"Observations from the Sandbox: Cooperative and Non-Cooperative Games in Wireless Networks"

User cooperation in heterogeneous wireless networks has recently great attention recently as a methodology by which to improve capacity in interference limited scenarios. However nodes in heterogeneous networks are controlled by different entities and voluntary cooperation cannot be assumed unless the cooperation results in individual benefits. The need for studying such self-organizing and decentralized networks has resulted in the exploration of suitable game theoretic tools to analyze and predict the interactions of nodes in such networks. In this talk, we will first present game-theoretic models for the MIMO multiple access and broadcast channels with the goal of determining the existence and uniqueness of equilibrium points. Uniqueness of equilibria ensures there is a single operating point for the network. Building on the game theoretic models, the question of whether cooperation among rational users can be taken for granted is addressed and the regimes under which cooperation can be voluntarily assumed are characterized.
