| Abstract(in English) | In this paper, we present a serious degradation problem with positioning accuracy that occurs when applying wireless LAN-based positioning systems to a tunnel construction site and propose a correction method to solve the problem. The degradation is due to considerable time variation in the received signal strength. In order to mitigate the impact of the time variation, the proposed method corrects the measured signal strength. It is designed for two localization methods: i.e., location fingerprinting and multi-lateration. Furthermore, we evaluate the effectiveness of the proposed method by experiments at an actual tunnel construction site. From the results, we confirm that location fingerprinting with the proposed correction can improve the successful ratio by 5.4% and the average error by 28%, as compared to that without the correction. Moreover, as for multi-lateration with the correction, the average error is reduced by 37%. |
