Thus, many applications which require reliable broadcast cannot work properly if they lost some packets. In order to make sure every sensor node in the network receives all packets completely and correctly, retransmission of lost packets is indispensable. Many retransmission methods with network coding have been proposed but they do not catch coding opportunity. In this paper, real-time retransmission algorithm based on network coding (NCRR) is proposed to make the average number of transmissions as less as possible. During the transmission of original packets, we detect whether a certain time slot is suitable for retransmitting a coded packet based on recovery ratio. We analyze the number of transmissions with traditional retransmission and with network coding. Compared with existing approaches, simulation results show that our algorithm can effectively reduce the average number of transmissions and improve the transmission efficiency. <\/jats:p>","DOI":"10.1155\/2015\/536247","type":"journal-article","created":{"date-parts":[[2015,6,14]],"date-time":"2015-06-14T21:01:28Z","timestamp":1434315688000},"page":"536247","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Network Coding-Based Real-Time Retransmission Scheme in Wireless Sensor Networks"],"prefix":"10.1177","volume":"11","author":[{"given":"Chang","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, Suzhou 215006, China"}]},{"given":"Yanqin","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, Suzhou 215006, China"}]},{"given":"Lingzhi","family":"Li","sequence":"additional","affiliation":[{"name":"School of Computer Science & Technology, Soochow University, Suzhou 215006, China"}]}],"member":"179","published-online":{"date-parts":[[2015,6,14]]},"reference":[{"key":"B1-2015-536247","doi-asserted-by":"publisher","DOI":"10.1145\/990064.990096"},{"first-page":"214","volume-title":"Proceedings of the 2nd International Conference on Embedded Networked Sensor Systems (SenSys \u203204)","author":"Szewczyk R.","key":"B2-2015-536247"},{"first-page":"13","volume-title":"Proceedings of the 2nd International Conference on Embedded Networked Sensor Systems (SenSys \u203204)","author":"Xu N.","key":"B3-2015-536247"},{"key":"B4-2015-536247","doi-asserted-by":"publisher","DOI":"10.1145\/1134680.1134693"},{"key":"B5-2015-536247","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-77690-1_17"},{"key":"B6-2015-536247","doi-asserted-by":"publisher","DOI":"10.1109\/18.850663"},{"key":"B7-2015-536247","doi-asserted-by":"publisher","DOI":"10.1145\/1151659.1159942"},{"key":"B8-2015-536247","doi-asserted-by":"publisher","DOI":"10.1109\/wc-m.2006.250362"},{"key":"B9-2015-536247","doi-asserted-by":"publisher","DOI":"10.1109\/GLOCOMW.2011.6162478"},{"volume-title":"Proceedings of the 27th Conference on Computer Communications (INFOCOM \u203208)","author":"Hou I.-H.","key":"B10-2015-536247"},{"key":"B11-2015-536247","doi-asserted-by":"publisher","DOI":"10.1109\/apcc.2009.5375692"},{"issue":"1","key":"B12-2015-536247","first-page":"64","volume":"33","author":"Lu J.","year":"2012","journal-title":"Journal on Communications"},{"issue":"5","key":"B13-2015-536247","first-page":"1214","volume":"39","author":"Lu J.","year":"2011","journal-title":"Acta Electronica Sinica"},{"key":"B14-2015-536247","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2008.927729"},{"key":"B15-2015-536247","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/852472"},{"first-page":"709","volume-title":"Proceedings of the International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC \u203297)","author":"Naijoh M.","key":"B16-2015-536247"},{"key":"B17-2015-536247","doi-asserted-by":"publisher","DOI":"10.1145\/285243.285289"},{"key":"B18-2015-536247","doi-asserted-by":"publisher","DOI":"10.1155\/2010\/465915"},{"issue":"8","key":"B19-2015-536247","first-page":"35","volume":"32","author":"Long S.","year":"2013","journal-title":"Transducer and Microsystem Technologies"},{"key":"B20-2015-536247","doi-asserted-by":"publisher","DOI":"10.3724\/sp.j.1146.2011.01233"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/536247","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2015\/536247","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2015\/536247","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,6]],"date-time":"2021-05-06T01:25:48Z","timestamp":1620264348000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1155\/2015\/536247"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,6,1]]},"references-count":20,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2015,6,1]]}},"alternative-id":["10.1155\/2015\/536247"],"URL":"https:\/\/doi.org\/10.1155\/2015\/536247","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"type":"print","value":"1550-1477"},{"type":"electronic","value":"1550-1477"}],"subject":[],"published":{"date-parts":[[2015,6,1]]}}}
