Power Splitting and Source-Relay Selection in Energy Harvesting Wireless Network

This paper investigates the performance of an energy-harvesting (EH) relay network, where multiple sources communicate with a destination via EH decode-and-forward (DF) relays. The relays all equip power splitter to divide received signal into two parts, which are used for processing and information forwarding, respectively. splitting ratio depicts trade-off between relaying energy decoding energy. We propose optimal joint source-relay selection (OPS-JSRS) scheme power-splitting is obtained best pair selected transmit message. For purpose comparison, we present round-robin (OPS-RR) traditional (TPS-JSRS) schemes. exact asymptotic closed-form expressions outage probability OPS-RR, TPS-JSRS OPS-JSRS schemes derived over Rayleigh fading channels . Numerical results show that lower than OPS-RR schemes, explaining proposed outperforms Additionally, can be improved by increasing number and/or
