This article deals with some of the important characteristics of the spectrum mobility in cognitive radio networks (CRNs).The new management approach to the mobility and the connection are designed to reduce the latency and loss of information during spectrum handoff. A list of channel safeguards are maintained in this effect, but the maintenance and updates are a challenge. In this article, the authors describe the reasons and mechanisms for spectrum handoff. Algorithms have been developed to illustrate this handoff mechanism and make the comparison between the different methods of spectrum handoff. The simulation results obtained confirm that the proposed method and the algorithms developed presents a better performance.<\/jats:p>","DOI":"10.4018\/ijtd.2019100102","type":"journal-article","created":{"date-parts":[[2019,8,27]],"date-time":"2019-08-27T10:55:03Z","timestamp":1566903303000},"page":"19-35","source":"Crossref","is-referenced-by-count":4,"title":["Spectrum Handoff Mechanism in the Framework of Mobility Management in Cognitive Radio Networks"],"prefix":"10.4018","volume":"10","author":[{"given":"Semba","family":"Yawada","sequence":"first","affiliation":[{"name":"University of Science and Technology, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mesmin J Mbyamm","family":"Kiki","sequence":"additional","affiliation":[{"name":"Beijing University of Technology, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mai Trung","family":"Dong","sequence":"additional","affiliation":[{"name":"University of Science and Technology, Beijing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJTD.2019100102-0","doi-asserted-by":"publisher","DOI":"10.1109\/SIU.2016.7495782"},{"key":"IJTD.2019100102-1","doi-asserted-by":"publisher","DOI":"10.4218\/etrij.17.0116.0850"},{"key":"IJTD.2019100102-2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2016.10.022"},{"key":"IJTD.2019100102-3","doi-asserted-by":"publisher","DOI":"10.1002\/dac.3495"},{"key":"IJTD.2019100102-4","doi-asserted-by":"publisher","DOI":"10.1086\/466549"},{"key":"IJTD.2019100102-5","doi-asserted-by":"publisher","DOI":"10.1109\/PIMRC.2013.6666551"},{"key":"IJTD.2019100102-6","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-015-1023-z"},{"key":"IJTD.2019100102-7","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-014-1661-y"},{"key":"IJTD.2019100102-8","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2018.01.031"},{"key":"IJTD.2019100102-9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2015.10.008"},{"key":"IJTD.2019100102-10","doi-asserted-by":"publisher","DOI":"10.5815\/ijitcs.2013.11.11"},{"key":"IJTD.2019100102-11","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2016.2517619"},{"key":"IJTD.2019100102-12","doi-asserted-by":"publisher","DOI":"10.1109\/IC3I.2014.7019755"},{"key":"IJTD.2019100102-13","unstructured":"Mayekar, N., & Wyglinski, A.
