摘要:

我们研究的问题,最小化的时间平均预期年龄的信息状态更新发送的能量收集源与有限容量的电池。在以前的文献中,最优策略被观察到有一个阈值结构下的泊松能量到达,一个单位容量的电池的特殊情况。在本文中,我们将这一结果推广到任何(整数)的电池容量,并明确的阈值结构的特点。我们得到的工具,以获得任意的能量缓冲区(即电池)大小的最佳策略。这些结果之一是最小平均AoI和最高能量状态的最佳阈值的意外等效性。

英文摘要:

We study the problem of minimizing the time-average expected Age of Information for status updates sent by an energy-harvesting source with a finite-capacity battery. In prior literature, optimal policies were observed to have a threshold structure under Poisson energy arrivals, for the special case of a unit-capacity battery. In this paper, we generalize this result to any (integer) battery capacity, and explicitly characterize the threshold structure. We obtain tools to derive the optimal policy for arbitrary energy buffer (i.e. battery) size. One of these results is the unexpected equivalence of the minimum average AoI and the optimal threshold for the highest energy state.
