Colloquium - Han

Wireless sensor networks are rapidly emerging as an important new research area. This talk will introduce the field of wireless sensor networks, and discuss the research challenges associated with sensor networks. To address these challenges, my research group has formed Project MANTIS, which is focused on building system support for MultimodAl NeTworks of In-situ Sensors. This talk will describe the lightweight new sensor operating system that we have built called MANTIS OS, as well as our new hardware sensor platform called the MANTIS Nymph. I will discuss our novel use of the MANTIS system to create sensor-enabled user interfaces in a smart space, namely the BP Center's immersive visualization environment. A key focus of our research has been on enabling security support for sensor networks. This talk will discuss the research challenges associated with securing sensor networks, and I will describe INSENS, our innovative INtrusion-tolerant routing protocol for SEnsor NetworkS - the first comprehensive secure routing system for WSNs.

Rick Han joined the faculty of the Department of Computer Science at the University of Colorado Boulder in August 2001 as an Assistant Professor. He received a National Science Foundation CAREER Award in 2002 and an IBM Faculty Partnership Award in 2002. His research interests include system support for wireless sensor networks, secure wireless networks, ubiquitous computing, and context-aware smart spaces. Prior to joining CU-Boulder, Prof. Han was a Research Staff Member for four years at IBM's Thomas J. Watson Research Center in Hawthorne, NY. Prof. Han received his PhD in Electrical Engineering from the University of California at Berkeley in 1997.
