Due to the high dynamic nature of VANETs, choosing a relatively stable and reliable transmission path to reduce the link breakage is obviously very important. In this paper, we propose an efficient prediction-based data forwarding strategy to ensure the reliability and efficiency of data transmission in VANETs. Besides the link lifetime prediction, we introduce a new metric named link utility used in the process of forwarder selection, in order to improve data forwarding efficiency. Link utility reflects the impact of relative velocity and distance between the vehicles on the efficiency of intervehicle data transmissions. It can be used to optimize packet routing and minimize number of hops especially in the high-density VANETs. Finally, we evaluate the performance of the proposed forwarding strategy through simulation confirming its feasibility and effectiveness. <\/jats:p>","DOI":"10.1155\/2015\/128725","type":"journal-article","created":{"date-parts":[[2015,8,27]],"date-time":"2015-08-27T21:30:11Z","timestamp":1440711011000},"page":"128725","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["An Efficient Prediction-Based Data Forwarding Strategy in Vehicular Ad Hoc Network"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7076-9881","authenticated-orcid":false,"given":"Wanting","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Deyun","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Electronic and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}]},{"given":"Chuan Heng","family":"Foh","sequence":"additional","affiliation":[{"name":"Centre for Communication Systems Research, Department of Electronic Engineering, University of Surrey, Surrey GU2 7XH, UK"}]}],"member":"179","published-online":{"date-parts":[[2015,8,27]]},"reference":[{"key":"B1-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/surv.2011.061411.00019"},{"issue":"3","key":"B2-2015-128725","first-page":"913","volume":"26","author":"Lin Y.-W.","year":"2010","journal-title":"Journal of Information Science & Engineering"},{"key":"B3-2015-128725","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2013.09.008"},{"key":"B4-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/trustcom.2012.53"},{"key":"B5-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2007.897656"},{"key":"B6-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/icnsc.2013.6548703"},{"key":"B7-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/cit.2010.448"},{"key":"B8-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/icc.2013.6654769"},{"key":"B9-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/glocom.2012.6503111"},{"key":"B10-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/wcnc.2013.6554814"},{"key":"B11-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2013.022213.122554"},{"key":"B12-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/TITS.2011.2156406"},{"key":"B13-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/icacci.2013.6637387"},{"key":"B14-2015-128725","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2012.03.007"},{"key":"B15-2015-128725","doi-asserted-by":"publisher","DOI":"10.1109\/vetecs.2008.94"},{"key":"B16-2015-128725","doi-asserted-by":"publisher","DOI":"10.1145\/192161.192233"},{"key":"B18-2015-128725","doi-asserted-by":"publisher","DOI":"10.4108\/icst.simutools2009.5674"},{"first-page":"825","volume-title":"Proceedings of the 22nd Annual Joint Conference on the IEEE Computer and Communications Societies (INFOCOM \u203203)","author":"Bai F.","key":"B19-2015-128725"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/128725","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2015\/128725","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/128725","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,5]],"date-time":"2021-05-05T11:33:55Z","timestamp":1620214435000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1155\/2015\/128725"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,8,1]]},"references-count":18,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2015,8,1]]}},"alternative-id":["10.1155\/2015\/128725"],"URL":"https:\/\/doi.org\/10.1155\/2015\/128725","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"type":"print","value":"1550-1477"},{"type":"electronic","value":"1550-1477"}],"subject":[],"published":{"date-parts":[[2015,8,1]]}}}
