Abstract

Sensors capable of sensing phenomena at high data rates---on the order of tens to hundreds of thousands of samples per second---are useful in many industrial, civil engineering, scientific, networking, and medical applications. In these applications, high-rate streams of data produced by sensors must be processed and analyzed using a combination of both event-stream and signal-processing operations. WaveScope is a data management and continuous query processing architecture that integrates these two different data types; ease of writing arbitrary event-stream and signal-processing functions; the ability to process several million samples per second on conventional PC hardware; and the ability to distribute application code across both PCs and sensor nodes. Our initial WaveScope implementation demonstrates high performance on several application, and targets real embedded sensor platforms. In this talk I will discuss the design of WaveScope and show one of the target platforms we have developed.

Biography

Lewis Girod received a B.S. in Mathematics and M.Eng. in Computer Science from MIT in 1995. After working at MIT/LCS for three years in the area of Internet naming infrastructure, he joined Deborah Estrin's group as a Ph.D. student in 1998. He worked full-time at Sensoria Corporation from 2000-2003 on several commercial and DARPA-funded projects, before returning to complete his Ph.D. at UCLA in 2005. Since February 2006 he is a Postdoctoral Researcher at the MIT Computer Science and Artificial Intelligence Laboratory, working with Sam Madden and Hari Balakrishnan on the WaveScope project.
