A new security games based reaction algorithm against DOS attacks in VANETs

Vehicular Networks are an ideal target for various types of rational and non-rational attackers. To cope with, reaction methods against these attacks must exist. In this direction, game theory applied to the security of wireless networks (also known as security games) can be a good way of modeling. In this paper we propose a reaction method against DOS attacks in VANET. In this method we have the choice between two proposed reaction games. Design methodology and defined metrics are inspired from game theory models. To the best of our knowledge, no similar games have been proposed before. The simulations showed the efficacy of our proposal measured by the performance of the obtained results.
