propose a novel indoor localization method that is robust against failures of Bluetooth Low Energy (BLE) beacons to achieve beacon maintenance cost reduction. The electromagnetic environment often changes due to beacon failures such as lost or weakened signals and this causes degradation in the positioning performance. The proposed method addresses this by suppressing the growth in positioning error even if some beacons in the area lost or weaken their signals. Experimental results show that the average positioning error by the proposed method is 1.91m in the case that 4 of 12 beacons stop sending their signals, whereas the error by an existing method is 2.48m.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1150","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1138","bibliographicIssueDates":{"bibliographicIssueDate":"2017-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"58"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":178940,"updated":"2025-01-20T04:56:24.511155+00:00","links":{},"created":"2025-01-19T00:48:13.872517+00:00"}
