Abstract
On-demand routing protocol is designed to work efficiently on mobile ad hoc networks (MANET). They operate with the belief that all nodes in the network are friendly, thus hackers exploiting security vulnerabilities to carry out some form of cyber attacks, especially Flooding attacks. This form of attack is easily accomplished by overflowing route request packets into the network. Once the attack frequency is large enough, it shall interfere with the route discovery of other network nodes, damaging network performance. In this article, we will analyze and evaluate the impact of flood attacks on the performance of two routing protocols AOMDV. Thereby, we describe a security solutions using the One Time Password (OTP) authentication mechanism (OAM) and implementing AOMDV-OAM security protocol, which is improved from the AOMDV protocol by using OAM to reduce the harmful effects of flood attacks. Using NS2, we assess the security effectiveness of the AOMDV-OAM protocol in random waypoint network topologies where has flooding attacks. Simulation results show that AOMDV-OAM protocol is very effective in minimizing the harmful effects of flood attacks, the rate of successful packet delivery reached over 99% when the one malicious node attacked with a frequency of 20pkt/s and 50pkt/s for Grid network topology.
