Elif Tuğçe Ceran, Deniz Gündüz, András György

摘要:

时间平均预期年龄的信息(AoI)的研究从能量收集发射机发送的状态更新与有限容量的电池。在信道和能量收集统计信息已知的情况下,研究了不同反馈机制下的最优调度策略。对于未知环境的情况,提出了一种平均成本强化学习算法,实时学习系统参数和状态更新策略。数值结果验证了所提方法的有效性。

英文摘要:

The time average expected age of information (AoI) is studied for status updates sent from an energy-harvesting transmitter with a finite-capacity battery. The optimal scheduling policy is first studied under different feedback mechanisms when the channel and energy harvesting statistics are known. For the case of unknown environments, an average-cost reinforcement learning algorithm is proposed that learns the system parameters and the status update policy in real time. The effectiveness of the proposed methods is verified through numerical results.
