Autonomous Mapping Using RSSI-based Fingerprinting

Abstract: In this paper we present an autonomous method of mapping an indoor location by building an RSSI (Received Signal Strength Indication)-based fingerprint database. We use a robot, a Kinect sensor, a laptop and a WLAN receiver in this project. The Kinect gives the coordinates of the robot; the coordinates are stored in a database. Simultaneously, the WLAN receiver sends the RSSI data to the database. Once this is achieved the robot moves forward and the process is repeated till the entire area is mapped.
