However, VoIP applications make a very inefficient use of the MANET resources. Our work represents a first step toward improving aspects at the network layer by addressing issues from the standpoint of adaptation, claiming that effective adaptation of routing parameters can enhance VoIP quality. The most important contribution is the adaptive OLSR-VA algorithm which provides an integrated environment where VoIP activity is constantly detected and routing parameters are adapted in order to meet the application requirements. To investigate the performance advantage achieved by such algorithm, a number of realistic simulations (MANET scenarios) are performed under different conditions. The most important observation is that performance is satisfactory in terms of the perceived voice quality.<\/jats:p>","DOI":"10.1155\/2014\/945695","type":"journal-article","created":{"date-parts":[[2014,10,7]],"date-time":"2014-10-07T17:05:08Z","timestamp":1412701508000},"page":"1-10","source":"Crossref","is-referenced-by-count":2,"title":["A New QoS Management Scheme for VoIP Application over Wireless Ad Hoc Networks"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6757-3506","authenticated-orcid":true,"given":"Said","family":"El brak","sequence":"first","affiliation":[{"name":"Department of Computer Science, Abdelmalek Essaadi University, 90100 Tangier, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohamed","family":"El brak","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Abdelmalek Essaadi University, 90100 Tangier, Morocco"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Driss","family":"Benhaddou","sequence":"additional","affiliation":[{"name":"Department of Engineering Technology, Houston University, Houston, TX 77004, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-006-9164-0"},{"key":"3","series-title":"Lecture Notes in Computer Science","doi-asserted-by":"crossref","first-page":"168","DOI":"10.1007\/978-3-642-12104-3_14","volume-title":"Setting the parameters right for two-hop IEEE 802.11e ad hoc networks","volume":"5987","year":"2010"},{"key":"4","first-page":"52","volume-title":"VoIP Codec adaptation algorithm in multirate 802.11 WLANs: distributed vs. centralized performance comparison","volume":"4606","year":"2007"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2011.11.002"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-005-8724-z"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2014.2307315"},{"issue":"1","key":"11","first-page":"68","volume":"50","year":"2013","journal-title":"Journal of Theoretical and Applied Information Technology"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-008-0158-6"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2011.120811.00063"},{"year":"2008","key":"17"}],"container-title":["Journal of Computer Networks and Communications"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2014\/945695.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2014\/945695.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2014\/945695.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T17:59:07Z","timestamp":1498154347000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jcnc\/2014\/945695\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":10,"alternative-id":["945695","945695"],"URL":"https:\/\/doi.org\/10.1155\/2014\/945695","relation":{},"ISSN":["2090-7141","2090-715X"],"issn-type":[{"type":"print","value":"2090-7141"},{"type":"electronic","value":"2090-715X"}],"subject":[],"published":{"date-parts":[[2014]]}}}
