Detection of Reactive Jamming in Sensor Networks
An integral part of most security- and safety-critical applications is a dependable and timely alarm notification. However, owing to the resource constraints of wireless sensor nodes (i.e., their limited power and spectral diversity), ensuring a timely and jamming-resistant delivery of alarm messages in applications that rely on wireless sensor networks is a challenging task. With current alarm forwarding schemes, blocking of an alarm by jamming are straightforward and jamming is very likely to remain unnoticed. In this paper, the authors propose a novel jamming detection scheme as a solution to this problem.
