Denial of Service (DOS) Attack and Its Possible
Solutions in VANET

Introduction

• 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.

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

ANALYSIS AND DISCUSSION

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.
