AN INTEGRATED SCHEDULING ALGORITHM BASED ON USERS’ DIVERSITY FOR COGNITIVE RADIO
The introduction of cognitive radio relieves the pressure brought by the lack of spectrum resources. However, it also brings new problems to the resources scheduling. The currently existed scheduling algorithms have not considered the different identities of primary users (PUs) and secondary users (SUs), delay urgency and implementation progress. Considering the different demands on the spectrum scheduling timeliness, this paper proposes an integrated scheduling algorithm based on users diversity. Simulation results show that the algorithm proposed not only ensures the PUs quality of service but also improves the SUs performance and system throughput. Additionally, the novel algorithm makes the resources allocation between PUs and SUs more fair.
