Abstract

This paper propose novel protocol for energy harvesting enabled relaying networks. To evaluate performance, we investigate how the harvested power at relay node affects on signal to noise ratio, outage probability and optimal throughput. Specifically, we develop outage and throughput expression in terms of time and power factors in the proposed time power switching based relaying (TPSR) protocol. A highly accurate closed-form formula of outage probability and throughput are also derived. It is shown that the maximized throughput critically depends on optimal time switching and optimal power splitting coefficients of the proposed protocol. In addition, we compare performance of the energy harvesting protocol in optimal case together with balanced receiver at relay node. The impressive results in this work proved that proposed protocol outperforms power splitting based relaying protocol presented in the literature. The tightness of our proposed protocol is determined through Monte Carlo simulation results. Finally, our results provide useful guidelines for design of the energy harvesting relay node in cooperative networks.
