Fair efficient and power-optimized spectrum sharing scheme for cognitive radio networks Saleem Aslam and Kyung Geun Lee Department of Information and Communication Engineering Sejong University Seoul Republic of Korea Corresponding author kglee@sejong.ac.kr Email address SA saleem83@nrl.sejong.ac.kr Abstract The cognitive radio network CRN is a promising solution to the problem of spectrum scarcity. To achieve efficient spectrum utilization cognitive radio requires a robust spectrum sensing and spectrum sharing scheme. Therefore spectrum sharing scheme plays a key role in achieving the optimal utilization of the available .
