Hibernus: Sustaining Computation During Intermittent Supply for Energy-Harvesting Systems
Domenico Balsamo,Alex S. Weddell,Geoff V. Merrett,Bashir M. Al-Hashimi,Davide Brunelli,Luca Benini +5 more
TL;DR: A new approach, Hibernus, is proposed, which enables computation to be sustained during intermittent supply by reactively hibernating: saving system state only once, when power is about to be lost, and then sleeping until the supply recovers.
Journal ArticleDOI
Internet-of-Things and big data for smarter healthcare: From device to architecture, applications and analytics
Farshad Firouzi,Amir M. Rahmani,Amir M. Rahmani,Kunal Mankodiya,Mustafa Badaroglu,Geoff V. Merrett,P. Wong,Bahar Farahani +7 more
TL;DR: The purpose of this special issue is to analyze the top concerns in IoT technologies that pertain to smart sensors for health care applications; particularly applications targeted at individualized tele-health interventions with the goal of enabling healthier ways of life.
Journal ArticleDOI
Hibernus++: A Self-Calibrating and Adaptive System for Transiently-Powered Embedded Devices
Domenico Balsamo,Alex S. Weddell,Anup Das,Alberto Rodriguez Arreola,Davide Brunelli,Bashir M. Al-Hashimi,Geoff V. Merrett,Luca Benini +7 more
TL;DR: This paper proposes Hibernus++ to intelligently adapt the hibernate and restore thresholds in response to source dynamics and system load properties, which provides an average 16% reduction in energy consumption and an improvement of 17% in application execution time over state-of-the-art approaches.
Proceedings ArticleDOI
A survey of multi-source energy harvesting systems
Alex S. Weddell,Michele Magno,Geoff V. Merrett,Davide Brunelli,Bashir M. Al-Hashimi,Luca Benini +5 more
TL;DR: This paper surveys the design of multi-source energy harvesting systems, including trade-offs affecting their efficiency, applicability, and ease of deployment, and identifies and comment upon the current and future research directions in this field.
Journal ArticleDOI
Accurate Supercapacitor Modeling for Energy Harvesting Wireless Sensor Nodes
TL;DR: It is shown that observations previously attributed to leakage are predominantly due to redistribution of charge inside the supercapacitor, and the development of a circuit-based model is confirmed, which accurately represents non-ideal behavior.
