Game Theory in MATLAB for Cognitive Radio Networks

To address dynamic spectrum access requirements in cognitive radio (CR) systems, we developed a non-cooperative game theory model using MATLAB that identifies physical and administrative structures in multi-hop networks with CR nodes, providing enhanced realism for practical deployment scenarios. Our MATLAB implementation employs cross-layer optimization techniques to improve user communication sessions, combining power control algorithms with coordinated scheduling and routing mechanisms. The code specifically incorporates channel quality assessment and spectrum substitutability analysis, implementing a utility function that calculates secondary users' spectrum demand based on QoS parameters. Furthermore, for spectrum admission opportunities, we programmed a pricing strategy in MATLAB that utilizes equilibrium analysis to demonstrate near-optimal performance across most operational conditions, with the algorithm continuously adjusting prices based on spectrum availability and user demand patterns.
