WiSec 2011 Demo: Demonstrating self-contained on-node counter measures for various jamming attacks in WSN

摘要

This paper shortly introduces our real-time jamming detection approach which can be executed on standard wireless sensor nodes. The benefits 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. Our mock-up demonstrator visualises how various attacks of permanent, periodic and random jamming effect RSSI values and how the sensor nodes independently of the location of the jammer reliably indicate ongoing jamming.
