や Wi-Fi 等を用いた車車間遅延耐性ネットワークの構築を目指している．本システムでは，緊急車両が LoRa では転送困難な被災地の写真等の大容量データを Wi-Fi による車車間通信 (V2V) で共有する．緊急車両間の Wi-Fi 通信機会は他の被災地に移動する際のすれ違い時に限られる，Wi-Fi 通信時の転送可能データ量の最大化が課題である．しかし，Wi-Fi を用いる V2V での転送可能データ量が最大となる方法等はこれまでに明らかにされていない．本稿では，2.4GHz 帯IEEE 802.11n によるすれ違い時の V2V における TCP 送信データ量と受信信号強度 (RSSI) の変化を実環境で測定し，車が最接近する数秒間にデータが頻繁に転送され，その前後に発生する一時的なRSSI

robust even under disastrous circumstances, we have proposed a Vehicular Delay/Disruption Tolerant Network (VDTN) with multiple wireless communication media such as LPWA and Wi-Fi, each of which provides unique wireless communication characteristics to organize heterogeneity for network robustness. For the VDTN performance, it is crucial to maximize the amount of data transferred via Wi-Fi for each communication opportunity, but as far as we know, no paper has proposed a methodology that predicts the behavior of bulk data transmission in inter-vehicular communication (V2V) yet. We performed a field experiment and measured the amount of transmitted data as well as the levels of received signal strength (RSSI) over 2.4GHz IEEE 802.11n-based V2V. The experiment reveals that L2 data frames are transferred frequently in a few second-period while cars are closest, and the seconds can be predicted by detecting temporary RSSI reduction occurred around the period.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","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":"2021-05-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"22","bibliographicVolumeNumber":"2021-ITS-85"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":211336,"links":{}}
