地理座標に対して規則的であり，かつ必要資源数がなるべく少ない資源割り当てを実現する．本稿では，上記のアルゴリズムを拡張したいくつかのアルゴリズムについて，760MHz 帯における路車間通信用の ITS 路側機を対象とし，それらの現実的なリソース要求および追加・除去シナリオのもとでの性能評価を行った．その結果，貪欲割当と比較し少ない資源総数および資源割当の変更数で割当を実現でき，そのようなシナリオのもとでも良好な性能を達成できることが確認できた．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告高度交通システムとスマートコミュニティ（ITS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2014-11-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"28","bibliographicVolumeNumber":"2014-ITS-59"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":107051,"updated":"2025-01-21T09:11:10.746607+00:00","links":{},"created":"2025-01-18T23:50:20.612444+00:00"}
