Quality of service-aware coordinated dynamic spectrum access: Prioritized Markov model and call admission control

Abstract:

In this paper, we propose a heterogeneous-prioritized spectrum sharing policy for coordinated dynamic spectrum access networks, where a centralized spectrum manager coordinates the access of primary users (PUs) and secondary users (SUs) to the spectrum. Through modeling the access of PUs and multiple classes of SUs as continuous-time Markov chains, we analyze the overall system performance with consideration of a grade-of-service guarantee for both the PUs and the SUs. In addition, two new ca...
