Location awareness significantly enhances the functionality of ubiquitous computing services and applications, and enriches the way they interact with users and resources in the environment. Many different alternative or complementary location sensing technologies are available. However, these technologies give location information in different formats and(More)
Pervasive computing promotes an environment that blurs the distinction between digital and physical devices and integrates all entities in a physical space into a cohesive programmable unit. Some of the early research activities in pervasive computing focused on developing infrastructures for pervasive applications. These infrastructures successfully merged(More)
Pervasive computing advocates the enhancement of physical spaces with computing and communication resources that help users perform various kinds of tasks. We call these enhanced physical spaces Active Spaces. Active Spaces are highly dynamic - the context and resources available in these environments can change rapidly. The large number of entities present(More)
Pervasive computing envisions an environment that seamlessly integrates digital and physical devices. Users can access digital data and applications from the environment as easily as accessing them through their computers. Since pervasive computing exists in the user's environment, the technology is sustainable if it is invisible to the user and does not(More)
Ubiquitous computing envisions an environment where physical and digital devices are seamlessly integrated. Users can access their applications and data anywhere in the environment. Applications are not bound to any single device and can migrate with the user to different environments. Therefore, application mobility is an important aspect of ubiquitous(More)
In previous work [M. Roman et al., (2002)], we introduced a distributed middleware infrastructure for managing physically-bounded, standalone pervasive computing environments, which we refer to as Active Spaces. We extend this middleware to support the organization, management and interactions of large-scale pervasive computing systems built from multiple(More)
Ubiquitous computing enables an environment that assimilates digital and physical devices seamlessly and presents a unified programming interface to the user. Users can program the environment similar to programming a computer. With the widespread availability of personal devices and personal area networks, there is a growing need for personal devices to(More)
