型データ配信を用いる次世代気象データ交換システムである WMO Information System 2.0 (WIS2.0) において，subscriber が受信するメッセージに対する時間制約をなるべく満足するような Broker からのメッセージ配信手法を提案する．WIS2.0 のように大量のノードが接続され，多地点で発生する様々なデータに対するサービス・アプリケーション要求が混在する環境では，Broker が subscriber にメッセージを送信する適切なタイミングは，publisher の配信タイミング，subscriber の処理時間，ネットワーク帯域，メッセージタイプやデータ量など複数の要因に依存する．したがって，それらすべての要因を考慮した配信手法の手動設計は容易でない．これに対し提案手法では，機械学習モデルを使用して Broker が送信すべきメッセージの到着予測と応答遅延予測を行い，その予測値を活用して最適な配信タイミングを学習する強化学習モデルによる動的スケジューリングアルゴリズムを提案する．送信メッセージに対する応答遅延には subscriber でのアプリケーション処理が含まれ，予測のためにはメッセージ のsemantics が重要である．提案手法では subscriber でのメッセージの処理遅延を予測するためにメッセージの topic を入力として自然言語処理モデルである BERT を使用した．ネットワークシミュレータを用いた実験において最新手法と比較して提案手法はメッセージの期限内配信の成功率を 28% 向上させられることを示した．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告マルチメディア通信と分散処理（DPS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-12-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"2023-DPS-197"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T10:44:13.504626+00:00","created":"2025-01-19T01:31:51.314600+00:00","links":{}}
