基于无线局域网接收信号强度分析的混合室内定位方法
Hybrid indoor positioning method based on WLAN RSS analysis
摘要
Abstract
In order to provide abundant indoor location-based services (LBS) , it is crucial to get accurate location in complex and crowded indoor environments. According to the received signal strength (RSS) analysis in wireless local area network (WLAN), hybrid indoor positioning method integrating trilateration and fingerprint is reasonable. Firstly, The RSS database of reference points is established based on the divided grids, and the locations of wireless access points (Aps) are estimated by applying trilateration, then the RSS threshold is set based on the positioning accuracy requirement. During online positioning, according to the number and RSS of wireless Aps accessed by terminal of users, trilateration or fingerprint is selected for calculating position. Experimental results show that the proposed indoor positioning method is effective and stable.关键词
