摘要

Mobile devices are evolving into hubs of content and context information. Many research projects have shown the potential for new pervasive computing applications. This article shows how Web and resource-based smart spaces can support pervasive applications in a wide variety of devices. A framework that employs a resource-based HTTP style for pervasive services called Representational State Transfer (REST) can enable easy mashup of applications. This framework has several important features. First, a flexible access control mechanism on top of the OpenID and OAuth protocols provides security and access control in heterogeneous, dynamic environments. Second, a search engine can collaborate with existing service and network discovery mechanisms to find resources on the basis of their indoor location. Finally, an emerging W3C standard, Delivery Context: Client Interfaces (DCCI), facilitates sharing information within a device in an interoperable fashion.
