Vehicular Ad-hoc Network systems (VANETs) are a dynamic wireless network where the nodes move randomly without any infrastructure. VANETs are an open transmission and communication media without any security mechanism. So, there are a lot of malicious nodes attacks on VANETs. Blackhole attack is one of the security threats in which the traffic isn’t transmitted to the destination node but will redirect it to a node that actually does not exist in the network to drop that traffic. The main target of the paper is to measure the impact of Blackhole attack on the VANET’s reactive and proactive routing protocols i.e., AODV, DSR, OLSR, and TORA. Simulation is carried out by using OPNET modeler 14.5 [1]. Measurements of different parameters with complete analysis and comparison are presented.
