Therefore, quickand reliable detection of the deterioration of a wireless link condition isessential for avoiding the degradation of the communication quality duringhandover. In our previous works, we focused on a handover decisioncriterion allowing MNs to maintain communication quality and statedthe problems of existing decision criteria. Furthermore, we showed theeffectiveness of the number of frame retransmissions through simulationexperiments. However, a comparison between signal strength and thenumber of frame retransmissions could not be examined due to the unreliabilityof signal strength in simulations. Therefore, in this paper, byemploying FTP and VoIP applications, we compare signal strength andthe number of frame retransmissions as a handover decision criterionwith experiments in terms of (1) and (2) in a real environment. Finally,we show the problems of signal strength in contrast to the effectivenessof the number of frame retransmissions as a handover decision criterion.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"affiliations":[{"affiliationNames":[{"lang":"ja"}]}]},{"affiliations":[{"affiliationNames":[{"lang":"ja"}]}]}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"Springer"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1007/11890348_19","subitem_relation_type_select":"DOI"}}]},"item_21_relation_9":{"attribute_name":"ISBN","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"978-3-540-46287-3","subitem_relation_type_select":"ISBN"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"Copyright (c) Springer-Verlag Berlin Heidelberg 2006"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1611-3349","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"0302-9743","subitem_source_identifier_type":"PISSN"}]},"item_21_version_type_58":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"Tsukamoto, Kazuya","creatorNameLang":"en"},{"creatorName":"塚本, 和也","creatorNameLang":"ja"},{"creatorName":"ツカモト, カズヤ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kashihara, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"Oie, Yuji","creatorNameLang":"en"},{"creatorName":"尾家, 祐二","creatorNameLang":"ja"},{"creatorName":"オイエ, ユウジ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2007-11-27"}],"displaytype":"detail","filename":"KazuyaTsukamoto-20061012-UCS.pdf","filesize":[{"value":"414.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KazuyaTsukamoto-20061012-UCS.pdf","url":"https://kyutech.repo.nii.ac.jp/record/189/files/KazuyaTsukamoto-20061012-UCS.pdf"},"version_id":"2b845778-c53e-4cb6-bce5-198cbd7b84e8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Wireless LAN Handover","subitem_subject_scheme":"Other"},{"subitem_subject":"Handover Decision Criterion","subitem_subject_scheme":"Other"},{"subitem_subject":"Signal Strength","subitem_subject_scheme":"Other"},{"subitem_subject":"Frame retransmission","subitem_subject_scheme":"Other"},{"subitem_subject":"FTP","subitem_subject_scheme":"Other"},{"subitem_subject":"VoIP","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":"Experimental Evaluation of Decision Criteria for WLAN handover:Signal Strength and Frame Retransmission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experimental Evaluation of Decision Criteria for WLAN handover:Signal Strength and Frame Retransmission","subitem_title_language":"en"}]},"item_type_id":"21","owner":"3","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-27"},"publish_date":"2007-11-27","publish_status":"0","recid":"189","relation_version_is_last":true,"title":["Experimental Evaluation of Decision Criteria for WLAN handover:Signal Strength and Frame Retransmission"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-12-05T06:12:36.607255+00:00"}
