Spectrum Access Issues and Security in Cognitive Radio Network

Advanced cognitive radio networks (CRNs) are a promising technology. This network functions to solve the issue of scarcity of the radio spectrum by allocating the idle channels. It also carefully allocates the spectrum to unlicensed users in a balanced approach. The expediency of cognitive radio is highly reliant on fair and efficient supervision of the access to the idle portion of frequency channels. This is mainly executed by the network layer and media access control layer of the internet network model. There are various technical and communication issues while intelligently allocation spectrums to high priority and low priority channels. The current article performs a detailed analysis of such challenging issues and technical feasibility of implementing security measures in CRN applications in a systematic order. So, the problem statement of the current research article is a systematic analysis of channel access issues and their proposed solutions using improved protocols.
