Abstract

Autonomous wireless multihomed stations (connected to multiple wireless networks) are likely to behave selfishly, trying at the same time to avoid crowded networks, select networks of higher data rates, and use the selected network in a more persistent way than standard MAC protocols prescribe. We analyze the underlying noncooperative game and find its Nash equilibria unsatisfactory. Yet for a repeated version of the game, a strategy of toggling between selfish and honest play can be devised, leading to all stations playing honest and resilient to sophisticated deviations that may seek an unfairly high bandwidth share. Numerical illustration is provided using a multi-WLAN model with each WLAN employing IEEE 802.11 MAC with a different data rate.
