Introduction V A E T N • Vehicular ad-hoc network is a special kind of network in which nodes (Vehicles) can communicate with each other on the road and with its Infrastructure. V2I Road Side Unit (RSU) V2V V2V Basic VANET Architecture 2
Safety Applications Non Safety Applications VANET Applications Work Zone Warning:!!! Work Zone Warning:!!! Work in Progress Plz! use Alt. route Shopping MALL ( TESCO ) Parking Slot Available!!! RSU Parking Slot Available!!! 3
VANET Security Requirements • Vehicular network applications require security and the objective of these applications is to serve users and make their journey secure and comfortable. • Attackers have their own role in this network and we cannot predict the dynamic behavior of the attacker. If an attacker works on a safety application and changes the content of the safety message then it poses a very difficult condition on the road and many users will be affected due to this kind of attack. • Accidents are often the result of an alteration of any safety message or the sending of even one wrong safety message in a network and many human lives are at risk [1].

DENIAL OF SERVICE (DOS) ATTACK IN VANET • In VANET, DOS shall not be allowed to happen, where seamless life critical information must reach its intended destination securely and timely. In summary, there are three ways the attackers may achieve DOS attacks. • There are three levels of DOS attacks as described below. • Basic Level: Overwhelm the Node Resources • Extended Level: Jamming the Channel
DENIAL OF SERVICE (DOS) ATTACK IN VANET • Basic Level: Overwhelm the Node Resources
DENIAL OF SERVICE (DOS) ATTACK IN VANET • Extended Level: Jamming the Channel
Conclusion • To achieve secure communication and network availability must be obtained in the VANET set up. In this paper we have discussed the different types of attacks that may be applicable to VANET. • We have proposed a model to provide solution to DOS and • DDOS attacks, which the intention is to ensure network availability for secure communication between the nodes. • It found that network availability has been directly affected in the case of DOS and DDOS attacks, where the attacks has led to most severe impact by causing the network to break down.
