The document discusses vehicular ad-hoc networks (VANETs), highlighting the communication between vehicles and infrastructure for safety and non-safety applications. It addresses the potential threats from attackers that could compromise safety messages, resulting in severe risks for users on the road. The paper proposes a model aimed at preventing denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks to ensure secure communication and network availability.
![ 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].](https://image.slidesharecdn.com/dosattackinvanet-210202103800/85/Denial-of-Service-DOS-Attack-and-Its-Possible-Solutions-in-VANET-4-320.jpg)

- 7. 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. 1. Basic Level: Overwhelm the Node Resources 2. Extended Level: Jamming the Channel
- 8. Basic Level: Overwhelm the Node Resources
- 9. Extended Level: Jamming the Channel
- 14. 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.
