This work presents a novel hybrid model combining an optimal relay selection scheme to incorporate RF energy harvesting in a centralized CSS network. The secondary users, which are equipped with RF energy harvesting capabilities, act as relays in order to forward the sensing information to a fusion center. Here, we have derived an enhanced multi\u2010relay selection strategy to maximize the end\u2010to\u2010end signal\u2010to\u2010noise ratio of the links. Furthermore, a new voting rule is proposed based on the generalized <jats:italic>K<\/jats:italic>\u2010out\u2010of\u2010<jats:italic>M<\/jats:italic> rule, such that it minimizes our objective error function. The performance analysis of our proposed model is presented with respect to the flexible relay positions. We have used complementary receiver operating characteristic curves for analyzing the detection performance of the CSS model with our derived voting rule. Simulation results using MATLAB show that the proposed model gives a better detection probability and a smaller error rate than some related existing works.<\/jats:p>","DOI":"10.1002\/dac.5356","type":"journal-article","created":{"date-parts":[[2022,9,30]],"date-time":"2022-09-30T06:39:55Z","timestamp":1664519995000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A novel relay\u2010aided centralized cooperative spectrum sensing scheme using radio frequency energy harvesting"],"prefix":"10.1002","volume":"36","author":[{"given":"Suvaditya","family":"Majumdar","sequence":"first","affiliation":[{"name":"Department of Electronics and Telecommunication Engineering Jadavpur University  Kolkata India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7091-4743","authenticated-orcid":false,"given":"Chandrima","family":"Thakur","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunication Engineering Jadavpur University  Kolkata India"}]},{"given":"Sudipta","family":"Chattopadhyay","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunication Engineering Jadavpur University  Kolkata India"}]}],"member":"311","published-online":{"date-parts":[[2022,9,29]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.phycom.2010.12.003"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2013.062413.122042"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/JIOT.2020.3026730"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TNSE.2019.2917071"},{"key":"e_1_2_8_6_1","doi-asserted-by":"crossref","unstructured":"SrisomboonK SroulsrunY LeeW.Adaptive majority rule in cooperative spectrum sensing for ad hoc network.
