Optimal Radio Frequency Energy Harvesting With Limited Energy Arrival Knowledge [PDF]
IEEE Journal on Selected Areas in Communications, 2016 In this paper, we develop optimal policies for deciding when a wireless node with radio frequency (RF) energy harvesting (EH) capabilities should try and harvest ambient RF energy. While the idea of RF-EH is appealing, it is not always beneficial to attempt to harvest energy; in environments where the ambient energy is low, nodes could consume more ...
