Analytical Survey of Active Intrusion Detection Techniques in Mobile Ad Hoc Networks

The mobile ad hoc network (MANET) is an infrastructure less system, comprises of mobile devices connected by wireless medium. MANET data communication undergoes various violation and prohibition issues by its mobile nodes, due to different access and information flow requirement across the network. In addition intermittent connectivity of wireless network and mobile device failures cause security lapses in the MANET communication, further leads to intruder’s generating multiple attacks.. Intrusion detection gets more significant in current MANET security research works. Furthermore due the open forum of MANET may change the system topology by suspecting attacks like inactive eavesdropping, dynamic impersonation and denial of services. To avoid all the problems created by an intruder, a successful MANET is implemented based on its security. The security research in MANET has been paying attention on key managing, routing protocol and intrusion detection techniques. The rating on intrusion detection and supportive layer in MANET has provided with a resolution to extend it to the real world applications. The active intrusion detection system aims to revise the various intrusion detections and prevention systems predicted for Mobile Ad hoc Networks (MANETs) and also compare the latest techniques of Intrusion Detection dependent on their architecture and data gathering techniques.
