Mitigating stealthy jamming attacks in low-power and lossy wireless networks.

Jamming in wireless networks has advanced to be more stealthy and long-lasting with limited energy. Stealthy attackers transmit short jamming signals to become less detectable with less energy, and yet powerful enough to ruin entire packet transmission procedures. In this article, we deal with three types of stealthy attacks: `Reactive jamming', `Jamming ACK', and `Fake ACK' attacks. These attacks...
