Smart Grid: ReCognize – Reliable Cognitive Radio Networks for the Smart Grid

We propose the JIM-Beam — Jamming and Interference Mitigation using Beam-forming antenna — flooding protocol that uses directional antennas to mitigate the jamming attack.  Similar to how an uncoordinated frequency hopping (UFH) transceiver randomly selects its frequency channel to escape from persistent jamming on a single channel, a JIM-Beam transceiver randomly reorients its directional antenna to escape from jamming from a single point in space.  Our simulation shows that JIM-Beam can significantly outperform UFH.  We presented our findings in the MobiHoc 2012 conference.
