  Abstract

In this paper, we propose power splitting-based and time-switching-based relaying protocols to solve the energy shortage of sensors and information security at the same time in internet-of-things. A wireless-powered relay uses power splitting or time switching policy to harvest energy from the received RF signals, and it utilizes this harvested energy to forward the received signal to a destination. In addition, a destination transmits jamming signal to prevent an eavesdropper from interpreting data sent by a source while the source sends the data signal. We mathematically derive secrecy outage probability to ensure a predetermined secrecy requirement, and find the optimal power splitting and time switching ratios to minimize secrecy outage probability. Through the simulations under various cases, we confirm that the proposed schemes improve secrecy outage probability, compared to the conventional schemes.
