In the case of the store, indoor location estimation adopts absolute location estimation techniques using RSSI of Wi-Fi 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. Therefore, an accuracy of location estimation deteriorated by irregular shielding of wireless signals when pedestrians pass through in the store. 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 0.5m against a method only considering static obstructions and our method keeps a constant error regardless of the number of selected BLE beacons. In addition, the average positioning error in the proposed method improved by 0.7m even in the real environment experiment, and we showed the superiority of this method.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"57","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"48","bibliographicIssueDates":{"bibliographicIssueDate":"2019-01-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"1","bibliographicVolumeNumber":"60"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":193882,"updated":"2025-01-19T23:47:19.387148+00:00","links":{}}
