Optimal Energy Harvesting Scheme for Power Beacon-Assisted Wireless-Powered Networks

In this paper, we consider one-way relay with energy harvesting system based on power beacon
(PB), in which the relay node harvests transmitted power from the PB station to forward signals to destination.
We also analyse the relay network model with amplify-and-forward (AF) protocol for information cooperation
and Power Splitting-based Relaying (PSR) protocol for power transfer. In particular, the outage probability
and optimal energy harvesting (EH) power splitting fraction of novel scheme in are presented. We obtain
analytical closed-form expression of optimal energy harvesting (EH) power splitting fraction to minimize the
outage probability of system. Using numerical and analytical simulations, the performances of different cases
are presented and discussed.
