Energy Efficiency in D2D Cooperative Communication System UAV-Assisted for Energy Harvesting Process at Source and Relay

This work studies a D2D communication AF relaying protocol with UAV assisted to support the harvesting energy process at source and multiple relays by transmitting the RF signal. The best relay is selected by using the Partial Relay Selection (PRS) strategy, and the Time Switching Relaying (TSR) protocol is used for energy harvesting process. From the simulation results, can be shown that the high transmit power of UAV, low altitude of UAV, high value of energy conversion efficiency factor, and time switching factor will result the good energy efficiency (EE) performance.
