An approach to domain-based scalable context management architecture in pervasive environments.

  In pervasive environments, context management
systems are expected to administrate large volume of
contextual information that is captured from spatial to
nonspatial elements. Research in context-aware computing
produced a number of middleware systems for context
management to intermediate the communications between
applications and context providers. In particular, in pervasive
environments, the design of distributed storage,
retrieval and propagation mechanisms of context information
across domains is vital. In this paper, we propose a
domain-based approach to address the requirements of
scalable distributed context management, cross-domain
efficient context information dissemination and domainbased
privacy policy enforcement. We propose infinitum, a
middleware architecture that incorporates the management
and communication benefits of the Google Wave Federation
Protocol, while also taking advantage of the semantic
and inference benefits of ontology-based context models.
This architecture establishes a robust cross-domain scalable
context management and collaboration framework,
which has been implemented and evaluated in a real-life
application of ‘‘SMART University’’ to support virtual team collaboration.
