In the early works, it has been shown that it is sometimes possible to use routing protocols for Mobile Ad hoc Networks (MANET) to provide an end-to-end data delivery services in such environments. However, if the networks seriously suffer from the low network connectivity, the routing protocols for MANET cannot provide the communication service along the end-to-end path because keeping the end-to-end path is difficult in such disrupted networks. Even in such cases, the routing protocols for DTN can support the communication services using the opportunistic contacts of mobile nodes to extend the network connectivity in the mobile wireless networks with low connectivity. In this dissertation, we have focused on the review of several routing protocols for DTN as related works to motivate the problems of early studies and we proposed a novel routing protocol to use mean residual contact time which can reduce the delivery latency of the routing protocols in mobile DTN. The simulation results support that the proposed method can improve the performance of routing protocols for DTN. In addition, we introduce a new metric which can show in what situations the proposed method provides more efficient data delivery service. Variation Metric can be used to characterize these situations in the degree of different contact interval among mobile nodes.","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"新潟大学大学院自然科学研究科","subitem_description_type":"Other"},{"subitem_description":"平成24年3月23日","subitem_description_type":"Other"},{"subitem_description":"新大院博（工）甲第385号","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博（工）甲第385号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第3671号"}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"50056","nameIdentifierScheme":"WEKO"}],"names":[{"name":"金, 容杓"}]}]},"item_6_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学"}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kim, Yong-Pyo"}],"nameIdentifiers":[{"nameIdentifier":"50055","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-05"}],"displaytype":"detail","filename":"D_S_K_K385.pdf","filesize":[{"value":"5.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/5298/files/D_S_K_K385.pdf"},"version_id":"d4be00f0-e31a-4367-8ab3-9d4ccbd4eea1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Research of Routing Protocols in Mobile Delay Tolerant Networks","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Research of Routing Protocols in Mobile Delay Tolerant Networks"},{"subitem_title":"Research of Routing Protocols in Mobile Delay Tolerant Networks","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["455","564"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-01-22"},"publish_date":"2013-01-22","publish_status":"0","recid":"5298","relation_version_is_last":true,"title":["Research of Routing Protocols in Mobile Delay Tolerant Networks"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T03:38:17.580946+00:00"}
