Mobile terminals and base stations are being deployed globally resulting in an increase in carbon emissions. Energy harvesting is attracting considerable attention and an environment- friendly communication system is desirable. In this paper, we demonstrate such a system. A power beacon provides energy for a transmitting source and for a relay using time switching radio frequency energy harvesting technique. We demonstrate that when an eavesdropper tries to wiretap the signals transmitted from the source and the relay the system remains secure. The closed-form expression for secrecy outage probability is derived. Our results show how the performance varies with the SNR of the power beacon and the distance from the relay and the source to the power beacon. In addition, we show that the duration of energy harvesting process in relation to the time used for transmitting information has a significant impact on the system security.
