Abstract: Energy-harvesting and wireless power transfer are quickly becoming game-changing technologies for wireless systems. The promise of self-sustained perpetual operation opens exciting possibilities for a wide range of applications from smart homes and automated highways to in-body health monitoring.
However, energy harvesting also brings a fundamental shift in communication system design principles. In conventional systems, energy is a deterministic quantity continuously available to the transmitter and transmission is constrained only in terms of
average power. In harvesting systems, energy generation can be
slow, unpredictable and fluctuate significantly over time, and communication is constrained by the energy instantaneously available to the transmitter. This necessitates new principles for power control, communication and coding. In this talk, we investigate the information and communication-theoretic foundations for this new form of communication.
Ayfer Ozgur is an Assistant Professor in the Information Systems Laboratory at Stanford University since 2012. Before joining Stanford, she was a postdoctoral researcher and a Ph.D. student at EPFL, Switzerland. She received her Ph.D. degree from EPFL in 2009 and B.Sc. and M.Sc.degrees in electrical engineering and physics from Middle East Technical University, Turkey in 2001 and 2004 respectively. From 2001 to 2004, she worked as a hardware design engineer for the Defense Industries Research and Development Institute in Turkey. She received the EPFL Best Ph.D. Thesis Award (accross all areas) in 2010 and the NSFCAREER Award in 2013. Her research interests are in wireless and network communication, information and coding theory.
