Thwarting Selfish Behavior in 802.11 WLANs.
Technical Report.

Abstract
The 802.11e standard enables user configuration of
several MAC parameters, making WLANs vulnerable to users
that selfishly configure these parameters to gain throughput. In
this paper we propose a novel distributed algorithm to thwart
such selfish behavior. The key idea of the algorithm is for honest
stations to react, upon detecting a selfish station, by using a
more aggressive configuration that penalizes this station.We show
that the proposed algorithm guarantees global stability while
providing good response times. By conducting a game theoretic
analysis of the algorithm based on repeated games, we also show
its effectiveness against selfish stations. Simulation results confirm
that the proposed algorithm optimizes throughput performance
while discouraging selfish behavior. We also present an experimental
prototype of the proposed algorithm demonstrating that
it can be implementated on commodity hardware.
