At the Future Salon with Doug Engelbart last Friday I met fellow SDN Weblogger Pankaj Kumar for the first time. That was just great. If you are close to the SAP offices in Palo Alto tomorrow, swing by for an interesting talk. For our Bay Area SDN Members (sorry for the late notice): Please join us on Tuesday, November 23, at 1:30pm PST for an SAP Research Forum session featuring Dr. Joseph M. Hellerstein on “SensorNet Queries and Data Acquisition.” Dr. Hellerstein is a Professor of Computer Science and Director of Intel Research at the University of California, Berkeley.

UC Berkeley and Intel Research have an active and open collaboration in a number of research areas, including wireless sensor networks, planetary scale services, collaborative Internet monitoring, and technologies for emerging markets. In this talk, Dr. Hellerstein will focus on one important branch of our SensorNet agenda: query processing and data acquisition architectures for wireless sensor networks. This work has been influential in the research community, and serves as the software core for Intel’s open-source TASK sensor kit.

He will describe their work on the TinyDB system, including its features for in-network and acquisitional query processing. He will also describe more recent work on BBQ, an alternative architecture that incorporates statistical methods to improve performance and minimize power consumption, and which points to new in-network technologies for fault isolation and anomaly detection that they are currently exploring.

Dr. Hellerstein’s research focuses on data management and networking, including database systems, sensor networks, peer-to-peer and distributed systems. Before directing Intel Research Berkeley, he was a co-founder of Cohera Corporation (now part of PeopleSoft), where he served as Chief Scientist from 1998-2001. Key ideas from his research have been incorporated into commercial and open-source database systems including IBM’s DB2 and Informix, PeopleSoft’s Catalog Management, and the open-source PostgreSQL system.

He received his Ph.D. from the University of Wisconsin, a master’s degree from UC Berkeley, and a bachelor’s degree from Harvard. He spent a pre-doctoral internship at IBM Almaden Research Center, and a post-doctoral internship at the Hebrew University in Jerusalem.

Date: Tuesday, November 23, 2004 1:30pm – 3:00pm PST

Location: SAP Labs, 3410 Hillview Avenue, Palo Alto – Southern Cross Room If you are coming please say hello.
