摘要翻译：
我们考虑一个能量收集源，它在通信会话时间内从物理现象中收集测量值并将更新发送到目的地。更新会导致传输延迟，这是传输中使用的能量的函数。每次更新使用的传输能量越多，到达目的地的速度就越快。目标是以及时的方式发送更新，即，在能量因果关系约束的情况下，使得信息的总时间在通信会话结束时最小化。我们考虑这个问题的两个变体。在第一个设置中，源控制测量更新的数量、它们的传输时间和在它们的传输中使用的能量量（这控制它们所引起的延迟或服务时间）。在第二种设置中，测量更新随着时间的推移而从外部到达，因此更新的数量变得固定，代价是为问题添加数据因果关系约束。我们在这两种情况下刻画了年龄最小策略，并讨论了信息年龄度量与能量收集文献中使用的其他度量的关系。

英文摘要：
  We consider an energy harvesting source that is collecting measurements from a physical phenomenon and sending updates to a destination within a communication session time. Updates incur transmission delays that are function of the energy used in their transmission. The more transmission energy used per update, the faster it reaches the destination. The goal is to transmit updates in a timely manner, namely, such that the total age of information is minimized by the end of the communication session, subject to energy causality constraints. We consider two variations of this problem. In the first setting, the source controls the number of measurement updates, their transmission times, and the amounts of energy used in their transmission (which govern their delays, or service times, incurred). In the second setting, measurement updates externally arrive over time, and therefore the number of updates becomes fixed, at the expense of adding data causality constraints to the problem. We characterize age-minimal policies in the two settings, and discuss the relationship of the age of information metric to other metrics used in the energy harvesting literature.
