Technical Programme

The ENSSys 2014 technical programme is shown below:

08:30 Arrival and Refreshments
09:00 Welcome to ENSsys 2014
09:15 Keynote: "Perpetual Computing"
Prabal Dutta (University of Michigan, US)
Abstract: Every decade, computers scale in size, power, and deployment density. This talk will explore some of the opportunities and challenges in scaling to the next generation and beyond. Drawing from our experiences in deploying hundreds of energy harvesting sensors, from Rubik’s Cube-size devices that draw milliamps to cubic-mm sized “Smart Dust” that draws nanoamps, and many devices in between, this talk will discuss the emerging systems architecture, and articulate some of the hardware and software challenges, of perpetual computing—of intermittently-powered systems that could conceivably last forever.
