"Webapproach to jamming wireless communication is to employ a reactive strategy. The reactive jam-mer stays quiet when the channel is idle, but starts transmitting a radio signal as soon as it senses activity on the channel. One advantage of a reactive jammer is that it is harder to detect. In our work [4] we implemented the above " - Reactive jamming
