چکیده

A new emerging solution to prolong the lifetime of the energy-constrained wireless networks is energy harvesting. In this paper, an Amplify-and-Forward (AF) relaying network in downlink phase is proposed. The relay harvests energy through Free Space Optical (FSO) link from the source and uses it to forward information to the destination through the RF link. In addition, there is a direct RF link between the source and destination. The FSO link experiences Gamma-Gamma atmospheric turbulence conditions with pointing errors and Rayleigh fading is considered for RF channels. In this system, a closed-form expression for outage probability in the form of Meijer’s-G function is derived.
