QoS-driven pricing policy for cognitive radio networks

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.

Bilişsel radyo ağlar için servis kalitesini esas alan fiyat politikası

Son zamanlarda, gezgin ağ operatörleri (MNO), yüksek veri hızı ve servis kalitesi (QoS) sağlamak için yüksek miktarda spektrum ve bantgenişliğine ihtiyaç duymaktadırlar. Spektrumun daha etkin ve optimum kullanımı için MNO, uygun bir spektrum yönetimi üzerinden kullanılmayan bantları sevk ve idare eder. MNO, önerilen servis kalitesi, servis fiyatı ve ikincil kullanıcıların memnuniyeti arasında bir denge kurması çok önemlidir. Bu çalışmada, bilişsel radyo ağlar için, spektrum isteğinde bulunan ikincil kullanıcıların (RSU) servis kalitesine dayalı olan uyarlanır bir servis yönetimi önerilmektedir. MNO, uzun vadede kendi ağ gelirini ve spektrum kullanımını iyileştirirken RSUlar arasında da spektrum kullanımına bağlı olarak adil bir ücretlendirme yapmasını sağlayan QoS-esas alan bir fiyat politikası geliştirilmiştir. Yoğun ve yoğun olmayan saatlerde dinamik anahtarlama sistemine dayalı RSU ücretlendirme stratejilerinin benzetim sonuçları verilmiştir.
