In our previous work, we assumed an environment where data items are updated and proposed two updated data dissemination methods. In these methods, the traffic for updated data dissemination is large since every mobile host necessarily requests updated data items when it knows that its own replicas are old. In this paper, we propose an updated data dissemination method exploiting an epidemic model, which is a popular bio-inspired approach, for reducing the traffic. In our method, mobile hosts disseminate invalidation reports and discard old replicas. Each mobile host that discards an old replica requests the updated data item with a certain probability. We also present simulation results to evaluate the performance of our method.","subitem_description_type":"Other"}]},"item_18_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"223","bibliographic_titles":[{"bibliographic_title":"マルチメディア通信と分散処理　ワークショップ論文集"}],"bibliographicPageStart":"219","bibliographicIssueDates":{"bibliographicIssueDate":"2005-11-30","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"19","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"item_18_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"モバイルコンピューティングII"}]},"weko_creator_id":"11"},"created":"2025-01-18T23:39:25.218255+00:00","updated":"2025-01-21T16:24:21.134996+00:00"}
