Joint Robust Design for Secure AF Relay Networks With SWIPT

Abstract

 In this paper, we investigate the physical layer security of amplification and transmission networks with simultaneous wireless information and power transmission. Specifically, by looking at the desired dual functional receiver, it is able to decode the information and harvest the energy (EH), assuming that the information can only obtain the status of the incomplete tapping channel, we propose the formation of a common strong joint package, noise Artificial, energy distribution system. We formulate the problem of strengthening the booster energy under both the confidentiality and EH restriction limits, which is not convex and difficult to process. To address this problem, we suggest a two-level improvement approach, which includes research on first dimensions and semi-defined relaxation. In addition, we see that SDRs can get the best solution from the top ranking. The simulation results show that the proposed robust scheme performs better secrecy than other plans.
