Room-Level Indoor Localization Based on Wi-Fi Signals

摘要

This paper deals with the indoor localization using Wi-Fi networks. It reacts to the increasing trend in smart devices containing a large number of sensors and modules. The work deals with the use of a Wi-Fi module and a camera. The Android application which uses these modules for the localization and acquisition of fingerprints of wireless networks was created. The application consists of a client and a server side. The approach suggested enables a mobile device to be localized in a building for which a database with fingerprints of wireless networks is created. The application suggested can be used for every building provided that the following conditions are fulfilled; QR codes or other unique visual tags are distributed, the map of the building is available and the fingerprints of wireless networks are captured.
