Game Theory in MATLAB for Cognitive Radio Networks

A game-theoretic MATLAB model for cognitive radio (CR) systems supporting dynamic spectrum access, featuring multi-hop networks with CR nodes that realistically emulate physical and administrative structures. This research investigates user communication sessions through cross-layer optimization, integrating power control with joint scheduling and routing mechanisms. The approach analyzes channel quality and spectrum substitutability while establishing utility functions for secondary users' spectrum requirements. The MATLAB implementation includes a spectrum admission pricing scheme demonstrating near-optimal performance in most scenarios through equilibrium analysis.
