Optimal Broadcast Scheduling for an Energy Harvesting Rechargeable Transmitter With a Finite Capacity Battery
The authors consider the minimization of the transmission completion time with a battery limited energy harvesting transmitter in an M-user AWGN broadcast channel where the transmitter is able to harvest energy from the nature, using a finite storage capacity rechargeable battery. The harvested energy is modeled to arrive (be harvested) at the transmitter during the course of transmissions at arbitrary time instants. The transmitter has fixed number of packets for each receiver. Due to the finite battery capacity, energy may overflow without being utilized for data transmission. They derive the optimal offline transmission policy that minimizes the time by which all of the data packets are delivered to their respective destinations.
