能量收集传感器的时域最优传输策略

Finite-Horizon Optimal Transmission Policies for Energy Harvesting Sensors

Rahul Vaze, Krishna Jagannathan

摘要:

在本文中,我们推导出最优的传输策略,能量收集传感器,以最大限度地提高在有限的地平线上获得的效用。首先,我们考虑一个单一的能量收集传感器,离散的能量到达过程,和一个离散的能量消耗策略。在此模型下,我们证明了最优有限时间策略是一个阈值策略,并明确地刻画了阈值,阈值可以使用递归预先计算。接下来,我们解决了多个传感器的情况下,只有其中一个允许在任何给定的时间发送,以避免干扰,并推导出一个明确的最佳策略,以及这种情况下。

英文摘要:

In this paper, we derive optimal transmission policies for energy harvesting sensors to maximize the utility obtained over a finite horizon. First, we consider a single energy harvesting sensor, with discrete energy arrival process, and a discrete energy consumption policy. Under this model, we show that the optimal finite horizon policy is a threshold policy, and explicitly characterize the thresholds, and the thresholds can be precomputed using a recursion. Next, we address the case of multiple sensors, with only one of them allowed to transmit at any given time to avoid interference, and derive an explicit optimal policy for this scenario as well.
