摘要：Cognitive Radio Network (CRN) is a promising worldwide network. It meets challenges of efficient spectrum or resource allocation and also lack of spectrum. Efficient resource allocation methodology becomes a new research problem in use of CRN. A most important challenge to this new technology is how to make fair task of available spectrum to unlicensed users. The suitable allocation of idle frequency spectrum coexisting cognitive radioswhile maximizing total bandwidth utilization and diminishing interference is required for the efficient spectrum utilization in CRN. In this article we study the various methods are used to improve the performance, fairness, effective utilization if unused spectrum by secondary network and present the literature survey on cognitive radio networks, spectrum sensing, challenges and different recent methods analysis for resource allocation.
