Abstract

We consider the problem of cooperative intrusion detection in wireless sensor networks where the nodes are equipped with local detector modules and have to identify the intruder in a distributed fashion. The detector modules issue suspicions about an intrusion in the sensor's neighborhood. We formally define the problem of intrusion detection and identify necessary and sufficient conditions for its solvability. Based on these conditions we develop a generic algorithm for intrusion detection and present simulations and experiments which show the effectiveness of our approach.
