Title: Experiences Building In Situ Wireless Sensor Networks and Location-Aware Mobile Social Networks

Abstract
Wireless sensor networks (WSNs) have attracted strong interest in the computer science research community because powerful new applications can be built by utilizing potentially millions of small networked wireless computing devices. This talk will describe the systems research and practical experiences gained by Prof. Han's research group during several small-scale experimental deployments of WSNs, including FireWxNet, a WSN to monitor wildland forest fires in the mountains of Idaho, and SensorFlock, an airborne WSN of micro-air vehicles to monitor toxic plumes. Ongoing WSN research by Prof. Han's group will be described, including a delay-tolerant WSN to aid biologists in studying disease propagation among mule deer in the Colorado Rocky Mountains by measuring wildlife contact rates. In addition, Prof. Han will describe his group's recent experimental research towards establishing a new direction in mobile computing, namely location-aware mobile social networks. This exciting direction has been stimulated by the tremendous popularity of smartphones like the iPhone and by the explosive growth of online social networks like Facebook.

Bio
Richard Han is an associate professor in the Department of Computer Science at the University of Colorado at Boulder. Prof. Han's research interests span mobile computing systems and applications, mobile social networks, wireless sensor networks (WSNs), embedded operating systems, and wireless security and privacy. Prof. Han is an NSF CAREER Award winner, an IBM Faculty award winner, and a Best Paper award winner at ACM MobiSys 2006 for FireWxNet, a WSN deployed in the Bitterroot National Forest of Idaho to collect weather data surrounding wildland forest fires. His research group focuses on developing experimental wireless systems and applications, and has published work on the WhozThat location-aware mobile social network, the open source Mantis sensor operating system, here, the short preamble duty-cycled X-MAC protocol for WSNs, and the SensorFlock airborne WSN, as well as papers on secure routing and secure code distribution for WSNs.

He is an associate editor of IEEE Transactions on Mobile Computing, has served on the Technical Program Committees of ACM MobiSys and ACM SenSys, and was general co-chair for ACM MobiSys 2008. He graduated from Stanford University in 1989 with a B.S. in Electrical Engineering with distinction, and graduated from the University of California at Berkeley in 1997 with a Ph.D in Electrical Engineering. While on his sabbatical in AY 2008-2009, he co-founded a startup company TechoShark, Inc. in location-aware mobile social networks.
