无电池节点的协作对于成功取代传统的基于电池的系统至关重要。能量收集传感器节点会经历能源可用性的时空波动。当传感器节点没有足够的能量存储来补偿这些波动时，这些波动变得尤其严重。了解无电池传感器节点运行组的挑战和机遇需要记录和再现真实能源环境的时空特征。因此，我们推出了 Shepherd，这是一个无电池物联网的测试平台。 Shepherd 允许以 100 kHz 的速率记录分辨率为 3 μA 和 50μV 的同步能量迹线，并将这些迹线忠实地重播到任意数量的传感器节点以研究它们的行为。我们将 Shepherd 作为社区的开源工具发布，促进对无电池系统的时间同步、无线网络和其他分布式算法的研究。
Collaboration of batteryless nodes is essential to their success in replacing traditional battery-based systems. Energy-harvesting sensor nodes experience spatio-temporal fluctuations of energy availability. These fluctuations become especially critical when sensor nodes do not have sufficient energy storage to compensate for them. Understanding the challenges and opportunities of operating groups of batteryless sensor nodes requires to record and reproduce spatio-temporal characteristics of real energy environments. We thus present Shepherd, a testbed for the batteryless IoT. Shepherd allows to record synchronized energy traces with a resolution of 3 μA and 50μV at a rate of 100 kHz, and to faithfully replay these traces to any number of sensor nodes to study their behavior. We release Shepherd as an open-source tool for the community, facilitating research into time synchronization, wireless networking, and other distributed algorithms for batteryless systems.
