Abstract:
Handheld devices such as mobile phones and PDAs have evolved
into multi-functional platforms with significant computational, storage
and networking capabilities. Device manufacturers are also embedding
tiny sensors into these devices for environmental and personal health
monitoring. The natural question in this context is how to share the
data stored on these devices. In delay tolerant applications, query
propagation and information access is via opportunistic exchange of
information amongst mobile devices in proximity of one another. In this
talk, we will explore the design space of delay tolerant applications.
Understanding user interactions is essential to designing efficient
algorithms and enhancing user experience. We will describe experiments
carried out on campus to glean human contact patterns and the lessons
learned. To effect information exchange, mobile devices need to become
aware of other devices in their environment. This device discovery
process is energy intensive and motivates the need for energy efficient
contact probing mechanisms. We will discuss recent results on the
design of algorithms which offer a favorable trade-off between energy
and performance.

Motani is an Assistant
Professor in Electrical and Computer Engineering at the National
University of Singapore. He graduated with a PhD from Cornell
University. Prior to that, he was a member of technical staff
at Lockheed Martin in Syracuse, New York for over four years. Recently
he has been working on research problems which sit at the boundary of
information theory, communications and networking, including the design
of wireless ad-hoc and sensor network systems. He was awarded the Intel
Foundation Fellowship for work related to his PhD in 2000, won the
Telecom Italia prize at Simagine 2003 and advanced to the Semifinals at
Startup@Singapore 2005. He has been on the organizing
committees for ISIT 2006 & 2007 and the technical program
committees of MobiCom 2007, Infocom 2008, SECON 2008 and other
conferences. He participates actively in IEEE & ACM/Sigmobile
and has served as the secretary of the IEEE Information Theory Society
Board of Governors. |
