A policy based framework for context aware ubiquitous services

Abstract

This paper introduces the idea of using a policy mechanism to control context aware behaviour for ubiquitous and mobile services. The paper also discusses the usefulness, design architecture and prototype implementation of the Mobile Hanging Services framework that supports proactive and ad hoc awareness services in ubiquitous environments. An approach for contextual services that uses policies (a set of rules) to govern the service execution is illustrated through a sample Windows Media Player application. © Springer-Verlag Berlin Heidelberg 2004.
