Abstract

Building on the success of early wireless sensor network deployments, researchers are planning increasingly ambitious projects involving large numbers of widely distributed sensors and associated infrastructure. To this end, significant research attention has been focused on the scaling of the underlying algorithms and protocols for wireless sensor networks, but less attention has been placed on the architectural considerations of such systems. In this talk, I argue that large sensor network deployments require a rethinking of fundamental sensornet service abstractions because they represent large infrastructure investments that must be shared by many user communities and applications. Drawing on our experience in the HiFi project of providing data cleaning for wireless sensors networks and RFID-based systems, I examine the need for more flexible architectures that address the conflicting goals of protecting applications from complexity while allowing functionality to be adjusted on a per-application basis. This talk will outline this problem with specific examples from our work on sensor data management and will discuss some initial solutions.

Biography of Speaker

Michael Franklin is a Professor of Computer Science at the University of California, Berkeley and is a Co-Founder and CTO of Amalgamated Insight, Inc., a technology start up in Foster City, CA. At Berkeley his research focuses on the architecture and performance of distributed data management and information systems. His recent projects cover the areas of wireless sensor networks, XML message brokers, data stream processing, scientific grid computing, and data management for the digital home. He spent several years as a database systems developer in industry prior to receiving his PhD from the University of Wisconsin, Madison in 1993. He was program committee chair of the 2005 ICDE conference and 2002 ACM SIGMOD conference, and is on the editorial board of the ACM Transactions on Database Systems and the VLDB Journal. He is a Fellow of the Association for Computing Machinery, a recipient of the National Science Foundation Career Award, and the ACM SIGMOD "Test of Time" award.
