Routing Attacks in Vanets

Abstract

Now-a-days many accidents are taking place due to inefficient drivers, traffic congestion, violation of traffic laws, inadequate road information, increased automobile usage, and due to lack of security assured infrastructure. With the help of intelligent road transportation system, researchers and industry people are enhancing the vehicular communication to reduce the number of accidents. VANET is a sub class of MANET, which is a very promising and latest technology. Security means protecting the privacy (confidentiality), availability, integrity and non-repudiation. Security implies the identification of potential attacks, threats and vulnerability of a certain system from unauthorized access, use, modification or destruction. A security attack is any action that compromises or bypasses the security of information illegally or in an unauthorized way. In this paper, the need for security, different possible attacks in VANETs and how to overcome them are presented.
