At this time, cognitive radio (CR) technology came into being, which can provide available spectrum resources for UAVs. However, different from the conventional CR networks, the UAV's location flexibility significantly reduces the spectrum sensing performance and increases the detection delay. Therefore, we propose a Bayesian quickest detection\u2010based spectrum sensing for cognitive UAV networks in this paper. To this aim, we establish a multislot spectrum sensing model in a cognitive UAV network to realize cooperative spectrum sensing (CSS) within the single UAV and avoid disadvantages of cooperation among multiple UAVs. On the basis of this, we make use of Bayesian quickest detection to implement multislot spectrum sensing and evaluate its false alarm probability and detection delay. Further, the tradeoff problem between the false alarm and the detection delay is developed and converted into an optimization stopping time problem. Subsequently, the stopping time problem is theoretically proved and solved. Finally, compared to Bayesian detection, numerical simulation results show that the superiority of Bayesian quickest detection with respect to the false alarm probability and the detection delay is evident, which proves the correctness and effectiveness of the proposed tradeoff problem.<\/jats:p>","DOI":"10.1002\/ett.4750","type":"journal-article","created":{"date-parts":[[2023,3,3]],"date-time":"2023-03-03T03:40:31Z","timestamp":1677814831000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Bayesian quickest detection\u2010based spectrum sensing for cognitive <scp>UAV<\/scp> networks"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8918-3194","authenticated-orcid":false,"given":"Jun","family":"Wu","sequence":"first","affiliation":[{"name":"School of Communication Engineering Hangzhou Dianzi University  Hangzhou City Zhejiang Province China"},{"name":"National Mobile Communications Research Laboratory Southeast University  Nanjing City Jiangsu Province China"},{"name":"Artificial Intelligence Key Laboratory of Sichuan Province Sichuan University of Science and Engineering  Yibin City Sichuan Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cong","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Electronic Information Engineering Wuxi University  Wuxi City Jiangsu Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyu","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Communication Engineering Hangzhou Dianzi University  Hangzhou City Zhejiang Province China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,3,2]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/s19010126"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/978\u2010981\u201016\u20108721\u20101_10"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/s21072408"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ett.4441"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11276\u2010022\u201002931\u2010z"},{"key":"e_1_2_9_7_1","doi-asserted-by":"crossref","unstructured":"MorereP MarchantR RamosF.Sequential Bayesian optimization as a POMDP for environment monitoring with UAVs.
