Radio Frequency (RF) energy harvesting and transfer techniques have recently become alternative methods to power the next generation of wireless networks. As this emerging technology enables proactive replenishment of wireless devices, it is advantageous in supporting applications with Quality-of-Service (QoS) requirement. This paper focuses on the resource allocation issues in wireless networks with RF energy harvesting capability, referred to as RF Energy Harvesting Networks (RF-EHNs). First, the authors present an overview of the RF-EHNs, followed by a review of a variety of issues regarding resource allocation.
