Abstract

Cognitive radio sensor networks (CRSNs) can effectively manage communication through clustering. This paper examines Internet of Things Cognitive Radio Sensor Networks. An important step towards a world of smart technology is the Internet of Things (IoT) system based on Cognitive Radio (CR). Many frameworks for creating CR-based IoT systems have been put forth. IoT frameworks based on CR are the main topic of the survey. One possible approach to improving the effectiveness of wireless communication in the Internet of Things (IoT) is the use of Cognitive Radio Sensor Networks (CRSNs). The increasing number of IoT devices cannot be supported by traditional wireless sensor networks due to issues like interference and spectrum constraint. By using cognitive radio technology, CRSNs solve these problems by enabling sensors to dynamically sense, adjust, and use available frequency bands. Although CRSNs have many advantages, there are various difficulties associated with their implementation. Managing the spectrum is still a vital concern, necessitating efficient policies and algorithms to control access to the spectrum and prevent clashes with primary users. Moreover, energy limitations present a challenge because IoT devices need to function effectively within restricted power supplies. Concerns about security, including breaches of data and unauthorized access, necessitate effective countermeasures to safeguard the integrity of the network. This analysis examines the design, essential elements, and operational concepts of CRSNs, emphasizing how they enhance network performance and spectrum efficiency. It talks about the benefits of CRSNs, such as improved energy efficiency, communication dependability, and flexibility under changing conditions. We also examine the difficulties in implementing CRSNs, including spectrum management issues, energy limitations, and security concerns.
