WebDec 8, 2024 · A reactive jammer is modeled in the simulation, with the goal of disrupting any detected ZigBee transmissions. A means to measure and distribute the reward function and system state to enable edge-learning in this context is presented as part of the implementation. The results demonstrate the effectiveness of our algorithm in mitigating … WebDec 1, 2024 · Reactive jammer 1. Introduction Multiple access and broadcast nature of wireless channels enable the mobility of communication networks. On the other hand, the same nature presents a high vulnerability to attacks on the physical layer such as eavesdropping or jamming [1]. sonic the hedgehog 2 film data
Defeating Smart and Reactive Jammers with Unlimited Power
WebSep 25, 2024 · Reactive jamming is an important type of attack on a physical and medium access control (MAC) layer; such an attack causes the energy of the small devices to be consumed unnecessarily during communication. The performance of resource-constrained networks depends mainly on how efficiently their resources are used in [ 8, 20 ]. WebReactive jammers represent a more sophisticated attack than a constant jammer. As per it’s name, a reactive jammer will sense across the target spectrum (e.g., 868MHz), before transmitting a blocking signal in response to a transmission from a nearby device. Webrandomized jamming behavior; 3) reactive jammer is more effective, energy-efficient and stealthier [3], which is the main focus of this paper. The key feature of reactive jammer is sensing-before-jamming. The jamming reaction time denotes the time dif-ference between the arrival of the original signal and the jamming signal at the receiver. small italian writing desk
