In this paper, we investigate the performance of relay selection for simultaneous wireless information and power transfer (SWIPT) systems. In particular, we consider a relay network consisting of both energy harvesting (EH) and nonEH relays. We further assume amplify-and-forward relaying and power-splitting at the EH units. We study the scenarios for both the battery-less and battery-equipped relays. The diversity and coding gains for the battery-less scenario are derived through the outage probability analysis. Our analysis indicates that the relay selection schemes achieve full diversity gain for SWIPT. We corroborate our analysis through simulations and compare the performance of the battery-less and battery-equipped relay scenarios. Moreover, we investigate the effects of the power-splitting on the system performance through simulations.
