报告摘要：

Energy harvesting (EH) is a promising technique to fulfill the long-termand self-sustainable operations for Internet of things (IoT) systems.In this paper, we study the joint access control and battery predictionproblems in a small-cell IoT system including multiple EHuser equipments (UEs) and one base station (BS) with limited uplink accesschannels.Each UE has a rechargeable battery with finite capacity.The system control is modeled as a Markov decision process without complete priorknowledge assumed at the BS, which also deals with large sizes in both state andaction spaces.First, to handle the access control problem assuming causal battery and channelstate information,we propose a scheduling algorithm that maximizes the uplink transmissionsum rate based on reinforcement learning (RL) withdeep Q-network (DQN) enhancement.Second, for the battery prediction problem,with a fixed round-robin access control policy adopted,we develop a RL based algorithm to minimize the prediction loss(error) without any model knowledge about the energy source and energy arrivalprocess.Finally, the joint access control and battery prediction problem isinvestigated, where we propose a two-layer RLnetwork to simultaneously deal with maximizing the sum rate and minimizingthe prediction loss: the first layer is for battery prediction,the second layer generates the access policy based on the output from the firstlayer.Experiment results show that the three proposed RL algorithmscan achieve better performances compared with existing benchmarks.
