An Overview of IEEE Standardization Efforts for Cognitive Radio Networks

The Cognitive Radio (CR) technology is envisioned as a primary solution for the spectrum scarcity problem in wireless communication networks. Cognitive radio networking allows the exploitation of the unutilized spectrum bands in an opportunistic manner, and thereby, improves the efficiency of the spectrum utilization. Cognitive radio Networks (CRNs) provide wireless connectivity via heterogeneous wireless architectures and dynamic spectrum access techniques. In this paper, we present an overview of the state-of-the-art of the IEEE standardization efforts for CR and CRNs.
