摘要

WLAN-based positioning methods are popular because they can be deployed anywhere without additional infrastructure investment. Among them, positioning based on fingerprint radiomap has been widely studied in terms of fingerprint radiomap construction and device position estimation in offline (training) and online (positioning) phase, respectively. This paper presents simple and practical WLAN-based positioning method in which WLAN access point (AP) location database is considered as a radiomap to reduce its size and radiomap is updated in unsupervised manner in online (positioning) phase to maintain up-to-date without additional construction cost. Experiments carried out in smartphone device and shows effectiveness of the proposed methods.
