Comparative study of game theoretic approaches to mitigate network layer attacks in VANETs

For the past few years, number of accidents have occurred due to the rapid usage of vehicles in the road and the lack of emergency alerts provisioning to the vehicle user during natural disasters. VANETs provide an environment to communicate between vehicles to avoid such accidents. Vulnerabilities in the network layer of VANET delays timely traffic data dissemination to the vehicle user. Ensuring security in VANET is very essential for the construction of a robust network for transmission of data. In this paper the game theoretic approaches like co-operative and non-cooperative games for handling security issues in VANET are discussed.
