Cognitive radio network has emerged as a solution to the growing spectrum scarcity and inefficiency problems. However, cognitive radio networks face performance and security bottlenecks due to lack of memory and vast computational capabilities. This problem could be solved if the authors make use of cloud as a central entity for storing spectrum availability information and processing of the spectrum availability data and correctly map the location of the unlicensed user to that of the available spectrum bands. They will be considering only those spectrum bands for communication where the primary users are absent.
