Distributed Denial of Service attack (DDOS) on Vehicular Ad Hoc Networks
(VANETs) is considered to be one of the most serious types of attacks that can be targeted
to those networks. The danger of this attack is in the difficulty of detection becau
se of the
cooperation of several attacking nodes in the network, and its impact on the availability
requirement that is one of the most important security requirements in a network offering
real-time applications .In our research, we study the effect of this attack on VANET
network in the city, taking into consideration two cases. In the first case the target of the
attack is the nodes, while in the second one, the target is the road side units (RSU).
Simulation results have shown that this attack has a significant impact on both cases, by
comparing the basic parameters of the network, such as throughput in/out and the number
of dropped packets, before and after the attack.
