Title: Collaborative Adaptive Sensing of the Atmosphere: Challenges in End-to-End Sensor Networking

Abstract: The CASA project is an NSF Engineering Research Center investigating the design and implementation of a dense network of low-power meteorological radars whose goal is to collaboratively and adaptively sense the lowest few kilometers of the earth's atmosphere. In the first part of this talk we overview the CASA project, describe its computing and networking challenges, and overview the software/network architecture and implementation of the CASA testbeds. We also discuss the operation of CASA’s testbed during spring tornado season in Oklahoma. In the second part of this talk, we focus on networking-related research issues and discuss our experiences in using user-specified preferences to drive the optimization of the network's sensing behavior. Throughout the talk, we’ll discussion of a number of on-going and open research issues.

Bio: Jim Kurose received a B.A. degree in physics from Wesleyan University and his Ph.D. degree in computer science from Columbia University. He is currently Executive Associate Dean of the College of Natural Sciences and Distinguished University Professor (and past chairman) in the Department of Computer Science at the University of Massachusetts. Professor Kurose has been a Visiting Scientist at IBM Research, INRIA, Institut EURECOM , the University of Paris, LIP6, and Thomson Research Labs.

His research interests include network protocols and architecture, network measurement, sensor networks, multimedia communication, and modeling and performance evaluation. Dr. Kurose has served as Editor-in-Chief of the IEEE Transactions on Communications and was the founding Editor-in-Chief of the IEEE/ACM Transactions on Networking. He has been active in the program committees for IEEE Infocom, ACM SIGCOMM, and ACM SIGMETRICS conferences for a number of years, and has served as Technical Program Co Chair for these conferences. He has received several conference best paper awards, the ACM Sigcomm Test of Time Award, and a number of teaching awards including the IEEE Taylor Booth Education Medal. He has been active in a number of statewide computing and educational initiatives. He is a Fellow of the IEEE and the ACM. With Keith Ross, he is the co-author of the textbook, Computer Networking, a top down approach (5th edition) published by Addison-Wesley Longman.
