| 摘 要： | 无线传感器网络节点定位至关重要,有着广泛的应用前景.在传统的DV-Hop定位算法的基础上,提出了一种基于跳数比值的定位改进算法.该算法用跳数比值替代距离比值,并在单跳距离中引入RSSI进一步精确跳数比值,根据节点间的几何关系估算节点位置,提高了定位精度,减少了定位过程中的能量消耗.仿真结果表明,该算法比DV-Hop定位算法拥有更好的定位精度和定位鲁棒性.

| Abstract: | In wireless sensor networks,the node-localization is vital and promising to a wide scope of applications.Based on the characteristics of DV-Hop in WSN,an improved scheme for this typical range-free localization algorithm in wireless sensor network is proposed.The main principle of the improved scheme is to introduce ratio of hop as ratio of distance in the third phase of localization,then estimates locations of unknown nodes in the geometrical method.In addition,the introduced RSSI makes ratio of hop more a... |
