This paper considers a two-user Gaussian interference channel with energy harvesting transmitters. Different than conventional battery powered wireless nodes, energy harvesting transmitters have to adapt transmission to availability of energy at a particular instant. In this setting, the optimal power allocation problem to maximize the sum throughput with a given deadline is formulated. The convergence of the proposed iterative coordinate descent method for the problem is proved and the short-term throughput maximizing offline power allocation policy is found. Examples for interference regions with known sum capacities are given with directional waterfilling interpretations. Next, stochastic data arrivals are addressed. Finally, online and/or distributed near-optimal policies are proposed. Performance of the proposed algorithms are demonstrated through simulations.read more

Jing Yang,Sennur Ulukus +1 more
TL;DR: In this article, the authors consider the optimal packet scheduling problem in a single-user EH wireless communication system, where both the data packets and the harvested energy are modeled to arrive at the source node randomly and the 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.
