Optimal Pricing Effect on Equilibrium Behaviors of Delay-Sensitive Users in Cognitive Radio Networks

This paper studies price-based spectrum access control in cognitive radio networks, which characterizes network operators' service provisions to delay-sensitive Secondary Users (SUs) via pricing strategies. Based on the two paradigms of shared-use and exclusive-use Dynamic Spectrum Access (DSA), the authors examine three network scenarios corresponding to three types of secondary markets. In the first monopoly market with one operator using opportunistic shared-use DSA, they study the operator's pricing effect on the equilibrium behaviors of self-optimizing SUs in a queueing system. They provide a queueing delay analysis with the general distributions of the SU service time and PU traffic using the renewal theory.
