Cognitive Radio Networks: A Social Network Perspective

摘要

Cognitive radio has received various research attention due to its capability of addressing inefficient spectrum usage and spectrum scarcity problems in wireless communications. In this article, cognitive radio networks in respect to social networking is studied and the trust between cognitive nodes in the network is evaluated. Interaction and cooperation amongst cognitive nodes is seen to improve sensing reliability, increased learning and better energy efficiency which in turn enhances the overall network throughput.
