Outage Probability Analysis in Multiple-Relay Networks for Wireless Energy Harvesting

Abstract

In this paper, an energy harvesting (EH) amplify-and-forward (AF) multi-relay network is studied, in which the communication between the source node and the destination node is assisted by a number of relays. Furthermore, we adopt a hybrid relaying protocol so-called hybrid power splitting and time switching (HPTS) to allow EH and information processing at relays. To discuss relay selection (RS), we try to achieve the average end-to-end signal-to-noise ratio (SNR). Then, expressions for outage probability and delay-restricted throughput are obtained. It is observed that the system throughput is significantly improved thanks to the change of number of relays.
