Vehicular Ad-hoc Networks (VANETs) are rapidly emerging networks that are a particularly challenging subset of Mobile Ad Hoc Networks (MANETs). Open medium is one of the main features of VANET due to which it often suffers from security attacks and changing its topology dynamically, lack of management and central monitoring, and there is no clear defence mechanism. In this paper, we investigated the impact of Black Hole attack, Worm-Hole attack and Sybil attack on network performance towards VANET environment. We have also analysed which routing protocol is more vulnerable to the different attacks mentioned earlier in VANET. We have also determined that AODV is the most vulnerable routing protocol to attacks in VANET compared to OLSR routing protocol.
