Supporting Adaptive Ubiquitous Applications With the Solar System

Abstract

As we embed more computers into our daily environment, ubiquitous computing promises to make them less noticeable and help to prevent information over-load. We see, however, few ubiquitous applications that are able to adapt to the dynamics of user, physical, and computational context. We believe that there are two challenges causing this lack of ubiquitous applications: there is no exible and scalable way to support information collection and dissemination in a ubiquitous and mobile environment, and there is no general approach to building adaptive applications given heterogeneous contextual information. We propose a system infrastructure, Solar, to meet these challenges. Solar uses a subscription-based operator graph abstraction and allows dynamic composition of stackable operators to manage ubiquitous information sources. After developing a set of diverse adaptive applications, we expect to identify fundamental techniques for context-aware adaptation. Our expectation is that Solar's end-to-end support for information collection, dissemination, and utilization will make it easy to build adaptive applications for a ubiquitous mobile environment with many users and devices.
