Energy-synchronized computing for sustainable sensor networks
چکیده انگلیسی

To ensure sustainable operations of wireless sensor systems, environmental energy harvesting has been regarded as one of the most fundamental solutions for long-term applications. In energy-dynamic environments, energy conservation is no longer considered necessarily beneficial, because energy storage units (e.g., batteries or capacitors) are limited in capacity and leakage-prone. In contrast to legacy energy conservation approaches, we aim at energy-synchronized computing for wireless sensor devices. The starting point of this work is TwinStar, which uses ultra-capacitor as the only energy storage unit. To efficiently use the harvested energy, we design and implement leakage-aware feedback control techniques to match the activities of sensor nodes with dynamic energy supply from environments. We conduct system evaluation under both indoor and outdoor typical real-world settings. Results indicate our leakage-aware energy-synchronized control can effectively utilize energy that could otherwise leak away.
