APPLICATION MOBILITY IN ACTIVE SPACES

Abstract

Abstract. The vision of Ubiquitous Computing is that of users naturally interacting with their environment to access digital data and applications. The digital world is finally merged with the physical world and users can interact with it to perform a number of tasks. However, one of the requirements of this vision is the ability to build and run applications that are not bound to a specific device. These applications are associated with a user and have the ability to move with the user and adapt automatically to different environments. We present in this paper an application framework and an associated system software infrastructure to support the development of mobile applications. We provide two types of mobility support: inter-space mobility to move applications across different spaces, and intra-space mobility to move the components of an application to different resources present in the user’s current environment. 1.
