One of the most promising and exciting areas of communication technology is Vehicular Ad Hoc Networks (VANETs). It enables vehicles to communicate among and between each other and fixed infrastructures, and, to provide a safe and enjoyable driving experience. However, VANETs are very susceptible to attacks that could easily be evasive due to its dynamic topology, and, resulting in very dramatic results in traffic. To develop a suitable security solution for VANETs, it must first be understand how such attacks could affect the network. Therefore, this study analyzes four different types of attacks against two popular routing protocols (AODV, GPSR) in VANETs. All attacks, blackhole, dropping, flooding, and bogus information, were implemented on two real maps having low and high density. The results clearly show how attacks could severely affect communication and, the need for security solutions for such highly dynamic networks.
