Modeling of Context Information for Pervasive Computing Applications

Abstract

In a dynamic heterogeneous environment, such as Pervasive Computing, context-aware adaptation is a key concept to meet the varying requirements of different clients. In order to enable context-aware adaptation, context information must be gathered and eventually presented to the application performing the adaptation. Therefore, a common representation format for the context information is required. In this paper we examine possible representation formats for context information. We discuss requirements for such a representation format and how those requirements are met by existing approaches.
