Center node: "methodologies for analyzing equilibria in wireless games"
  Abstract: Non exhaustive methodologies for characterizing equilibria in wireless games in terms of existence, uniqueness, selection, and efficiency are provided. The paper will focus on technical problems arising at the physical and medium access layers of a wireless network, and not on economic aspects related to it, like the auction problem for spectrum, even though it is also an important scenario where game theory is used.
