Optimal Scheduling and Beamforming in Relay Networks With Energy Harvesting Constraints

Shimin Gong, Lingjie Duan, Natarajan Gautam
2016 IEEE Transactions on Wireless Communications  
Due to the relays' inability to harvest energy and transmit data simultaneously, the source needs to optimally schedule the relays' energy harvesting (EH) and data transmission.  ...  In this paper, multiple relays capable of harvesting energy from radio-frequency (RF) signals are employed to collaboratively forward data from a source transmitter to its destined receiver.  ...  Hence, cooperative communications may provide a network-level solution to balance the use of harvested energy in different EH devices.  ...
