Development of Bluetooth based indoor positioning application

This paper presents an Android application that is capable for proximity based indoor localization using Bluetooth RSSI. Proximity based localization can be useful for finding well recognizable objects or areas within building. The goal of the system is to locate offices and people in office buildings. The presented algorithm estimates the distance between client and beacon, based on RSSI values and Log-Distance Path Loss Model. Application was tested in a three story building and experimental results demonstrate the applicability of the localization algorithm. The application estimated the position correctly in 88% of the test cases.
