Infrastructural Support for Dynamic Context Bindings

Abstract. Research in context-aware systems shows that using context information enables the development of personalized mobile applications. The context acquisition process in a context-aware (CA) system consists of two main roles: context producing entities (e.g. wrapped sensors) and context consuming entities (e.g. CA application). A CA system can be seen as a hierarchy of associated context producers and consumers which exchange contextual information. Managing contextual information used in context aware systems, introduces additional complexity for mobile application developers. We focus on the dynamic processes of discovery, selection, (re)binding and monitoring of entities that produce context information. Dynamic context binding is complex because of the dynamic nature, in terms of availability and quality, of context producers. We propose to delegate the responsibility for context binding to the middleware infrastructure and provide application designers with a declarative la...
