Covert communication can prevent the opponent from knowing that a wireless communication has occurred. In the additive white Gaussian noise channels, if we only take the ambient noise into account, a square root law was obtained and the result shows that Alice can reliably and covertly transmit sqrt{n} bits to Bob in n channel uses. If additional “friendly” node closest to the adversary can produce artificial noise to aid in hiding the communication, the covert throughput can be improved. In this paper, we consider the covert communication in noisy wireless networks, where potential transmitters form a stationary Poisson point process.
