摘要
为提高微网无线传感器网络监测系统中故障定位的精度,提出一种基于反转法的改进DV-Hop算法。设置锚节点使用双通信半径精化跳数值,使用反转法修正节点的估计坐标,利用与跳数值相关的动态权值进一步修正得到未知节点最终的坐标。仿真结果表明,改进算法与原始DV-Hop算法及其它算法相比,有较低的误差,可以更好应用于微网故障定位。
To improve the accuracy of fault location in micro-grid wireless sensor network monitoring system,an improved DVHop algorithm with inversion method was proposed.Dual communication radius was employed to refine the hop count.Inversion method was utilized to correct the estimation coordinates of unknown nodes.Dynamic weight value associated with the hop was used to do further revision.Results of simulation example demonstrate the better effectiveness of the proposed algorithm on fault location than the traditional DV-Hop algorithm and other algorithms.
