WLAN指纹定位中AP选择策略研究
Research on AP Selection Strategy Based on WLAN Fingerprint Positioning
摘要
Abstract
The fingerprint positioning technology based on WLAN (Wireless Local Area Network) is the hotspot in the field of indoor positioning at present. With the popularity of WLAN in public places such as shopping malls,universities and office buildings,there are many available terminal AP (Access Point) nodes because of the high density of AP distribution,which provide good foundation for WLAN-based positioning. However,since the signal instability caused by frequently blocking and occasional failure of AP nodes,optimal positioning result cannot be guaranteed in the case of using all available AP nodes. The selection algorithm of AP nodes is more deman-ding in such a case. In this paper,four novel AP selection algorithms were proposed. The real-world experiments were carried out to veri-fy the proposed algorithms. The result shows that the selection of AP is essential and necessary in terms of achieving better positioning performance. Moreover,appropriate AP selection algorithm can effectively improve the positioning accuracy.关键词
