Resource allocation and game theory
Eric G. Larsson


Game theory is a tool for understanding and analyzing optimization problems that involve more than one, conflicting objective function. In this talk we will review some fundamental concepts from game theory and see how they can be used to analyze resource conflicts that occur in wireless communications networks. A specific application that we will discuss is that of sharing wireless spectrum between multiple, uncoordinated systems. The focus is on physical-layer processing, including power allocation and beamforming with multiple antennas. In the talk we will cover both noncooperative theory (especially the Nash equilibrium) and cooperative game theory (Nash bargaining, in particular).
