Game Theory Based Resource Allocation for Cognitive Radio Networks

In this paper, the authors develop an optimal solution for resource allocation between secondary users in a Cognitive Radio Network (CRN). They assume a CRN that contains a set of Primary Users (PUs) coexisting with Secondary Users (SUs) in an underlay spectrum sharing paradigm. PUs use licensed bands of the spectrum while SUs try either to use unoccupied bands or coexist with PUs in the same band without harmfully affecting primary transmissions. They propose an algorithm based on the VCG (Vickrey - Clarke - Groves) model in a non cooperative game for spectrum allocation between secondary transmissions that guarantee a required minimum data rate for both PUs and SUs, assuming a fixed value of the bit error rate.
