Materializing ubiquitous computing environments

Abstract

A key challenge in ubiquitous computing is how to manage ambient information about the real-world environment where a variety of devices appear and disappear. Traditional capability description systems are inadequate in capturing dynamic changes in the environment. We propose the Toibox DVMS system, a multi-embedded database system that provides an integrated database view of computing devices. The integrated views are materialized; updates over the view provoke relevant operations for the specified devices. The materialized views are decentralized and incrementally maintained by data dissemination. This work presents the design of the Toibox system, based on our initial prototype implementations.
