[en] Simultaneous wireless information and power
transfer (SWIPT) and full-duplex (FD) have emerged as prominent technologies to overcome limited energy re sources and improve spectral efficiency (SE) in Internet-of Things (IoT) networks. This article investigates the outage and throughput performance for a decode-and-forward (DF) relay SWIPT system, which consists of one source, multiple relays, and one destination. Herein, the relay nodes can harvest energy from the source’s signal and operate in the FD mode. Further, a sub-optimal, low-complexity, yet efficient relay selection scheme is proposed. Specifically, one relay is selected to convey information from a source to a destination so that it achieves the best channel from source to relays. Then, by considering two relaying strategies, termed static power splitting-based relaying (SPSR) and optimal dynamic power splitting-based relaying (ODPSR), performance analysis in terms of outage probability (OP) and throughput are performed for each one. Notably, the independent and non-identically distributed (i.n.i.d.) Rayleigh fading channels are considered, which poses new challenges for obtaining analytical expressions. In this context, we derive exact closed-form expressions for the OP and throughput of both SPSR and ODPSR schemes. Moreover, the optimal power splitting ratio of ODPSR is obtained to maximize the achievable capacity at the destination. Finally, extensive numerical and simulation results are presented to confirm our analytical findings. Both the simulation and analytical results show the superiority of ODPSR over SPSR. | |
