Wireless Powered Communication Networks With Non-Ideal Circuit Power Consumption [PDF]
IEEE Communications Letters, 2017 Assuming non-ideal circuit power consumption at the energy harvesting (EH) nodes, we propose two practical protocols that optimize the performance of the harvest-then-transmit wireless powered communication networks (WPCNs) under two different objectives: (1) proportional fair (PF) resource allocation, and (2) sum rate maximization.
