To reduce fragmentation, the spectrum is partitioned based on the clique partitioning approach and spectral slots are assigned to traffic demands depending on which partition they belong. Simulation results predict that the proposed approach has better spectrum slot utilization compared to the state\u2010of\u2010the\u2010art non\u2010partitioning approach and the proposed approach reduces fragmentation, and also has less blocking ratio compared to the state\u2010of\u2010the\u2010art partitioning approach.<\/jats:p>","DOI":"10.1002\/dac.4333","type":"journal-article","created":{"date-parts":[[2020,2,3]],"date-time":"2020-02-03T21:17:03Z","timestamp":1580764623000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Traffic grooming and clique partitioning\u2010based spectrum assignment in elastic optical networks"],"prefix":"10.1002","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5143-7275","authenticated-orcid":false,"given":"Panchali","family":"Datta Choudhury","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering National Institute Of Technology  Durgapur India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neha","family":"Agarwal","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering National Institute Of Technology  Durgapur India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanmay","family":"De","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering National Institute Of Technology  Durgapur India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,2,3]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"Trends & More Internet Live Stats.http:\/\/www.internetlivestats.com\/internet-users\/. accessed october 17;2019."},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2012.6146481"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2009.5307468"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/JLT.2011.2159482"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/JLT.2008.2010061"},{"key":"e_1_2_8_7_1","doi-asserted-by":"crossref","unstructured":"ChristodoulopoulosK TomkosI VarvarigosEA.Routing and spectrum allocation in OFDM\u2010based optical networks with elastic bandwidth allocation.
