Abstract According to a recent study, adding intelligent reflecting surfaces (IRS) to propagation environments improves the performance of wireless devices. The capabilities of cognitive radio’s spectrum sensing over environments with assisted wireless propagation via IRS are examined in this research. Taking channel fading effects into consideration, we derive closed-form analytical expressions for the average probability of detection (APD) for single user and cooperative users. Further, the derived APD expression is used to derive the average area under the receiver operating characteristics curve ( $${\overline{AUC}}$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mover> <mml:mrow> <mml:mi>AUC</mml:mi> </mml:mrow> <mml:mo>¯</mml:mo> </mml:mover> </mml:math> ) expression. Monte Carlo simulations are also carried out in order to validate the derived expressions. Results demonstarte the extent of detectability performance in cognitive radio on utilizing the IRS aided wireless propagation environment therefore witnessing its significance for upcoming wireless technological advancement by offering spectrum efficiency with good quality of service (QoS).

The International Journal of Wireless Information Networks serves as an international forum for researchers in the telecommunications and computer industries to disseminate knowledge related to wireless information networks. This distinguished quarterly publishes high-quality, peer-reviewed original papers covering applications such as sensor and mobile ad hoc networks, wireless personal area networks, wireless local area networks, mobile data networks, location-aware networks and services, as well as radio frequency localization and RFID technologies. The journal also addresses performance prediction methods, radio propagation studies, modulation and coding, multiple access techniques, security and privacy considerations, antenna and RF subsystem design, VLSI and ASIC design, experimental testing, traffic and frequency management, and network signaling and architecture. Published papers are categorized into four types: invited papers (reviewing current and future directions), overview reports (elaborating on standards and technical details of field trials), technical papers (presenting specific technical contributions of archival value), and letters (enhancements to previously published works, statements of unresolved issues, comments and corrections on published papers). The International Journal of Wireless Information Networks aims to meet the needs of academic researchers engaged in fundamental research, telecommunications and computer engineers involved in the design, planning, operation, and maintenance of cutting-edge wireless information networks, as well as the telecommunications and computer technology community participating in applied research and standardization activities.
