Cognitive radios (CR) have a great potential to improve spectrum utilization by enabling users to access the spectrum dynamically without disturbing licensed primary users. Spectrum management is an important issue for spectrum sharing. The focus of this paper is spectrum management in secondary network, considering a non cooperative framework. Price utility function based power allocation will be analyzed and robust optimization will be involved in this paper.
