Wireless Indoor Tracking System

Wireless Indoor Tracking System A wireless indoor tracking system is described in this paper, which can be used to track and locate both moving and static WLAN-enabled devices inside a building. The system is purely software based, which means an advantage for the existing WLAN. No additional hardware and costs are required. Using complex mathematic algorithms, the system determines the locations of the mobile devices according to the received signal strength from visible access points. Taking into account the historical signal strength, the interior structure of the building and available Bluetooth access points, the positioning and tracking accuracy achieved is very optimistic. Experimental results are reported at the end of the paper.
