基于RSSI的三维加权质心定位研究

摘要

本文提出了一种基于接收信号强度值（Received Signal Strength Indication, RSSI）的三维加权质心定位方法，并在其中引入通信半径的概念，提出两个不同的算法，同时在算法中加以修正。通过在一定范围的空间区域中的仿真实验表明，本文提出的算法具有很高的定位精度和广泛的适用范围。%This paper introduces a RSSI-oriented 3D weighed centroid localization method, while bringing in the concept of communication radius. It proposed two different algorithms, with some revisions added on. It is shown by simulation experiments in a spatial region of certain size that the algorithms proposed in this thesis has high localization precision and wide applications.
