A Novel Architecture for Mitigating the Manet Routing Attacks

Abstract: A mobile ad hoc network is a network with many free or autonomous nodes comprised of mobile devices or mobile pieces that arrange themselves in different ways operating without specific network administration. Mobile Ad Hoc Network (MANET) is unique by virtue of its self configuring and optimizing nature. Due to its flexible nature MANET is exposed to different types of attacks, mainly routing attacks. Attack Prevention methods like encryption, intrusion detection system, intrusion prevention system can be used for reducing certain attack possibilities. An Intrusion detection system monitors and analyses the activities of the nodes and determines the performance with the security rules. It also alerts the neighboring nodes if irregularity has been detected in the performance of a node. An intrusion Response System recovers the affected services and reconfigures the system. As topology of MANET changes continuously achieving security in these networks is very difficult.

Keywords: Ad hoc networks, intrusion detection system, intrusion response, routing attacks.
