Therefore, situations that mobile nodes cannot access the data on other terminals will occur. As the solution method of such a problem, replica distribution methods which distribute the replicas of data items to other terminals and maintain them have been proposed, and we have proposed SC (Skip Copy) method as one of them.This method distributes location dependent data items requested by geocast around the source location of them, and achives high accessibility to data while it does not require many redundant replicas. However cache invalidation  method have not been fully taken into consideration in our past evaluation. In this paper, we study on cache invalidation method and evaluate the SC method by simulation including some cache invalidation methods.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告モバイルコンピューティングとユビキタス通信（MBL）"}],"bibliographicPageStart":"17","bibliographicIssueDates":{"bibliographicIssueDate":"2005-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"90(2005-MBL-034)","bibliographicVolumeNumber":"2005"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":43655,"links":{}}
