Mobile Convergence, FMC）環境下でのP2Pの利用を想定し，モバイル端末の存在を考慮したDHT（Distributed Hash Table）アルゴリズムの拡張手法の提案を行う．モバイル端末のバッテリ消費を抑えるため，FMC環境における計算資源である固定端末へモバイル端末の通信処理を委譲する非対称型DHTアルゴリズムを提案する．これにより，モバイル端末においてバッテリ消費量の大きな通信処理負荷を抑制することができ，かつ従来の探索性能を維持したDHTを構築することが可能となる．提案手法について，シミュレーションによる性能評価を行った結果，従来手法より探索遅延時間を改善できていることが分かった．","subitem_description_type":"Abstract"}]},"item_5_select_10":{"attribute_name":"単著共著","attribute_value_mlt":[{"subitem_select_item":"共著/joint"}]},"item_5_select_8":{"attribute_name":"査読有無","attribute_value_mlt":[{"subitem_select_item":"あり/yes"}]},"item_5_select_9":{"attribute_name":"研究業績種別","attribute_value_mlt":[{"subitem_select_item":"原著論文/Original
