摘要

无电池传感设备从周围环境中获取能量,以执行传感、计算和通信。这些设备面临的一个核心挑战是在不稳定、随机或不规则的能源可用性下保持可用性,这会导致执行不一致、服务丢失和电源故障。基于可用或预测的功率/能量调整执行(降级或升级)似乎有望避免电源故障、满足最后期限或提高吞吐量。然而,由于有限的资源和有限的本地信息,决定什么和何时适应是具有挑战性的。本文探讨了间歇性供电计算机的能量感知自适应的基本原理,并提出了启发式自适应机制,在运行时动态调节程序复杂性,以实现更高的传感器覆盖和吞吐量。虽然我们的目标是无电池、间歇性供电、资源受限的传感器,但我们看到了所有能量收集设备的普遍应用。

Heuristic Adaptation for Intermittently Powered Batteryless Sensors
Battery-free sensing devices harvest energy from their surrounding environment to perform sensing, computation, and communication. A core challenge for these devices is maintaining usefulness despite erratic, random, or irregular energy availability, which causes inconsistent execution, loss of service, and power failures. Adapting execution (degrading or upgrading) based on available or predicted power/energy seems promising to stave off power failures, meet deadlines, or increase throughput. However, due to constrained resources and limited local information, deciding what and when exactly to adapt is challenging. This article explores the fundamentals of energy-aware adaptation for intermittently powered computers and proposes heuristic adaptation mechanisms to dynamically modulate the program complexity at run-time to enable higher sensor coverage and throughput. While we target battery-free, intermittently powered, resource-constrained sensors, we see a general application to all energy harvesting devices.
