Abstract:
Fingerprinting requires sensor data map to estimate a user’s location by comparing the map with sensor data of the user’s device. Although it is assumed that the sensor data does not change, it is considered that the premise is not stable in the geomagnetic fingerprinting near a large electric current flows or an electric device utilizing electromagnetism generating a magnetic field. In this paper, we report the result of fixed point observation of geomagnetism at the place where change is likely to occur in the building of university.
