In coventional protocols for wired networks, stable storages to store state information are assumed and enough bandwidth is assigned to synchronize a sender and a receiver computers of a message in order to avoid that the message becomes inconsistent, i.e.  neither orphan nor lost. In this paper, we propose a novel checkpoint protocol in ad hoc networks without stable storage and enough communication bandwidth. Here, a checkpoint request message is delivered by flooding. State information of a mobile computer is carried by this message and stored into neighbor mobile computers. A candidate of a lost message is detected and stored by intermediate mobile computer on its transmission route. Here, communication overhead for taking global checkpoint is reduced.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"296","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告コンピュータセキュリティ（CSEC）"}],"bibliographicPageStart":"291","bibliographicIssueDates":{"bibliographicIssueDate":"2007-03-02","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"16(2007-CSEC-036)","bibliographicVolumeNumber":"2007"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T23:10:40.840737+00:00","id":44524,"links":{}}
