CoastalNet: Underwater Sensor Networks for Ecological Research
Asst.Prof. Volkan Rodoplu
Abstract:
We address the development of underwater sensor network systems for ecological research. Despite the substantial NSF-funded effort to monitor aquatic ecological systems, the infrastructure needed for underwater data collection is primitive at best and lags far behind that available for its terrestrial counterparts. We describe an integrated research program (CoastalNet) that comprises networking, physical layer and hardware platform solutions for data collection at relevant spatial and temporal scales. In this talk, we focus on the networking aspects of this program. The bits-per-Joule capacity is proposed as a novel metric to measure the performance of delay-tolerant data such as conductivity, temperature and depth (CTD) measurements. The fact that the bits-per-Joule capacity of underwater sensor networks scales up in the number of sensors motivates the large-scale coastal deployment of an underwater sensor network. We describe novel data link layer, multiple access, and topology control protocols that are energy-efficient, distributed, localized and scalable. Further, they are designed to work despite the long propagation delays of the underwater acoustic medium. We conclude by describing the broader impacts of this work for the Long-term Ecological Research (LTER) sites around the world.
A short biography:
Volkan Rodoplu graduated from Robert College in 1992, received his B.S. degree in Electrical Engineering from Princeton University in 1996, and his M.S. degree in Electrical Engineering from Stanford University in 1998. He worked for Texas Instruments (Dallas, TX) in the summer of 1998, on multiuser detection and interference cancellation algorithms, and for Tensilica, Inc. (Santa Clara, CA) during 2000-2001 on turbo decoding algorithms and architectures for reconfigurable processors. He received his Ph.D. in Electrical Engineering from Stanford University in 2003 and joined the Department of Electrical and Computer Engineering at UCSB as an Assistant Professor. He is the recipient of the George B. Wood Legacy Prize, John W. Tukey Award, G. David Forney Jr. Prize and a Stanford Electrical Engineering Outstanding Service Award.
