Optimal Packet Scheduling in an Energy Harvesting Communication System

The authors consider the optimal packet scheduling problem in a single-user energy harvesting wireless communication system. In this system, both the data packets and the harvested energy are modeled to arrive at the source node randomly. Their goal is to adaptively change the transmission rate according to the traffic load and available energy, such that the time by which all packets are delivered is minimized. Under a deterministic system setting, they assume that the energy harvesting times and harvested energy amounts are known before the transmission starts.
