摘要

提出了一种全新的RF定位估测方法。测量了在锚节点中的未知节点收到的信号强度

然后转换信号强度的信息为距离的估测。使用这些估测得到了一种未知节点的概率分配模型并终于找到了概率最大时候的位置

由此作为结果。实验中采用了Matlab作为仿真工具

而所得到的结果相比先前的定位方法有一定的优势。

Abstract

A novel estimation method based on radio frequency（RF） localization is presented.The received signal strength（RSS） from unknown node at the anchor nodes is measured

and the RSS information is transformed into distance estimations.By using these estimations

a probability distribution model of the unknown node is got and location when the probability is maximum is found as the destination.Using Matlab as simulation tool

the result shows that compared with previous methods

this method is competitive.
