Nash Equilibrium and Marcov Chains to Enhance Game Theoretic Approach for Vanet Security

Increased reliance on the Internet has made information and communication systems more vulnerable to security attacks in VANET. Instead of designing a defense against an attack, Game Theory attempts to design a defense against a sophisticated attacker who plans in anticipation of a complex defense in VANET. In addition, Game Theory can model issues of trust, incentives, and externalities that arise in security systems. This paper presents a Game theoretic potential for VANET security. The new technique termed NE (Nash Equilibrium) with Markov chains has been computed based on the game model, for VANET security. In this paper, Markov chains (MC) are used to choose the appropriate model for a given security problem in VANET and we have examined this new approach to extend the basic ideas of using game theory in VANET to predict transition rates for enhancing the security. The experimental evaluation will show that the Game theoretic approach of security measures for VANET using NE and MC perform better.
