Influence analysis of grayhole attack to on-demand routing protocol performance on MANET network

Abstract

The on-demand routing protocols AODV and AOMDV operate on the belief that the nodes in the network are friendly. Therefore, they are not designed for security purposes. Attackers have exploited a number of vulnerabilities to perform many forms of cyberattacks, including grayhole attacks, which are similar to black hole attacks but more difficult to detect. This paper focuses on analyzing and evaluating the harmful effects of grayhole attacks on the performance of the on-demand routing protocol. The simulation results on NS 2.35 show that the multipath routing mechanism of the AOMDV protocol can reduce the harm of grayhole attacks compared to the AODV protocol.
