の台頭と動画コンテンツの高画質化に伴って通信量が大きく増大している．多くの端末からアクセスを受ける基地局への負荷を減らすために，基地局を介さずに隣接端末をキャッシュサーバとして利用する，Device-to-Device(D2D) 通信による分散協調キャッシュ手法が提案されている．また，コンテンツをチャンク分割したうえでキャッシュする手法や画質レイヤごとにデータを細分化した手法も提案されている．我々の提案する色キャッシュでは単一ホップの D2D 通信について検討してきたが，マルチホップ D2D 通信の活用を考慮していなかった．本研究では，既存のモバイル環境におけるキャッシュ制御手法に対して，マルチホップ D2D 通信を利用することによる効果について報告する．D2D

Internet traffics have been increasing significantly with the rise of VOD and the increase in the quality of video content. In order to reduce the load on base stations that receive request from many mobile users, a distributed cooperative caching techniques based on device-to-device(D2D) communication have been proposed, in which a neighboring mobile is used as a cache server without going through a base station. In addition, a method to cache contents in chunks and a method to subdivide data by image quality layer have also been proposed. On the other hand, our previous works only consider single-hop D2D communication and do not utilize multi-hop D2D communication. In this research, we report the effect of using multi-hop D2D communication with our proposed cache control method in the mobile environment. By adding diversity to the cache contents in the communication range of D2D communication, we can reduce the load on base stations.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告組込みシステム（EMB）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-03-16","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2023-EMB-62"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":225512,"links":{}}
