In this paper, we focus on a time of arrival (TOA)-based localization technique, as it has better location estimation performance than other radio frequency-based techniques. However, the propagation speed of signals transmitted from inside of a human body varies depending on which biological tissues they pass through. For this reason, almost all of conventional TOA-based methods have to obtain the relative permittivity of the passed biological tissues or the propagation speed beforehand through another measurement system, i.e., magnetic resonance imaging (MRI) or computational tomography (CT). To avoid such troublesome pre-measurement, we propose a hybrid TOA/received signal strength indicator (RSSI)-based method, which can simultaneously estimate the WCE location and the averaged relative permittivity of the human body. First, we derive the principle of RSSI-based relative permittivity estimation from an finite difference time domain (FDTD) simulation. Second, we combine the TOA-based localization and the proposed RSSI-based relative permittivity estimation, and add them to the particle filter tracking technique. Finally, we perform computer simulations to evaluate the estimation accuracy of the proposed method. The simulation results show that the proposed method can accomplish good localization performance, 1.3mm, without pre-measurement of the human body structure information.","subitem_description_type":"Other"}]},"item_10001_description_38":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{},{}],"names":[{"name":"安在, 大祐"}]},{"nameIdentifiers":[{},{}],"names":[{"name":"王, 建青"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Institute of Electronics, Information and Communication Engineers "}]},"item_10001_relation_34":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1587/transcom.2015EBP3439"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1587/transcom.2015EBP3439","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_35":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"130005268111"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ci.nii.ac.jp/naid/130005268111","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_37":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.ieice.org/jpn/books/transaction.html"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.ieice.org/jpn/books/transaction.html","subitem_relation_type_select":"URI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09168516","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"書誌レコードID（NCID）","attribute_value_mlt":[{"subitem_source_identifier":"AA11510208","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ito, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Anzai, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Wang, Jianqing","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-12"}],"displaytype":"detail","filename":"AnzaiDaisuke_2016_P1.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","license_note":"copyright(C)2016 IEICE","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/6370/files/AnzaiDaisuke_2016_P1.pdf"},"version_id":"80c47ae5-6f24-4b79-b8fc-03249a3cd465"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"WCE","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"localization","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"BAN","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"TOA","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"RSSI","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"particle filter","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Hybrid TOA/RSSI-Based Wireless Capsule Endoscope Localization with Relative Permittivity Estimation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Hybrid TOA/RSSI-Based Wireless Capsule Endoscope Localization with Relative Permittivity Estimation","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"3","path":["31"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-12"},"publish_date":"2018-11-12","publish_status":"0","recid":"6370","relation_version_is_last":true,"title":["Hybrid TOA/RSSI-Based Wireless Capsule Endoscope Localization with Relative Permittivity Estimation"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T13:34:41.030587+00:00"}
