In this paper, we introduce a robust routing scheme, known as ad hoc on-demand multipath distance vector with dynamic path update (AOMDV-DPU), for delay-sensitive data transmission over MANET. The proposed scheme improves the AOMDV scheme by incorporating the following features: (i) a routing metric based on the combination of minimum hops and received signal strength indicator (RSSI) for discovery of reliable routes; (ii) a<jats:italic>local path update<\/jats:italic>mechanism which strengthens the route, reduces the route breakage frequency, and increases the route longevity; (iii) a<jats:italic>keep alive<\/jats:italic>mechanism for secondary route maintenance which enables smooth switching between routes and reduces the route discovery frequency; (iv) a<jats:italic>packet salvaging<\/jats:italic>scheme to improve packet delivery in the event of a route breakage; and (v) low HELLO packet overhead. The simulations are carried out in ns-2 for varying node speeds, number of sources, and traffic load conditions. Our AOMDV-DPU scheme achieves significantly higher throughput, lower delay, routing overhead, and route discovery frequency and latency compared to AOMDV. For H.264 compressed video traffic, AOMDV-DPU scheme achieves 3\u2009dB or higher PSNR gain over AOMDV at both low and high node speeds.<\/jats:p>","DOI":"10.1155\/2013\/791097","type":"journal-article","created":{"date-parts":[[2013,3,13]],"date-time":"2013-03-13T18:44:08Z","timestamp":1363200248000},"page":"1-13","source":"Crossref","is-referenced-by-count":18,"title":["Robust On-Demand Multipath Routing with Dynamic Path Upgrade for Delay-Sensitive Data over Ad Hoc Networks"],"prefix":"10.1155","volume":"2013","author":[{"given":"Sunil","family":"Kumar","sequence":"first","affiliation":[{"name":"Electrical and Computer Engineering, San Diego State University, San Diego, CA 92182, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1959-3577","authenticated-orcid":true,"given":"Siddharth","family":"Khimsara","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering, San Diego State University, San Diego, CA 92182, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kashyap","family":"Kambhatla","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering, San Diego State University, San Diego, CA 92182, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kalyani","family":"Girivanesh","sequence":"additional","affiliation":[{"name":"Electrical and Computer Engineering, San Diego State University, San Diego, CA 92182, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John D.","family":"Matyjas","sequence":"additional","affiliation":[{"name":"Air Force Research Laboratory, Rome, NY 13441, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Medley","sequence":"additional","affiliation":[{"name":"Air Force Research Laboratory, Rome, NY 13441, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"volume-title":"Dynamic source routing in ad hoc wireless networks","year":"1996","key":"6"},{"issue":"7","key":"7","doi-asserted-by":"crossref","first-page":"969","DOI":"10.1002\/wcm.432","volume":"6","year":"2006","journal-title":"Wireless Communications and Mobile Computing"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1093\/ietcom\/e88-b.9.3588"},{"issue":"3","key":"24","first-page":"166","volume":"7","year":"2010","journal-title":"International Journal of Computer Science and Information Security"},{"issue":"1","key":"25","doi-asserted-by":"crossref","first-page":"108","DOI":"10.1109\/TMC.2010.144","volume":"10","year":"2011","journal-title":"IEEE Transactions on Mobile Computing"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2003.815165"}],"container-title":["Journal of Computer Networks and Communications"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2013\/791097.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2013\/791097.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2013\/791097.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,21]],"date-time":"2017-06-21T05:17:49Z","timestamp":1498022269000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jcnc\/2013\/791097\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":6,"alternative-id":["791097","791097"],"URL":"https:\/\/doi.org\/10.1155\/2013\/791097","relation":{},"ISSN":["2090-7141","2090-715X"],"issn-type":[{"type":"print","value":"2090-7141"},{"type":"electronic","value":"2090-715X"}],"subject":[],"published":{"date-parts":[[2013]]}}}
