Performance analysis and optimization of a hybrid TSR–PSR protocol for AF, DF and hybrid AF–DF relaying under Weibull fading

In this paper, a generalized Interference-aided radio frequency energy harvesting (EH) cooperative network has been presented under Weibull faded environment. The performance analysis of the system in terms of Throughput and Outage Probability for various cooperation protocols, Decode-and-Forward, Amplify-and-Forward and Hybrid-Decode-Amplify-Forward has been shown. The throughput of the network has been optimized with respect to the EH fractions of the hybrid TSR–PSR protocol. Integral-form expressions for Outage probability and Throughput are derived for the given protocols. In addition, the throughput of the proposed network has been evaluated under different channel conditions which show the superiority of different EH fractions in different relays. Analytical expressions have been well substantiated through extensive simulation results. The influence of system parameters such as time switching and power splitting fractions, number of relay nodes, channel parameters on outage probability and throughput performance of the proposed network has been shown. Finally, the throughput of the proposed model has been compared with various benchmark techniques.
