Distinguished Lecture: The Vision and Reality of Ubiquitous Computing

Wednesday, January 9, 2008 - 3:02pm

HENNING SCHULZRINNE, Columbia University

TIME: 3:30 – 4:30 p.m.
PLACE: Engineering Science Building, Room 1001


About ten years ago, the notion of ubiquitous computing first appeared, just as the first truly mobile devices became available. Ten years later, the notion of ubiquitous computing as integrating computing into the environment has not quite panned out, with the emphasis shifting to personal, mobile devices. In this talk, I will try to illustrate some of the user-focused challenges that derive from the goals of ubiquitous computing. We have also started to address some aspects of the problem with our work on service and session mobility, as well as attempts to offer core network services, such as email and web access, in partially disconnected environments.


Prof. Henning Schulzrinne received his Ph.D. from the University of Massachusetts in Amherst, Massachusetts. He was a member of technical staff at AT&T Bell Laboratories, Murray Hill and an associate department head at GMD-Fokus (Berlin) before joining the Computer Science and Electrical Engineering departments at Columbia University, New York. He is currently chair of the Department of Computer Science.

Protocols co-developed by him, such as RTP, RTSP and SIP, are now Internet standards, used by almost all Internet telephony and multimedia applications. His research interests include Internet multimedia systems, ubiquitous computing, mobile systems, quality of service, and performance evaluation. He is a Fellow of the IEEE.D
