WebRTC を用いる環境を想定し，通信品質向上への MP-QUIC プロトコルの適用可能性検証を行う．WebRTC は，インターネットにおいて端末・サーバ間で P2P 通信路を確立し通信を行うため，遠隔運転に必要な低遅延な通信を実現できる可能性がある．しかし，移動する自動車からの通信は不安定になることもあり，遠隔運転の安全性を高めるためにより安定した通信方式を確立しなければならない．そこで，本研究では複数の異なる通信回線を利用して通信を行うマルチパス通信プロトコルの一つである MP-QUIC を採用することにより，WebRTC 通信の可用性および品質の向上を試みる．MP-QUIC は，ユーザランドで動作し低遅延なトランスポートプロトコルである QUIC を対象にマルチパス通信技術を導入しており，遠隔運転に必要な通信品質を安定的に提供できる可能性がある．評価では，WebRTC を用いた映像伝送システムに対して MP-QUIC の組み込み，市街地を走行する自動車から複数の移動体通信回線を用いた映像メディアの伝送を実施し，遅延および映像品質の計測を行う．","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-02-28","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2022-IOT-56"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:17:16.486146+00:00","id":216759,"links":{}}
