Reactive jamming
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 adversary targets certain frequency bands depending on cognitive radio (CR) users’ activity. WebJamming attacks can be divided into constant, random, deceptive, reactive, and frequency-sweeping attacks (Pirayesh and Zeng, 2024). Constant jamming attacks paralyze the bandwidth by transmitting a continuous signal regardless of the carrier-sense multiple access (CSMA) protocol.
