A Middleware-based Approach for Context-aware Computing

Ubiquitous computing environments integrate a large number of heterogeneous devices, which convey an increasing level of complexity when developing ubiquitous applications. A solution to this problem resorts to the use of a software abstraction layer, known as middleware, which encapsulates the underlying elements of the environment and offers unified and standardised access to applications which need to make use of the resources of the environment. Moreover, a middleware layer can also provide high-level built-in services, such as context management services.Ministerio de Educación y Ciencia TIN2006-15617-C0
