Energy-Efficiency Optimization for D2D Communications Underlaying UAV-Assisted Industrial IoT Networks With SWIPT

Zhijie Su et al.

Summary: This article investigates the energy efficiency optimization problem for the Device-to-Device (D2D) communications underlaying unmanned aerial vehicles (UAVs)-assisted Industrial Internet of Things (IIoT) networks with simultaneous wireless information and power transfer (SWIPT). A joint UAV location and resource allocation algorithm is proposed to solve the nonconvex optimization problem involving the UAV's location, beam pattern, power control, and time scheduling. Numerical results demonstrate the significant energy efficiency gain achieved by the proposed algorithm.
