Abstract(in English) | The development of wireless LAN-based positioning technologies has been proceeding to realize indoor location-depended services that require high positioning accuracy. In this paper, we propose an interpolation method of training data for location fingerprinting to reduce the cost required for building the training data. More specifically, a critical problem with location fingerprinting is considerable cost for measuring received signal strengths at every location where the positioning is possible. In the proposed method, a part of the training data is interpolated from data actually observed at several locations using a path loss model considering wall attenuation. Furthermore, to confirm the effectiveness of the proposed method, we examine the performance of location estimation and verify the interpolated data. As compared with a conventional method, the proposed method can improve the positioning accuracy by 15%. |
