Abstract

We study competition between wireless devices in a dynamic setting. We model such systems as non-cooperative stochastic games. Computing the equilibrium behavior of devices in stochastic games is computationally prohibitive, especially when the number of devices are large. To deal with the complexity of such large scale systems, we use an approximate solution concept called the oblivious equilibrium (proposed by Weintraub et. al), where each device reacts to the aggregate state of other devices. We show that under some structural assumptions on the model primitives of the game, the oblivious equilibrium approximates the actual Markov perfect equilibrium. This allows us to compute the equilibrium behavior of these devices in large scale games.
