However, because datalinks could be physically disrupted in DTN environment, global synchronization in the network is absolutely difficult, which indicates the traditional routing schemes cannot work appropriately. We propose Topology Change Tolerant Routing (TCTR), which does not need global synchronization in the network for message delivery. In fact, TCTR is an instance of Potential-Based Routing (PBR) which selects the next hop of messages only using the relative information with its neighbor nodes. We have developed a prototype system and TCTR simulator. TCTR has achieved message delivery over highlydynamic topology scenarios, which MANET protocols cannot be applied to. We evaluated the performance of TCTR regarding to message delivery time, transmission cost and message pool size in comparison with Epidemic Routing, which provides tolerance for topology changes by flooding mechanism.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2326","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2312","bibliographicIssueDates":{"bibliographicIssueDate":"2009-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"50"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":66481,"updated":"2025-01-22T01:02:40.743328+00:00","links":{},"created":"2025-01-18T23:27:13.931320+00:00"}
