| 摘 要： | 针对传感器网络在军事领域的应用。本文提出一种适用于战场监视系统的三维无锚点自定位算法。该算法首先对布撒后的全网节点进行不基于地理信息的分簇算法，缩短了全网坐标建立的启动时间。当簇头节点能量将消耗尽时，再进行基于地理信息的分簇算法更新簇头节点。采用OFDM测距方法后，减小了节点间的测距误差。仿真实验表明，传感器网络鲁棒性较高，在区域为400m×400m×50m的三维空间内，随机放置200个节点，其平均定位误差为0.64%，满足战场传感器监视系统的要求。

| Abstract: | A novel anchor-free positioning algorithm is proposed for three dimensional wireless networks,which is used for wireless sensor networks in military field.This paper proposes a three-dimensional localization anchor-free positioning algorithm based on multidimensional scaling.Firstly,the cluster algorithm not based on geography information has been enforced after networks setting,which abbreviates setup time of networks for sensor coordinate.Secondly,the cluster algorithm based on geography information has b... |
