Reactive jamming
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. WebFeb 15, 2024 · Reactive Jammer- Unlike a proactive jammer, which sends data even when no nodes communicate, a reactive jammer starts its operation only when it senses some form of communication in the network. The receiving nodes are blocked, and thus a reactive jammer prevents packets from being received. There are many ways a reactive jammer …
Reactive jamming
Did you know?
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 WebJun 14, 2011 · Reactive jamming attacks are widely regarded as an energy-efficient attack strategy since the jammer is active only when there are data transmissions in the network.
WebReinforcement learning (RL) is being considered for future SATCOM systems due to its inherent capability to self-learn the optimum decision-making policy under different scenarios. This capability enables SATCOM systems to manage their resources judiciously and mitigate jamming attacks autonomously without prior jammer type classification. WebNov 5, 2024 · In this article, we implement a reactive jamming system, JamCloak, that can attack most existing CTC protocols. To this end, we first propose a taxonomy of the …
As the signal is stored in memory, it can be used to create false targets both behind (reactive jamming) and ahead of (predictive jamming) the target intended for protection. Slight variations in frequency can be made to create Doppler (velocity) errors in the victim receiver as well.
