This paper investigates the problem of relay selection in simultaneous wireless information and power transfer network, where the relay nodes can harvest energy from received radio frequency signals. The source node transfers energy and information to the relay node through two mechanisms: 1) time switching-based relaying and 2) power splitting-based relaying. In the proposed algorithm, in order to maximize the system throughput, the relay node is selected from the candidate relay nodes depending on the maximum transmission from the relay node to the destination node, the candidate subset consists of the relay nodes with more transmission rate from source node to relay node. Other relay nodes in the subset can keep dormant or continue to harvest energy when the chosen relay node transmits information. The simulation results show that the throughput of the proposed algorithm outperforms the existing algorithm.
