Covert Transmission Control Scheme with High Reliability and Anti-Jamming for IoT

As the mainstay of the Internet of Things (IoT), data carries the vital memory of the future intelligent society. However, because of the inherent broadcast and open characteristics of wireless channels, transmitting data securely and reliably is a huge challenge for IoT. In this paper, a covert transmission control scheme with high reliability and anti-jamming capability is proposed to deal with the above challenges, by exploiting the artificial noise emitted by cooperative interference sources in the environment. Specifically, with the aim of maximizing the warden's detection error probability, the transmit power and frequency are jointly optimized under the constraints of transmission reliability and channel equivocation. The Block Coordinate Descent (BCD) algorithm is used to solve the formulated optimization problem. Numerical results demonstrate the superiority of our proposed scheme, which can simultaneously achieve high reliability, covertness, and anti-jamming capability.
