Radio-Based Cooperation for Wireless Intrusion Detection

This paper presents an approach for wireless intrusion detection based on signal analysis with wavelet transform. The main function of this approach is performed by an entity called radio supervisor, which can be implemented in any node of the wireless network. Radio supervisor is also able to detect distributed attacks by cooperating with other radio supervisors via a signal-based correlation scheme that we provide for the circumstance. Finally, functions and features of the proposed approach are studied through simulations.
