| 摘 要： | 针对部署在三维空间的无线传感器网络,提出了一种传感器节点自身定位方法LIE-3D。该算法通过判断锚节点对传感器节点可能所在网格的得票数,筛选出可能的位置区域,并最终计算这些区域交集部分的质心,作为待定位节点的位置。理论分析及仿真实验结果均表明:LIE-3D定位方法无需复杂的测距设备和昂贵的外部设施,且通信协议相对简单,对网络拓扑具有一定的鲁棒性,因此是一种低成本、低功耗的无线传感器网络三维自身定位方法。

| Abstract: | A novel three-dimensional(3 D)self-localization scheme LIE-3 D was presented for wireless sensor networks(WSNs).The target sensor performed LIE-3 D test to judge the vote of the grid sereen the possible location areas,and finally calculate the mass center of the intersection part of these areas as the location of the node to be positioned.Theoretical analysis and experimental results show that LIE-3 D depends on no ranging measures or global infrastructure,and presents a low-cost solution for self-localizat... |
