获得足够的定位信息;利用蚁群算法获取遍历这些虚拟信标点的最优路径;提出了基于迭代优化算法的虚拟信标点滤波方法.通过对虚拟信标点个数、遍历路径长度、传感器通信距离和定位误差等参数分别进行仿真分析.结果表明,该定位方法在定位精度、定位覆盖率和能量消耗等方面具有一定的优越性.

| Abstract: | A mobile beacon assistant localization method was proposed.In this method,firstly,the number and positions of the virtual beacons were determined according to 3-coverage idea,so sufficient localization information could be obtained for each unknown node;and then,the ant colony algorithm(ACA) was applied to the positions sequence so as to get the optimal path touring it;further,a virtual beacon filter method was presented based on iterative optimization algorithm to improve location accuracy.The simulations ... |
