M.S. Paper Title: SEASONS: Signal and Energy Aware Sensing on iNtermittent Systems
Abstract: Both energy-aware, batteryless intermittent systems and signal-aware adaptive sampling algorithms (ASA) aim to minimize sensor data accuracy under energy constraints in edge devices. Intuitively, combining both into a signal- & energy-aware solution would yield even better accuracy. Unfortunately, ASAs and intermittent systems rely on conflicting energy availability assumptions. So, a straightforward combination cannot achieve their combined benefits. Therefore, we propose SEASONS, the first framework for signal- and energy-aware intermittent systems. SEASONS buffers signal data in time, monitoring queue dynamics to ensure the data is reported within a user-specified latency constraint. SEASONS improves sensor data accuracy by 31% without increasing energy usage.
