We introduce ScAlg, a decentralized algorithm that leverages wake-up radios to scatter the active times of battery-free devices in a network, ensuring continuous operation and enhanced dependability even with tight energy constraints. Our approach leverages intermittent computing principles to reduce redundant activities and improve energy efficiency. By conducting simulations and hardware experiments, we demonstrate the algorithm’s effectiveness. Although this is a work in progress, our findings show potential for strategic alignment of active times and intelligent task management in achieving sustainable, batteryless IoT systems capable of maintaining functionality in energy-variable environments.enBattery-free sensor networksDistributed sensingEmbedded systemsEnergy harvestingWake-up radiosComputer Science, Information and General Works::004: Computer SciencesConference PaperConference Paper
