Data Management in Sensor Networks

Samuel Madden

Abstract: This tutorial will cover recent topics in data management for sensor networks, focusing in particular on high-level systems and languages for querying stored and streaming data in such networks. We will begin with a survey of language proposals, including TinyDB, Cougar, Regions, and other more recent work, and will then examine a range of implementation issues that arise in such systems, including issues related to power efficiency, time synchronization, data collection and dissemination, fault-tolerance, and state management. After attending the tutorial, audience members should have a good understanding of the various systems in this space as well as an awareness of the technical issues that make building such systems difficult.
