Abstract
The paper describes an agent-based web service coordination framework in ubiquitous computing. It is called context-mediated web service coordination. In the framework, all service processes in ubiquitous computing environments are wrapped in web services that have standard communication protocols. The framework coordinates sensor devices wrapped in web services, web services on the Internet, and web services that manage user profile, etc. In addition, these web services are wrapped in specific types of agents. Giving a standard agent communication protocols to the heterogeneous web service processes, the framework introduces a new agent-based service coordination layer in ubiquitous computing. Coordinating these agents based on the user’s intention and their physical contexts, we can seamlessly coordinate the heterogeneous service components over the digital and real world in a human-centered manner. We also show a prototype application of the framework, context-aware information retrieval services in a museum.
