(Device-to-Device, D2D) 機能を介して，近隣端末群のストレージをまとめて一つのキャッシュとして扱う仕組みが効果的である．しかし，端末を跨いだコンテンツ配置計算は負荷が高く，また端末の位置は頻繁に変化するため，計算が追従できず効果がスケールしない．本研究報告では，モバイル環境におけるコンテンツ配信の効率化を目的に，2D

amount of Video-On-Demand (VOD) service traffic is explosively growing under the mobile internet environment. To reduce traffic, Device-to-Device communication, which enables direct communication between devices in a long range and high throughput is exploited. Moreover, several distributed cache mechanisms have been proposed to follow growing traffic by offloading to D2D communications. These techniques group neighbor devices to construct a distributed large cache by collaborative technique. However, these techniques require additional information and heavy calculation to determine the arrangement of contents. This report proposes a lightweight method to determine contents arrangement in the crowded devices. Unique ID called tag distinguishes each device and a control signal is sent from a base station to follow the situation changes. Mathematical simulations show that the tag mechanism achieves high traffic offloading rate in both more and less device situations.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-03-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"65","bibliographicVolumeNumber":"2017-SLDM-179"}]},"relation_version_is_last":true,"weko_creator_id":"11"}}
