Analysis of Black Hole Attack in MANET on AODV Protocol

Abstract

Mobile Ad-hoc Network (MANET) emerged in the 1970s and is currently widely utilized in social domains. However, black hole attacks pose a significant threat to MANETs. Malicious nodes engage in route falsification to intercept packets from the source node and discard received packets. In this paper, we investigate and analyze black hole attacks on the AODV protocol. Using the NS2 simulation framework, we compare and evaluate the performance in scenarios where the network is subjected to black hole attacks. Simulation results demonstrate that in scenarios with randomly moving network nodes, the performance in terms of successful packet delivery ratio and average delay is superior to scenarios with stationary nodes, despite slight variances that are not substantial.
