Taming the Dynamics of Distributed Data
Prof. Krithi Ramamritham, IIT Bombay
Date & Time: January 31, 2003 16:00
Venue: CSE Seminar Room
Abstract:
Data gathered from (wireless sensor) networks and those delivered today via the web reflect rapid and unpredictable changes in the world around us. Clearly, the Quality of Service needs for such delivery are much more stringent than for static data. This talk will examine the nature of dynamics of distributed data, study the suitability of the current infrastructure for disseminating time varying information, and discuss fresh approaches tailored for querying dynamic data. We will demonstrate that executing user queries over dynamic data at the edge of the network, e.g., at Data Aggegators, will improve scalability and reduce overheads but poses challenges in terms of delivering consistent query results. How these challenges can be met by the judicious design of algorithms for data dissemination, caching, replication, transcoding, and cooperation, forms the crux of the talk.
