A Context-Aware Content-Provision Service Based on a Ubiquitous Service-Oriented Network Framework

Abstract

As emerging technologies are being developed, a ubiquitous computing environment will be established in the near future. Researches on service provisions for users over the ubiquitous computing environment have been started. The implementation method of an actual service, based on our proposed service-provision framework, is described in this paper. The service is a context-aware content-provision service. Through the implementation experience of the service, three issues are reported in this paper that are generally important for services in a ubiquitous computing environment. The first issue is that there is a difficulty in handling information in the community in ubiquitous computing environments unlike traditional Internet-based communities. The second issue is that the context-handling mechanism is important in ubiquitous computing environments. The third issue is that the system designer must consider the dynamic device-allocation facilities in the system.
