Securing VANET by Preventing Attacker Node Using Watchdog and Bayesian Network Theory

VANET is a type of Ad-hoc network in which nodes movements are limited along roads. To communicate with each other and with road side units, nodes are equipped with radio devices in VANET. VANET are widely used for comfort and safety applications. Authentication of data is important in this kind of application. So security is one of the important factor in VANET. Different kinds of attacks are there in VANET and different techniques are also there to detect and prevent this attack. This paper the authors will identified attacker using watchdog and apply Bayesian filter to avoid/reduce false positive of node, recognized by watchdog.
