Indoor/outdoor determination method using various sensors for the power saving of terminals in Geo-fencing

Recently, various services using the location in- formation are developed with the wide spread of smartphones. Geo-fencing is one of the services. In Geo-fencing services, terminals automatically carry out the some processing associ- ated with the virtual border when they detect that themselves passes the border. However, it is a problem that power saving of Geo-fencing service covering over indoors and outdoors with high accuracy. In this paper, we propose indoor/outdoor estimation method using various types of sensors with small power consumption. The results of the evaluation experiment show that the proposed method can estimate the movement in indoor and outdoor with 82.14% accuracy, and this method is an effective means for indoor and outdoor Geo-fencing ser- vice.
