The existing routing algorithms of DTNs do not meet the current city environments due to the large differences in node densities, social characteristics, and limited energy. The key indicators of DTNs such as success delivery ratio, average delivery latency, network lifetime, and network overhead ratio can influence the performances of civil DTNs applications. Aiming to improve the key indicators of DTNs in city environments, this paper presents a fixed sink station based structure and a more proper routing algorithm named Game Theory Based Decision Making (GTDM). GTDM shows decision-making process for neighborhood selection and packet delivering strategy which is based on the noncooperative game theory method and city environment characteristics. GTDM performance is evaluated using numerical simulations under Working Day Movement (WDM) model and the results suggested that GTDM outperforms other traditional DTNs routing approaches, such as Epidemic and Prophet algorithms.<\/jats:p>","DOI":"10.1155\/2015\/410298","type":"journal-article","created":{"date-parts":[[2015,6,2]],"date-time":"2015-06-02T10:05:37Z","timestamp":1433239537000},"page":"1-9","source":"Crossref","is-referenced-by-count":1,"title":["GTDM: A DTN Routing on Noncooperative Game Theory in a City Environment"],"prefix":"10.1155","volume":"2015","author":[{"given":"Wenzao","family":"Li","sequence":"first","affiliation":[{"name":"College of Electronics and Information Engineering, Sichuan University, Chengdu 610065, China"},{"name":"College of Communication Engineering, Chengdu University of Information Technology, Chengdu 610225, China"}]},{"given":"Feng","family":"Lin","sequence":"additional","affiliation":[{"name":"School of Computer Science, Sichuan University, Chengdu 610065, China"}]},{"given":"Jiliu","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Computer Science, Sichuan University, Chengdu 610065, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4597-2060","authenticated-orcid":true,"given":"Yan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Sichuan University, Chengdu 610065, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1147\/jrd.2010.2092257"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-012-0912-z"},{"issue":"3","key":"9","doi-asserted-by":"crossref","first-page":"152","DOI":"10.5121\/ijcnc.2010.2312","volume":"2","year":"2010","journal-title":"International Journal of Computer Networks"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3390\/s120709055"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaceta.2008.07.003"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-12808-0_19"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2012.6231292"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-77105-0_31"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-015-2330-5"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2012.03.018"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/410298.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/410298.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2015\/410298.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,23]],"date-time":"2017-06-23T08:48:53Z","timestamp":1498207733000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/js\/2015\/410298\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":10,"alternative-id":["410298","410298"],"URL":"https:\/\/doi.org\/10.1155\/2015\/410298","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2015]]}}}
