MAC Layer Jamming Mitigation Using a Game Augmented by Intervention


MAC layer jamming is a common attack on wireless networks, which is easy to launch by the attacker and which is very effective in disrupting the service provided by the network. Most of the current MAC protocols for wireless networks, for example, IEEE 802.11, do not provide sufficient protection against MAC layer jamming attacks. In this paper, we first use a non-cooperative game model to characterize the interactions among a group of self-interested regular users and a malicious user. It can be shown that the Nash equilibrium of this game is either inefficient or unfair for the regular users. We introduce a policer (an intervention user) who uses an intervention function to transform the original non-cooperative game into a new non-cooperative game augmented by the intervention function, in which the users will adjust to play a Nash equilibrium of the augmented game. By properly designing the intervention function, we show that the intervention user can effectively mitigate the jamming attacks from the malicious user, and at the same time let the regular users choose more efficient transmission strategies. It is proved that any feasible point in the rate region can be achieved as a Nash equilibrium of the augmented game by appropriately designing the intervention.
