Ad hoc multi-WLAN: A game-theoretic model of correlated play

Wireless multihomed stations (i.e., connected to multiple wireless networks, possibly of heterogeneous data rates) are likely to select networks of higher data rates and use them in a persistent way. We analyze the underlying noncooperative game and find its Nash equilibria. For a corresponding repeated game, correlated equilibrium play by honest stations (concerned with fairness and overall bandwidth utilization) is found to eventually lead to fair and efficient bandwidth distribution, while discouraging even sophisticated long-term deviations.
