Demonstrating self-contained on-node counter measures for various jamming attacks in Wireless Sensor Networks

In this paper we shortly introduce our real-time jamming detection approach which can be executed on standard wireless sensor nodes.The benefits of our approach are that no thresholds need to be defined since it detects jamming based on deviations of the Received Signal Strength Indication (RSSI) and the fact that for doing so it needs only 422 Bytes of memory including execution code and stored RSSI values. We implemented a mock-up demonstrator that allows to visualise how various attacks of permanent, periodic and random jamming effect RSSI values and how the sensor nodes in the network independently of the location of the jammer reliably indicate ongoing jamming.
