Abstract: Information received by a vehicle in a Vehicular Ad-hoc Network (VANET) can either be regular messages from normal sender vehicles or fraudulent messages from malicious senders. Accepting malevolent messages from malicious sender would result in the receiver vehicle processing erroneous information, while discarding genuine normal messages would result in loss of valuable information. Therefore, in absence of a corroborating mechanism to verify the type of the sender vehicle (normal or malicious), the receiver vehicle is faced with a dilemma of either accepting or discarding the received information. This paper aims to address this issue by modeling the interaction between the pair of communicating vehicles in VANET as a two player incomplete information extensive form game. Various vehicular attributes such as the detection rate & false alarm rate of the IDSs operating on vehicles, reputation values of vehicles, priority levels of the messages being exchanged etc., are used to formu late the Bayesian Nash Equilibrium (BNE) based messages accepting strategies for the receiver vehicle. Empirical results show that the proposed game theory based framework significantly reduces the dissemination of false information in the vehicular network by enforcing the malicious sender vehicles (attackers) into adopting a constrained set of less malevolent strategies.
