从无线传感器网络的应用研究角度出发,传感器节点位置信息的获得是任何应用的基础本文采用了最小二乘法和极大似然估计法分别对未知节点进行计算的非测距的DV-Hop定位算法实现了对数据进行定位处理,且采用极大似然估计法对未知节点的计算可以获得较高的定位精度。
From the angle of application research of wireless sensor networks, the location of sensor nodes is the basis for any application. In this paper, the non-ranging DV-Hop localization algorithm which uses the least square method and the maximum likelihood estimation method respectively to calculate unknown nodes Realize the data positioning, and the use of maximum likelihood estimation of unknown nodes can be calculated for high positioning accuracy.
