Seamless Mobility on Ubiquitous Hardware
Prof. Mahadev Satyanarayanan, Carnegie Mellon University
Abstract:
In this talk, I will describe Internet Suspend/Resume (ISR),
a pervasive computing technology that rapidly personalizes
and depersonalizes anonymous hardware for transient use. As
its name implies, ISR mimics the closing and opening of a
laptop. A user can suspend work on an ISR machine at one
location, travel to another location, and resume work there
on any other ISR machine. Hardware virtualization and file
caching are the keys to ISR's precise customization and
simple administration.
Satyanarayanan is the Carnegie Group Professor of Computer Science at
Carnegie Mellon University. From May 2001 to May 2004, he served as the
founding director of Intel Research Pittsburgh, which focuses on
software systems for distributed data storage. In this role, he was a
co-inventor of the Internet Suspend/Resume approach to pervasive
computing, as well as the Diamond approach to interactive search of
complex, non-indexed data. He is the founding Editor-in-Chief of IEEE
Pervasive Computing. He received the PhD in Computer Science from
Carnegie Mellon, after Bachelor's and Master's degrees from the Indian
Institute of Technology, Madras. He is a Fellow of the ACM and the IEEE.
The term "mobile computing" typically evokes images of a
laptop, handheld, or wearable computer. However, the
plummeting cost of hardware suggests that pervasive
computing infrastructure could minimize the need to carry
such devices in the near future. In such a world, personal
computing will be available anywhere on demand, like light
at the flip of a switch. Only when a user starts to use a
computer will it acquire his unique customization and
state. When he finishes using the computer, this
customization and state will disappear from it. Thus, a user
could travel hands-free yet be confident of making
productive use of slivers of free time anywhere
Biography:
Professor Satyanarayanan is one of the founders of the field of mobile
information access. One outcome of his work is the Coda File System
which supports disconnected and bandwidth-adaptive operation. Key ideas
from Coda have been incorporated by Microsoft into the IntelliMirror
component of Windows 2000. The Cached Exchange Mode of Microsoft Outlook
2003 builds directly on Coda's caching approach to disconnected and
weakly connected operation. Another outcome of Satyanarayanan's research
is Odyssey, a set of open-source operating system extensions for
enabling mobile applications to adapt to variation in critical resources
such as bandwidth and energy. Coda and Odyssey are building blocks in
Project Aura, a research initiative at Carnegie Mellon to build a
distraction-free ubiquitous computing environment. Earlier,
Satyanarayanan was a principal architect and implementor of the Andrew
File System (AFS) which was commercialized by IBM.
