How to design smart sensors with environmental energy and real-time capabilities

A growing number of applications (e.g. medical, automotive) involve many wireless devices that may be deployed in wide areas and possibly unattainable places. Such systems should be designed to function perpetually without any human intervention because either costly or impractical. As a consequence, energy harvesting technology has been an area of rapid development during the last decade. Energy harvesting is a technology that allows to capture unused ambient energy. It is converted into electrical energy which is used immediately or later through a storage unit for powering these devices which in addition to energy limitations have to cope with real-time constraints. Consequently, energy harvesting sensors need to be provided with specific real-time scheduling and power management facilities. This keynote addresses state of the art as well as our findings in real-time scheduling and processor activity management for energy harvesting small electronic devices such as autonomous sensors.

Short Bio

Maryline Chetto is currently a full professor in computer engineering with the Institute of Technology of the University of Nantes, France.

She received the degree of Docteur de 3ème cycle in control engineering and the degree of Habilitée à Diriger des Recherches in Computer Science from the University of Nantes, France, in 1984 and 1993, respectively. From 1984 to 1985, she held the position of Assistant professor of Computer Science at the University of Rennes, while her research was with the Institut de Recherche en Informatique et Systèmes Aléatoires (IRISA), Rennes. In 1986, she returned to Nantes and has been from 2002 a full professor with the University of Nantes.

She is conducting her research at Laboratoire des Sciences du Numérique de Nantes (LS2N) in the Real Time System team. Her main research interests include Scheduling, Fault-tolerance and Dynamic Power Management technologies for real time embedded applications. She is now studying the issue of scheduling tasks under real-time constraints in a device such as sensor node that uses renewable energy to supply it.

She has more than 150 papers published in international journals and conferences. She was the editor of the books Real-time Systems Scheduling (Elsevier, 2014) with volume 1 Fundamentals and Volume 2 Focusses. She was the co-author of the book Energy Autonomy of real-time systems (Elsevier, 2016). She was the Chairman of the French national Project Cleopatre ” Composants Logiciels sur Etagères Ouverts Pour les Applications Temps-Réel Embarquées” (2002-2005). She was the program committee co-chair of the 17th International Conference on Real-Time and Network Systems (2009). Since 2011, she was elected member of the French National Council for Universities.
