IEEE 802.16 mesh networks are likely to be the basis of next-generation last mile network connectivity. So, providing QoS is one of the major designing goals in IEEE 802.16 mesh network. While the standard defines five service classes for PMP mode, no standard defined service classes exist for mesh mode. In this paper, we describe a differentiated service (DiffServ) architecture for QoS support in IEEE 802.16 mesh network by considering a basic requirement for QoS guarantee\u2014delay. A new cross-layer routing metric is proposed, namely, expected scheduler delay (ESD). An efficient distributed scheme is proposed to calculate ESD and route the packets using source routing mechanism. This scheme is capable of differentiating between delay sensitive and best-effort traffic and route packets accordingly. Finally, the results of the proposed scheme are compared with the standard schemes that take hop count as a routing metric.<\/jats:p>","DOI":"10.1155\/2011\/951310","type":"journal-article","created":{"date-parts":[[2011,11,3]],"date-time":"2011-11-03T19:03:58Z","timestamp":1320347038000},"page":"1-13","source":"Crossref","is-referenced-by-count":3,"title":["A DiffServ Architecture for QoS-Aware Routing for Delay-Sensitive and Best-Effort Services in IEEE 802.16 Mesh Networks"],"prefix":"10.1155","volume":"2011","author":[{"given":"Ishita","family":"Bhakta","sequence":"first","affiliation":[{"name":"School of Mobile Computing and Communications, Jadavpur University, Kolkata 700032, India"}]},{"given":"Sandip","family":"Chakraborty","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Indian Institute of Technology Guwahati, Guwahati 781039, India"}]},{"given":"Barsha","family":"Mitra","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Jadavpur University, Kolkata 700032, India"}]},{"given":"Debarshi Kumar","family":"Sanyal","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Jadavpur University, Kolkata 700032, India"}]},{"given":"Samiran","family":"Chattopadhyay","sequence":"additional","affiliation":[{"name":"Department of Information Technology, Jadavpur University, Kolkata 700032, India"}]},{"given":"Matangini","family":"Chattopadhyay","sequence":"additional","affiliation":[{"name":"School of Education Technology, Jadavpur University, Kolkata 700032, India"}]}],"member":"98","reference":[{"key":"12","doi-asserted-by":"publisher","DOI":"10.1002\/dac.581"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2008.2005221"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2009.091427"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/65.768484"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2006.1668391"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/MNET.2008.4435897"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2007.912330"}],"container-title":["Journal of Computer Networks and Communications"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2011\/951310.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2011\/951310.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jcnc\/2011\/951310.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,10,11]],"date-time":"2016-10-11T21:35:23Z","timestamp":1476221723000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/jcnc\/2011\/951310\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":7,"alternative-id":["951310","951310"],"URL":"https:\/\/doi.org\/10.1155\/2011\/951310","relation":{},"ISSN":["2090-7141","2090-715X"],"issn-type":[{"value":"2090-7141","type":"print"},{"value":"2090-715X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
