driving system should convey visual and auditory information from a car to itsoperator on time to realize remote driving and teleoperation of a vehicle. For this objective, it is necessary to reduce the delay and to improve both availability and quality of communication for multimedia transmission. By introducing WebRTC technology which enables Peer-to-Peer transmission of multimedia and data between end devices, we can achieve the former. On the other hand, the latter is still a big challenge for vehicular communication moving inside and between coverage areas,even with the recent improvement of 3G/4G/5G cellular mobile networks. In this paper, we introduce a multipath communication technique for WebRTC to improve communicaton availability and quality. Our method utilizes multiple communication devices to reduce losses, latency and aggregate availability. We have tested our implementation with a vehicle streaming video while driving in an urban area, equipped with multiple cellular network devices. As a result, our study shows that compared to single-path transmission, WebRTC over multipath-enabledtransport achieved higher availability, reduced packet loss and latency.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌デジタルプラクティス（TDP）"}],"bibliographicPageStart":"21","bibliographicIssueDates":{"bibliographicIssueDate":"2022-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"44499"}}
