摘要
目前的室内定位系统还存在很多问题,如:系统成本高、定位精度低、不能适应室内环境的多变性等,这些问题也成为了现阶段室内定位技术研究的热点。基于RSSI的定位技术是解决这些问题的有效途径之一。围绕RSSI定位技术,从RSSI的基本原理入手,分析了RSSI实现定位过程中所用的算法,比较它们的优缺点,并对现阶段室内定位技术所面临的难点问题进行分析总结。
The current indoor positioning system still exists many problems, such as high system cost, low precision, complex and changeable indoor environment, etc., these problems become the focus of indoor positioning technology research at present stage.RSSI based positioning technology is one of the effective ways to solve these problems. Based on RSSI localization technology,this paper starts with the basic principles of RSSI, analyzes the algorithms used in the localization process of RSSI, compares their advantages and disadvantages, and the problems of indoor positioning technology are analyzed and summarized.
