The mobile and ubiquitous computing has been stimulated by the widespread diffusion of mobile devices, wireless networks, and, more recently, by location systems. In this context, applications are emerging in different areas, such as, education, entertainment, and commerce. The application of the ubiquitous computing in the exploration of business opportunities is called Ubiquitous Commerce. This...
GlobalEdu is a generic model created to support learning in ubiquitous computing environments. This model has the necessary support to implement learning-related functionalities in ubiquitous environments. The basic ubiquitous computing support must be supplied by a middleware where GlobalEdu lays atop. This paper proposes the integration of GlobalEdu with two middlewares: ISAM and LOCAL. ISAM supports...
The ubiquitous computing scenario brings many new problems such as coping with the limited processing power of mobile devices, frequent disconnections, the migration of code and tasks between heterogeneous devices, and others. Current practical approaches to the ubiquitous computing problem usually rely upon traditional computing paradigms conceived back when distributed applications where not a concern...
