具有约束条件的认知无线电网络最优频谱价格函数
Optimal Pricing Function with Spectrum Constraint in Cognitive Radio Networks
摘要
Abstract
ProtectingtheQuality-of-Service(QoS) of the primary user is very inportant in cognitive radio networks. In this paper, a practical constraint is considered that the available spectrum for the secondary users is limited in opportunistic specurum sharing. An optimal pricing function is derived,which can provide QoS-guaranteed for the primary users and more revenue for the primary service provider. Moreover, some practical environment parameters ( such as channel quality, traffic fluctuation) are taken into account in spectrtun pricing. In dynamic scenarios, the price can converge to the optimal value by iteration. Simulation results show that the QoS of the primary user can be guaranteed in the proposed pricing, while the profit is not less than that in market-e-quilibrium-based price.关键词
