Abstract

Ubiquitous computing is more complex and dynamic than distributed computing and mobile computing because of its pervasiveness. This paper presents a context infrastructure to provide the semantic interoperability of context in a ubiquitous computing environment. In addition, we explore the web services approach to support interaction interoperability between the components of the context infrastructure on heterogeneous platforms. First, we develop context ontology- Entity, contextType, and Value - for providing semantic interoperability of context. Then, we suggest a context infrastructure using the web services for interaction interoperability. We also explain context reasoning and evaluate the performance of the context infrastructure.
