Black hole attacks analysis for AODV and AOMDV routing performance in VANETs

VANETs is a wireless technology where vehicles act as mobile nodes to perform a communication network. All mobile nodes in the VANETs can communicate directly each other. As a wireless network, VANETs is vulnerable to some attacks include black hole attack. This kind of attack causes the VANETs service to be out of order. This attack absorbs and drops all of the data packets in the network. The data packets will not reach their destination because interfered by malicious nodes that perform black hole attack. This research will investigate and analyze the impact of the black hole attack on the performance of AODV and AOMDV routing protocols in VANETs. This study uses simulation software to mimic VANETs with multiple nodes. In the simulation scenario, one node acts as a malicious node that performs black hole attack. The result shows that the performance of both routing protocols decreases during the attack. The throughput of both routing protocols reduced while the packet loss increased. Although both routing protocols are vulnerable to black hole attacks, AOMDV has a better performance compared to AODV.
