Competitive and Fair Medium Access Despite Reactive Jamming

Intentional interference constitutes a major threat for communication networks operating over a shared medium where availability is imperative. Jamming attacks are often simple and cheap to implement. Today's jammers can perform physical carrier sensing in order to disrupt communication more efficiently, especially in a network of simple wireless devices such as sensor nodes, which usually operate over a single frequency (or a limited frequency band) and which cannot benefit from the use of spread spectrum or other more advanced technologies.
