摘要：
物联网的蓬勃发展彻底改变了人们的生活，但也导致了大量的资源消耗和环境污染。近年来，绿色物联网（GIoT）已成为解决这一问题的全球共识。在本文中，我们提出了EEWScatter，一种节能的WiFi反向散射通信系统，以实现GIoT的目标。与以往仅关注标签的反向散射系统不同，我们的方法提供了系统级的全面节能视角。具体而言，我们重用环境信号作为载波，并利用超低功耗、无电池的设计来实现标签节点的反向散射。此外，我们设计了一种新的基于CRC的算法，使得仅使用单个接收器即可解调环境数据和标签数据，同时利用环境载波。这种设计消除了系统对高功耗冗余收发器的依赖。结果表明，EEWScatter实现了最低的整体系统功耗，并节省了至少一半的能量。更重要的是，我们标签的功耗仅为有源无线电的1/1000。我们相信EEWScatter是迈向可持续未来的关键一步。
英文摘要：
The boom of the Internet of Things has revolutionized people's lives, but it has also resulted in massive resource consumption and environmental pollution. Recently, Green IoT (GIoT) has become a worldwide consensus to address this issue. In this paper, we propose EEWScatter, an energy-efficient WiFi backscatter communication system to pursue the goal of GIoT. Unlike previous backscatter systems that solely focus on tags, our approach offers a comprehensive system-wide view on energy conservation. Specifically, we reuse ambient signals as carriers and utilize an ultra-low-power and battery-free design for tag nodes by backscatter. Further, we design a new CRC-based algorithm that enables the demodulation of both ambient and tag data by only a single receiver while using ambient carriers. Such a design eliminates system reliance on redundant transceivers with high power consumption. Results demonstrate that EEWScatter achieves the lowest overall system power consumption and saves at least half of the energy. What's more, the power consumption of our tag is only 1/1000 of that of active radio. We believe that EEWScatter is a critical step towards a sustainable future.
