This study proposes an efficient spectrum\u2010sharing technique for dual\u2010hop CRNs using NOMA, optimized by an improved artificial bee colony (IABC) algorithm and guided by a single\u2010input single\u2010output fuzzy rule\u2010based system (SISO\u2010FRBS). In this setup, a distant primary transmitter communicates with the primary receiver via a secondary NOMA relay. The objective is to maximize the sum data rate of secondary users (SUs) while minimizing total transmission power. SISO\u2010FRBS enhances the IABC search process by dynamically guiding the search agents, improving both optimization quality and convergence. Simulation results show that the proposed scheme achieves the primary data rate benchmark of 5\u2009bit\/s\/Hz at a transmit power of 19\u2009mW, compared with 23\u2009mW with traditional ABC, achieving a 19.04% improvement in power efficiency.<\/jats:p>","DOI":"10.1155\/acis\/8168986","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T10:55:39Z","timestamp":1757415339000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficient Spectrum Sharing in Cognitive Radio Networks With NOMA Using Computational Intelligence"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6204-4146","authenticated-orcid":false,"given":"Kiran","family":"Sultan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,9]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/jsyst.2021.3131122"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/access.2021.3123577"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jksuci.2022.08.013"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2024.3521647"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/ojcoms.2021.3069801"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/msp.2018.2789521"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.phycom.2022.101711"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2022.3185545"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/9713450"},{"key":"e_1_2_9_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/comst.2018.2835558"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/access.2019.2895645"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2022.3146552"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.32604\/cmes.2023.023897"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.4316\/aece.2023.02002"},{"key":"e_1_2_9_15_2","doi-asserted-by":"crossref","unstructured":"MetreP.
