Recently, research of indoor location estimation has been attracting attention for tracking behaviors of human in a store. In the case of the store, indoor location estimation adopts absolute location estimation techniques using RSSI of WiFi or BLE signals from beacons installed in the store. As the RSSI has been influenced by the signal reflection, the diffraction, the shelter and others, an estimated values can cause errors during the process of converting the RSSI values into distances. In this paper, we propose dynamical and optimal beacon selection method to minimize affections of wireless signal shielding by the static and movable obstructions. As the result of a simulation, we found that the average of the location estimation errors using our proposed method is reduced by 1.2m against a method only considering static obstructions and our method keeps a constant error regardless of the number of selected BLE beacons. |
