Intruder Identification and Response Framework for Mobile Ad hoc Networks

Mobile ad hoc networks (MANET) are infrastructure free networks, temporary in nature and without any centralized authority. These unique characteristics coupled with the increased vulnerability of MANET for security attacks demand an immediate solution for securing the ad hoc network, prior to its full-fledged deployment in commercial and military applications. So far, most of the research in MANET has been primarily focused on the routing and mobility aspects rather than securing the ad hoc networks. Due to the ever-increasing security threats, there is a need to develop architecture, algorithms, and mechanisms for a secured ad hoc network infrastructure. Existing intrusion detection approaches (IDA) in MANET suffer from the lack of design and implementation details for intrusion response. To address this limitation, we have proposed an intruder identification and response framework for MANET. Experimental results of the model simulated in NS2 for selected denial of service (DOS) attacks are very promising.
