| Abstract: | : | Various industry forecasts project that, by 2020, there will be
around 50 billion devices connected to the Internet of Things (IoT), helping to
engineer new solutions to societal-scale problems such as healthcare, energy
conservation, transportation, etc. Most of these devices will be wireless due
to the expense, inconvenience, or in some cases, the sheer infeasibility of
wiring them. Further, many of them will have stringent size constraints. With
no cord for power and limited space for a battery, powering these devices (to
achieve several months to possibly years of unattended operation) becomes a
daunting challenge. This talk will highlight some promising directions for
addressing this challenge, focusing on the design of ultra-low power hardware
platforms that integrate computing, sensing, storage, and wireless connectivity
in a tiny form factor, the development of intelligent system-level power
management techniques, and the use of environmental energy harvesting to make
IoT devices self-powered, thus decreasing – in some cases, even eliminating –
their dependence on batteries. We will illustrate case-studies of systems that
use the above techniques judiciously, including the QUBE wireless embedded
platform, which exploits the characteristics of emerging non-volatile memory
technologies to seamlessly and efficiently enable long-running computations in
systems that experience frequent power loss (i.e., intermittently powered
systems). Biography: Vijay Raghunathan is an Associate Professor in the School of Electrical and Computer Engineering at Purdue University, where he leads the Embedded Systems Lab. His research interests include hardware and software architectures for embedded systems, wireless sensors for the Internet of Things (IoT), and wearable and implantable electronics, with an emphasis on ultra-low power design, micro-scale energy harvesting, emerging memory technologies, and reliable/secure system design. Vijay has co-authored numerous book chapters, journal and conference papers, and has presented several invited talks and tutorials on the above topics. He is a recipient of the NSF CAREER award (2010) and the Edward K. Rice Outstanding Doctoral Student Award from the UCLA School of Engineering and Applied Sciences (2005). He received best paper awards at the ACM/IEEE International Conference on VLSI Design (VLSID) in 2016 and the ACM International Conference on Embedded Networked Sensor Systems (SenSys) in 2011, the design contest award at the ACM/IEEE International Symposium on Low Power Electronics and Design (ISLPED) in 2014 and 2005, the best student paper award at the IEEE International Conference on VLSI Design (VLSID) in 2000, and a best paper award nomination at the ACM/IEEE International Symposium on Low Power Electronics and Design (ISLPED) in 2006. Vijay has served on the organizing and technical program committees of several leading ACM and IEEE conferences. He has served as Technical Program Co-chair for the ACM/IEEE International Symposium on Low Power Electronics and Design (ISLPED), and the ACM/IEEE International Conference on Information Processing in Sensor Networks (IPSN). He is currently an Associate Editor of the ACM Transactions on Embedded Computing Systems (TECS) and the ACM Transactions on Sensor Networks (TOSN). Vijay received the B.Tech. degree in Electrical Engineering from the Indian Institute of Technology, Madras and the M.S. and Ph.D. degrees in Electrical Engineering from the University of California, Los Angeles. |
