Detection and identification of attacks in Vehicular Ad-Hoc NETwork

Vehicular Ad-hoc NETwork (VANET) is a particular type of the Mobile Ad-hoc NETworks (MANET) and is developed to provide communications in a group of vehicles in range of each other and between vehicles and fixed equipments (Road Side Unit) within a communication range, usually called equipment of the road. This network is very sensible to safety problem. In this work, a new mechanism is proposed to study the safety problem in VANET networks. This mechanism focuses on denial of service (DoS) attacks on the physical and MAC layers in IEEE standard 802.11p. Our proposed solution is used to detect and to identify DoS attacks by using the values of packet delivery ratio (PDR) metric. Simulation results show the acceptable performance.
