Abstract: The paper derives the secrecy outage probability (SOP) and the probability of strictly positive secrecy capacity (SPSC) for wireless networks with energy harvesting. The Base Station (BS) uses the received RF signal to harvest energy. The harvested energy is used to transmit data to the receiver R. The eavesdropper E receives the signal from BS and try to decode it. We also derive the SPSC and SOP when there are K relay nodes. The best relay is selected to amplify the BS signal to the receiver R.

Keywords: PLS; physical layer security; SOP; secrecy outage probability; SPSC; probability of strictly positive secrecy capacity; energy harvesting using radio frequency (RF) signals; Rayleigh channels; outage probability; CDF of SINR; PDF of SINR.
