Novel Intrusion Detection and Prevention for Mobile Ad Hoc Networks: A Single- and Multiattack Case Study

We present novel techniques to counter a set of active attacks, such as denial-of-service (DoS), probe, vampire, and user-to-root (U2R) attacks, in a mobile ad hoc network (MANET) environment for a single- and multiattack scenario. Attacks are detected using a profile (behavior) analysis for single attacks and a distributed trust for multiattacks. A standard ad hoc on-demand distance vector (AODV) routing protocol has been used in a Network Simulator 2 (NS2) environment. We report a maximum accuracy of 87.75% for a single attack and 90.95% for a multiattack scenario.
