Battery-free Internet of Things has emerged as a new paradigm for the Internet of Things (IoT) that promotes sustainability. Unlike traditional wireless sensor networks, which are powered by batteries or use energy harvesting to charge onboard batteries, battery-free IoT relies solely on energy harvested from the environment, which is stored in a small capacitor. Due to unreliable ambient energy, battery-free IoT devices cannot operate continuously and often face intermittent functionality. This intermittent operation presents significant challenges for fundamental IoT tasks related to both computing and communication. While the computing aspects of battery-free IoT have been extensively studied recently, communication among battery-free IoT devices remains a pressing challenge. This chapter introduces the IoT background, discusses the computing and communication challenges associated with battery-free IoT, summarizes our research questions on communication in this thesis, and highlights our contributions to the field.
