中文摘要: 在无线传感器网络中,距离无关定位技术得到了人们广泛的关注.在有洞的各向异性网络中,为提高普通结点到信标结点之间距离估计的准确性,提出一种距离无关的动态可靠信标结点定位算法.该算法以不同信标结点对之间最短路径上平均单跳距离差异为基础,得到普通结点的直接可靠参考信标结点集和间接可靠参考信标结点集.然后,从可靠参考信标结点集中选择参考结点对普通结点进行定位.仿真结果表明,与以前算法相比,新算法能降低定位误差.

Abstract:Range-free localization technology in wireless sensor networks is of great current interest for researchers. In order to improve the accuracy of range estimation between the sensors and anchors, we introduced a dynamic reliable anchor-based location discovery algorithm in anisotropic wireless sensor networks with holes, which was range-free. Based on the differences of average distances of one hop along the shortest path between different anchor pairs, sensor nodes managed to get two sets of direct reliable reference anchors and indirect reliable reference anchors. Then sensor nodes were localized by using the reliable reference anchors set. Simulation results show that the positioning error is decreased compared with previous algorithms.
