Most routing algorithms employ a paradigm by which a node can keep the receiving messages, carrying the messages with them when moving and then forwarding the messages to the opportunistic meeting nodes when possible. This routing model works well in the networks with high-to-moderate node density in which the opportunity that the moving nodes can meet with each other is rather high. On the other hand, the delivery ratio becomes remarkably low in the sparse network environment especially when there is a strict constraint on message delivery deadline. In this paper, we introduce the novel concept of rendezvous place where the passing nodes can announce, deposit, or pick up their own messages without having to meet the other nodes carrying the desired message. The rendezvous place can be detected automatically and its area's shape is dynamically changed according to the interaction among nodes. The results from extensive simulations show that our routing algorithm can achieve higher delivery ratio and utilize lower energy consumption than traditional opportunistic routing algorithms especially in sparse network environment. <\/jats:p>","DOI":"10.1155\/2015\/819178","type":"journal-article","created":{"date-parts":[[2015,2,26]],"date-time":"2015-02-26T21:04:03Z","timestamp":1424984643000},"page":"819178","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Dynamic Rendezvous Based Routing Algorithm on Sparse Opportunistic Network Environment"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0257-131X","authenticated-orcid":false,"given":"Jiradett","family":"Kerdsri","sequence":"first","affiliation":[{"name":"School of Information, Computer, and Communication Technology (ICT), Sirindhorn International Institute of Technology, Nonthaburi 11120, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Komwut","family":"Wipusitwarakun","sequence":"additional","affiliation":[{"name":"School of Information, Computer, and Communication Technology (ICT), Sirindhorn International Institute of Technology, Nonthaburi 11120, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,2,26]]},"reference":[{"key":"B1-2015-819178","first-page":"27","volume-title":"Taxonomy of Opportunistic Routing: Principles and Behaviors","author":"Zeng K.","year":"2011"},{"key":"B2-2015-819178","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2011.05.005"},{"key":"B3-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/tpds.2011.182"},{"key":"B4-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/milcom.2005.1606153"},{"issue":"13","key":"B5-2015-819178","first-page":"91","volume":"8","author":"Kerdsri J.","year":"2013","journal-title":"Journal of Convergence Information Technology"},{"first-page":"227","volume-title":"Proceedings of the 2nd International Conference on Embedded Networked Sensor Systems (SenSys '04)","author":"Zhang P.","key":"B6-2015-819178"},{"first-page":"233","volume-title":"Proceedings of the 4th ACM International Symposium on Mobile Ad Hoc Networking and Computing (MOBIHOC '03)","author":"Small T.","key":"B7-2015-819178"},{"key":"B8-2015-819178","doi-asserted-by":"publisher","DOI":"10.1002\/9781118511305.ch9"},{"key":"B9-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2009.5350376"},{"key":"B10-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/apcc.2011.6152850"},{"key":"B11-2015-819178","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-010-0276-9"},{"key":"B12-2015-819178","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-37015-1_75"},{"key":"B13-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/waina.2008.292"},{"first-page":"235","volume-title":"Proceedings of the 1st Annual IEEE Communications Society Conference on Sensor and Ad Hoc Communications and Networks (SECON '04)","author":"Spyropoulos T.","key":"B14-2015-819178"},{"key":"B15-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2002.801403"},{"key":"B17-2015-819178","doi-asserted-by":"publisher","DOI":"10.1109\/mwc.2013.6590061"},{"key":"B18-2015-819178","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2010.05.012"},{"first-page":"1180","volume-title":"Proceedings of the 4th International IFIP-TC6 Networking Conference: Networking Technologies, Services, and Protocols; Performance of Computer and Communication Networks; Mobile and Wireless Communications Systems (NETWORKING '05)","author":"Harras K.
