Recently, a large amount of spectrum and bandwidth are demanded by mobile network operators (MNOs) in order to obtain the high data rates quality of service (QoS). For optimal spectrum utilization for better efficiency, MNO should handle unused spectrums through a convenient spectrum management. Significantly, MNOs should trade-off among the proposed QoS, service pricing and secondary users' (SUs) satisfaction. In this study, adaptive spectrum management based on the requesting SUs' (RSUs) QoS requirement is proposed in cognitive radio network (CRN). QoS-driven pricing policy is developed so that MNO charges RSUs fairly while improving spectrum utilization and network revenue (NR) efficiency in the long term. Simulation results illustrate the RSUs charging strategy based on dynamic switch system in off-peak and peak hours.

“…The proposed pricing policy is implemented in our previous framework, Instant overbooking framework for CRN (IOFCR) [10]. The main part of this work is providing optimal spectrum allocation via providing high RSUs QSL and balance the total revenue (TR) in both off-peak and peak hours based on dynamic switch system in the long term [11].…”

In recent years, there has been a rapid evolution of wireless technologies that has led to the challenge of high demand for spectral resources. To overcome this challenge, good spectrum management is required that calls for more efficient use of the spectrum. In this paper, we present a general system, which makes a tradeoff between the spectral efficiency (SE) and energy efficiency (EE) in the cellular cognitive radio networks (CCRN) with their respective limits. We have analyzed the system taking into account the different types of power used in the CCRN, namely the spectrum detection power (Zs) and the relay power (Zr). Optimal policy for emission power allocation formulated in the function of sub-channel activity index (SAI) as an optimization problem in order to maximize spectrum utilization and minimize the energy consumption in the base station of the secondary system energy consumption, is subject to different constraints of the main user system. We also evaluate the collaborative activity index of the sub-channel describing the activity of the primary users in the CCRN. The theoretical analyses and simulation results sufficiently demonstrate that the SE and EE relationship in the CCRN is not contrary and thus the achievement of optimal tradeoff between SE and EE. By making a rapprochement with a cognitive cellular network where SBSs adopts an equal power allocation strategy for sub-channels, the results of our proposed scheme indicate a significant improvement. Therefore, the model proposed in this paper offers a better tradeoff between SE and EE.
