摘要：
可持续物联网日益增长的需求促进了采用环境能量间歇供电的无电池设备进行感知。然而，间歇性给传感数据收集带来了重大挑战。尽管近期努力实现了单对一通信，但在多个间歇供电无电池设备之间路由数据（这是传感系统的关键需求）仍然是一个艰巨的挑战。本文通过引入Swift填补了这一空白，Swift在间歇供电无电池传感系统中实现了无缝数据路由。Swift通过三项主要创新设计克服了设备间歇性和异构能量条件带来的挑战。首先，Swift包含一个基于数论的可靠节点同步协议，确保无论能量条件如何都能成功同步。其次，Swift采用低延迟消息转发协议，允许无需重复同步即可连续转发消息。最后，Swift具有简单而有效的路由路径构建机制，使节点能够以最少跳数获得通往汇聚节点的最优路径。我们实现了Swift并进行了代表各种现实场景的大规模实验。结果表明，与最先进的间歇供电无电池传感系统方法相比，Swift在端到端消息传递时间上实现了数量级的减少。
英文摘要：
The rising demand for sustainable IoT has promoted the adoption of battery-free devices intermittently powered by ambient energy for sensing. However, the intermittency poses significant challenges in sensing data collection. Despite recent efforts to enable one-to-one communication, routing data across multiple intermittently-powered battery-free devices, a crucial requirement for a sensing system, remains a formidable challenge. This paper fills this gap by introducing Swift, which enables seamless data routing in intermittently-powered battery-free sensing systems. Swift overcomes the challenges posed by device intermittency and heterogeneous energy conditions through three major innovative designs. First, Swift incorporates a reliable node synchronization protocol backed by number theory, ensuring successful synchronization regardless of energy conditions. Second, Swift adopts a low-latency message forwarding protocol, allowing continuous message forwarding without repeated synchronization. Finally, Swift features a simple yet effective mechanism for routing path construction, enabling nodes to obtain the optimal path to the sink node with minimum hops. We implement Swift and perform large-scale experiments representing diverse realworld scenarios. The results demonstrate that Swift achieves an order of magnitude reduction in end-to-end message delivery time compared with the state-of-the-art approaches for intermittentlypowered battery-free sensing systems.
