Indoor Location Estimation Considering Movable Obstruction by Using Multi-Hop Beacon Information

摘要

We can use a lot of services using positioning system. Accordingly, there is a problem about improving indoor positioning accuracy. In this research, by using the mobile terminal (smartphone and tablet) as a kind of beacon, we propose a method that can estimate positions with higher precision in a place with many people than previous ones. We attempt to improve the positioning accuracy by calculating distances between each device with RSSI considering movable obstructions. We experimented in a real environment and applied a proposed method to an environment where we set three BLE beacons and three humans who have mobile devices. As a result, compared with previous methods, the positioning accuracy improved, which showed the superiority of this method.
