The CRN technology permits the unlicensed operation to be in licensed band. The CRN model poses many challenges in power efficiency, spectrum management, spectrum detection, environment awareness, new distributed algorithm design, distributed spectrum measurements, QoS guarantees, and security. Cognitive radio (CR) is an emerging technology that allows the dynamic deployment of highly adaptive radios that are built upon softwaredefined radio technology. CR has been considered as a main technology for future wireless communications and mobile communication. This paper presents a comprehensive survey on the CRN specifically from the perspectives of applications, network architectures and protocol design issues. First, major applications of the CRN are reviewed. Then, different architectures of the CRN are presented. The unique characteristics of CRN rise to different protocol design issues. These research issues (e.g. spectrum management, interference, routing, security, and location complexity) and the related approaches to address them in the CRN are described.
