| 摘 要： | 针对DV-hop算法定位精度低的问题,本文分析了节点间的位置拓扑关系对定位精度的影响,提出了一种基于局部信标选择的定位算法(RBS-DV-hop)。该算法权衡了定位精度和计算复杂度,从三方面寻找局部最优的信标节点组,包括信标节点的共线度、未知节点与信标节点的跳数以及信标节点相对于未知节点的分布。仿真结果表明,改进后的算法明显提高了定位精度和稳定性,为合理选择信标节点组进行定位提供了一种方法。

| Abstract: | After analyzing the topological relationship between nodes,this paper proposed a new localization algorithm (RBS-DV-hop) based on regional beacon selection to solve the problem of low localization accuracy in traditional DV-hop. The beacon selection performs around the unknown node by making a tradeoff between accuracy and computational workload,the procedure includes the colinearity of beacons,the hops between unknown node and beacon,the beacon spread relative to unknown node. The experiment and simulation... |
