However, in existing works, the problem of secure CSS in mobile cognitive radio networks (CRNs) has not been well considered yet. The detection of abnormal sensing reports in existing works does not evaluate both sensing reports and locations of SUs simultaneously. And the mobility pattern of all SUs is assumed to be similar, which is impractical in real mobile CRNs. In this paper, spatial correlation of the received signal strength among SUs is exploited to get the evidence whether the received signal strength is consistent with the location from where it is generated. And Dempster-Shafer theory is used to filter out abnormal reports by combining the evidence collected from the spatial correlation algorithm in each sensing period. To mitigate the adverse effects caused by the SUs\u2019 mobility pattern, a fusion scheme based on SUs\u2019 reputation is proposed. In comparison to the existing schemes, simulation results demonstrate that the proposed secure CSS scheme improves the primary user detection rate by 10% at false alarm rate of 0.1 when the mobility pattern of the SUs is different. <\/jats:p>","DOI":"10.1155\/2014\/620196","type":"journal-article","created":{"date-parts":[[2014,6,5]],"date-time":"2014-06-05T21:07:51Z","timestamp":1402002471000},"page":"620196","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A Secure Cooperative Spectrum Sensing Scheme in Mobile Cognitive Radio Networks"],"prefix":"10.1177","volume":"10","author":[{"given":"Jun","family":"Du","sequence":"first","affiliation":[{"name":"College of Communications Engineering, PLA University of Science & Technology, Nanjing, Jiangsu 210007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daoxing","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Communications Engineering, PLA University of Science & Technology, Nanjing, Jiangsu 210007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bangning","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Communications Engineering, PLA University of Science & Technology, Nanjing, Jiangsu 210007, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ligang","family":"Shang","sequence":"additional","affiliation":[{"name":"Units 72959 PLA, Jinan, Shandong 250031, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,6,5]]},"reference":[{"key":"B1-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2014.021414.00066"},{"key":"B2-2014-620196","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/141480"},{"key":"B3-2014-620196","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/951205"},{"key":"B4-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2014.022714.130351"},{"key":"B5-2014-620196","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2012.06.006"},{"key":"B6-2014-620196","first-page":"342","volume-title":"Proceedings of the IEEE International Conference on Communications Workshops (ICC \u203213)","author":"Mingchen W."},{"key":"B7-2014-620196","doi-asserted-by":"publisher","DOI":"10.1016\/j.comcom.2012.07.014"},{"key":"B8-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2013.2262008"},{"key":"B9-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2013.031313.121551"},{"key":"B10-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2012.121009"},{"key":"B11-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/JCN.2009.6391387"},{"key":"B12-2014-620196","doi-asserted-by":"publisher","DOI":"10.1109\/GLOCOM.2009.5425380"},{"key":"B13-2014-620196","volume-title":"Proceedings of the Emerging Intelligent Computing Technology and Applications: With Aspects of Artificial Intelligence","author":"Nhan N.
