Optimal Transmission Policies for Multi-Hop Energy Harvesting Systems
IEEE Transactions on Green Communications and Networking, 2018 In this paper, we consider a multi-hop energy harvesting (EH) communication system in a full-duplex mode, where arrival data and harvested energy curves in the source and the relays are modeled as general functions. This model includes the EH system with discrete arrival processes as a special case.
