摘要
Abstract
Dynamic spectrum allocation strategy is one of the key issues of dynamic spectrum management based on cognitive radio. A spectrum allocation algorithms based on game theory with dynamic price adjustment mechanism is proposed to meet the di?versified service transmission requirements of the cognitive users,and protect the legitimate rights and interests of authorized users. The utility function of the game process introduces two parameters,the service priority and the confidence of cognitive users,which are used to jointly control the spectrum price of cognitive users by dynamic spectrum management center. In addition,the influence of user priority on spectrum price varies linearly,while the influence of confidence on spectrum price vsries exponentially. This set?ting is in line with the frequency management requirements of the actual application scenario. The simulation results show that the utility function of the proposed algorithm is more reasonable,and improves the spectrum utilization.关键词
