WebJun 6, 2011 · Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access: the policy that addresses the spectrum scarcity problem that is encountered in many countries. Thus, CR is widely regarded as one of the most promising technologies for future wireless communications. To make radios and wireless networks … Webexperience scarcity in spectrum. Ac cor di ng to recent studies it is pr ove d that this scarcity is observed due to static spectrum allocation policy. [2] In cognitive radio networks (CRN), Dynamic spectrum access (DSA) is solution for this spectrum scarcity which arises due to static spectrum allocation policy.
