Towards a peer-to-peer middleware for context provisioning in spontaneous networks
Résumé
Context-awareness has been widely considered important for applications to provide adaptable services to changes in dynamic environments. Classical approaches have mainly focused on gathering and representing internal contextual information from integrated sensors. Recent work has shown that useful external contexts can also be acquired from the surrounding environment in a distributed manner. However, the dynamism and heterogeneity of spontaneous networks raise new challenges for the provisioning of such information. This paper describes our ongoing work on a peer-to-peer middleware for abstracting contexts as logical peers in independent overlay networks. Context data retrieval then becomes transparent to applications and other middleware services. The proposed middleware will support efficient construction and maintenance of these overlays and offer common interfaces to applications. We discuss in detail its architecture and the open issues to be resolved
