Bankrupting the jammer

The high vulnerability of nodes in a WSN to jamming arises from the low resilience to jamming signals, easy differentiability of packet types and high predictability of wakeup schedules. In this paper, we propose Jam-Buster - a jam-resistant solution for a single channel WSN that increases resilience by using multi-block payload, eliminates differentiation by using equal size packets and reduces predictability by randomizing the wakeup times of the sensors. While each of these individual components is quite simple, the combination of the three components results in a jam-resilient system that forces the jammer to spend more energy to be effective and so reduce its own lifetime.
