A Wireless Intrusion Detection System for Secure Clustering and Routing in Ad Hoc Networks

Intrusion detection and secure routing schemes have been proposed for increasing the security and reliability in critical scenarios like mobile ad hoc networks. In this paper we present an integrated secure routing system based on Intrusion Detection Systems (IDS) and SUCV (Statistically Unique and Cryptographically Verifiable) identifiers. The proposed IDS has been used for the support of secure AODV routing, named IDS-based Secure AODV (IS-AODV), in a wireless ad hoc network scenario. Our IDS solution is based on the detection of behavior anomalies on behalf of neighbor hosts, with passive reactions, aiming to create a cluster whose route paths will include only safe nodes, eventually. We implemented a simulation model to test the effects and overheads of the proposed IDS scheme when defending the AODV routing functions. Results show that the proposed IDS is effective in isolating byzantine hosts, and it assists the AODV secure routing scheme to converge in finding end-to-end safe routes.
