Energy-aligned wake-up scattering for batteryless devices

Batteryless systems promise a revolution in the Internet of Things (IoT) by eliminating the need for batteries, thereby reducing maintenance costs and environmental impact. However, these systems face significant challenges in energy management, which become even more complex when devices are required to collaborate with one another. In this demo, we showcase ScAlg, a decentralized algorithm that leverages wake-up receivers to scatter wake-up times within a fully connected network of batteryless devices. This approach improves operational continuity and reliability under strict energy constraints. Our hardware setup demonstrates how batteryless nodes utilize wakeup receivers to coordinate their wake-up schedules based on energy availability dynamically, enabling sustained operation and collision-free communication.
