Abstract

Mobile Ad Hoc Network (MANET) is one of the largest areas for research and review of the wireless network. Ad Hoc networks of mobile nodes communicate without infrastructure, through radio waves. These networks are used in many fields such as military applications, emergency operations, industrial application, vehicular networks.... An essential requirement in MANET is the security of Ad Hoc networks, Ad Hoc networks more vulnerable to various attacks such as the attack by inundation (Flooding). Flooding is a type of denial of service (DoS) on MANET. Its purpose can lead to overloading of the network, enabling performance degradation, due to movement of invalid packets. In this paper we will try to achieve this type of attack RREQ Flooding as reactive AODV protocol. We analyze in this work the impact of this attack by using the OPNET simulator. Tests show that this type of attack can degrade network performance up to 600%.

Key words: Network, Protocol of routing, AODV, OPNET, Security, Ad Hoc, Flooding, simulation.
