“…100,000 time blocks are used for obtaining the simulation value of the average information rate and the transferred power. The parameters are set similar to those in previous works such as references [1][2][3][4][5][6] and [22], which is proved to be practical. Further, to compare with the performance in the work of [22], the main parameters are set as the same as those in ref.…”

Here, the energy harvesting (EH) relaying node which needs to complete the simultaneous wireless information and power transfer (SWIPT) is considered. The EH relaying node uses the EH technique to get the energy supply and uses the directional transmission to improve the performance of SWIPT. The double discrete‐time‐switch (D‐DTS) based energy harvesting–power transfer–information transmission (EH–PT–IT) protocol is designed. One of the discrete‐time‐switch (DTS) controls the receiver of the EH relaying node and the other controls the transmitter. The performance is analysed by considering the average information rate and the average transferred power. The expressions of the average information rate and the average transferred power are derived analytically. The balanced maximization is considered, and the optimal parameters are obtained analytically. The simulations are presented to verify the analytical results and compare the performance. Comparing with previous works, the SWIPT performance using D‐DTS protocol in this work is better.

“…The path-loss of wireless energy transfer is large and the transmission power of the energy harvesting relaying node is low, which will make the SWIPT performance poor. The simple EH-IT protocols in the previous works can be used for SWIPT [1,5]. The relaying nodes can broadcast energy to different destinations, but the energy transfer decreases due to the path loss.…”

“…Reference [4] analyzed the performance of the EH AF relaying by considering the throughput for Rician fading channels and non-ideal relaying nodes with non-linear amplification and hardware noise. In [5], the performance of EH DF relaying is analyzed in terms of achievable rate for the relaying nodes whose circuit power cannot be neglected, especially the circuit power at decoder and encoder. Reference [6] studied the optimum design of the energy harvesting relay for two-way DF relay networks by applying the max-min criterion for fairness and max-sum criterion for maximum resource utilization.…”

In this article, a relaying network with simultaneous wireless information and power transfer (SWIPT) is considered, where the relaying nodes are energy‐constrained. The relaying nodes rely on energy harvesting (EH) technique for energy supply and they use different directive transmitters for information transmission and energy transfer, respectively, to enhance the SWIPT relaying performance. A novel discrete‐time‐switch and power‐split (DTS‐PS) based energy harvesting mixture transmission (EH‐MT) protocol for each EH decode and forwarding (DF) relaying node is proposed. The expressions for the average information rate and the energy transfer power are derived analytically and verified by simulations. An optimization function is formulated, and the optimal parameters are obtained analytically and verified by simulation.
