Abstract

This paper follows IEEE 802.22 proposed coexistence beacon protocol (CBP), the mechanism carry the information of dynamic resource renting and offering to solve the problem of spectrum sharing for inter-BS (Base Station) coexistence mechanism. Due to high flexibility and low complexity, fuzzy rules based on empirical laws can dynamically adjust parameters to control the radio resources. The fuzzy logic control (FLC) spectrum sharing for Inter-BS coexistence mechanism is chosen to make effective utilization of resources in IEEE 802.22 WRAN. The proposed scheme considers three kinds of traffic, voice, video and data respectively. The simulation results reveal that the proposed scheme can meet the goals of the dynamic spectrum sharing to improve resource utilization and fairness.
