Wireless Sensor Networks: Applications, Systems, and Security
University of Colorado Boulder
Wireless sensor networks (WSNs) have recently attracted great interest in the
computer science research community because they present a vision of computing
that is ubiquitous, networked, embedded, and wireless. In situ deployment of
widespread low cost WSNs has spurred new research in the design of sensor
operating systems, networks, security, algorithms, HCI, databases, multimedia,
etc. My WSN research can be categorized into three areas: new i) applications;
ii) systems, including network protocols as well as operating systems; and
iii) security. I will discuss our award-winning deployment of WSNs in the
Bitterroot National Forest to monitor weather conditions around active wildland
fires. I will outline our systems research on developing infrastructure to
support such applications, including our lightweight Mantis sensor OS. I will
present in depth our recent WSN research on a novel duty-cycled medium access
control protocol called X-MAC. I will conclude with a discussion of our
wireless security research for WSNs, focusing on our first-of-a-kind INSENS
intrusion-tolerant routing protocol and our traffic analysis research.
Richard Han joined the Department of Computer
Science at the University of Colorado Boulder in August 2001 as an
Assistant Professor and leads the
MANTIS
wireless sensor networking project at CU-Boulder.
He received a National Science Foundation CAREER Award in 2002, IBM Faculty
Awards in 2002 and 2003, and a Best Paper Award at ACM MobiSys 2006.
Han was a Research Staff Member at IBM's Thomas J. Watson Research Center in
Hawthorne, New York from 1997-2001. Han received a PhD in Electrical
Engineering from the University of California at Berkeley in 1997 and a BS
in Electrical Engineering, with distinction, from Stanford University in 1989.
