Linear and Nonlinear Energy Harvesting in Concurrent Cellular and D2D Communication

Engineering Reports, Volume 7, Issue 9, September 2025.
In this study, an interference‐aided dual‐hop cooperative communication scenario is considered, where both cellular and energy‐constrained device‐to‐device (D2D) users coexist and share the same radio resources. The performance of the proposed model is studied considering both linear and nonlinear EH models employing time‐switching and power‐splitting ...

SWIPT for wireless cooperative networks

Electronics Letters, 2015
Simultaneous wireless information and power transfer (SWIPT) in wireless cooperative networks is studied, where multiple source–destination pairs establish a communication link via an energy harvesting (EH) relay. The relay employs a power splitting (PS) scheme to harvest the energy sent from each source, which it uses to forward the transmissions to ...

Buffer‐Aided Cooperative NOMA: An Energy‐Efficient Design

IET Communications, Volume 19, Issue 1, January/December 2025.
In this paper, we propose a buffer‐aided cooperative NOMA‐SWIPT scheme for multi‐user systems. We consider the optimization of the long‐term power minimization problem under the imperfect channel state information. Simulation results reveal the trade‐off relationship between the average power consumption and the average queuing delay.
