WebMay 28, 2024 · This kind of jammer attacks the channel whenever it detects transmission from legitimate radios. With recent advances in self-interference suppression or in-band full-duplex radios, a reactive jammer can jam and simultaneously sense/discern/detect the legitimate transmission. Such a jammer is referred to as a smart reactive jammer. WebThe jamming attacks are prominently categorised into two types , namely (i) responsive jammer and (ii) non-responsive jammer. In the responsive or reactive jamming attack, the …
