چکیده
In recent years, position estimation systems using wireless LAN have been actively studied, along with the publication of many contributions. However, most of these location estimation methods require prior knowledge of wireless LAN access point locations. To deploy a location estimation system widely in the real world, it is crucial to develop an efficient pre-acquisition method of wireless LAN access point information. In this paper, we examine three kinds of pre-acquisition methods (gathering information by foot, bicycle, and car) and evaluate them according to the accuracy of the position estimation. Additionally, we present the acquisition performance of the efficient method we are now studying.
