Abstract

This letter investigates time-sensitive covert communications aided by multiple friendly jammers that intermittently and collectively transmit artificial noise (AN). To maximize communication covertness while satisfying covert throughput and age of information (AoI) constraints, we jointly optimize the transmit probabilities of sensor data and AN. Specifically, we propose a novel differential evolution algorithm based on dynamic Thompson sampling (DE/DTS). By modeling adaptive operator selection as a multi-armed bandit problem, DE/DTS chooses the most suitable operator according to their historical performance. Simulations demonstrate that our scheme outperforms other baselines and reveal that as channel estimation errors increase, the probability for transmitting data becomes higher than that for transmitting AN.
