Abstract

This paper considers an energy harvesting (EH) relay network in which the relay node harvests energy using the hybrid EH protocol, which is a composite of power-splitting (PS) and time- switching (TS) protocols. As an energy storage may help to reduce the randomness of the energy availability at the relay, we consider two cases; i) the relay does not have a long-term energy storage, and ii) the relay has an infinite capacity long-term energy storage. By maximizing the average success probability, the optimal PS ratio is analytically derived, and the optimal TS ratio is numerically calculated based on the optimal PS ratio. Numerical results of the success probability are validated with simula..
