Proposed Solutions to Detect and Prevent DoS Attacks on VANETs System

Vehicular Ad hoc NETworks (VANETs) is a network aims to improve road safety by sharing information between vehicles. Security is a major concern regarding critical information shared between vehicles, because information sent over the vehicle network is sensitive and can affect important security decisions. But due to VANET characteristics which is high mobility and its large size, it’s become susceptibility to attacks, especially Denial of Service (DoS) attacks that denial the availability of the network for the users and thus becoming a life crucial. In this paper, we focus on studying the Denial of Service attacks, types and cases on which the attacker may achieve DoS attacks on VANET networks as well as exploring potential solutions in detecting and preventing this attack.
