Physical Layer Secrecy in the Wireless Power Transfer Network with Full-Duplex Jamming

This paper investigates the secrecy performance for wireless communications with energy harvesting and full-duplex (FD)jamming. In order to improve the secrecy performance, the receiver works in the FD manner that it receives data and transmit jamming signals simultaneously. The transmit powers for both data and jamming signals are harvested from nearby energy-harvesting-base-stations (EHBSs). The EHBSs and eavesdropper are randomly located, following the Poisson Point Process (PPP)and Binomial Point Process (BPP), respectively. The secrecy outage probability of the proposed system is successfully derived. The analysis is verified with numerical Monte Carlo simulations. The result shows that the applying the full-duplex jamming and energy harvesting enhances the secrecy performance of the wireless network.
