A Pervasive View in Distributed Mobile Computing

摘要

The next years will be characterized for high levels of mobility, heterogeneity and interactions among devices connected to global networks. These interconnected networks will use as much wired connections as wireless. The first researches involving wide-area distributed systems answered many questions concerning resource management, although they fail in treating questions related to heterogeneity and dynamic adaptation. More recent works, through technologies like CORBA and Java/Jini, deal with heterogeneity problem, but do not deepen into adaptability aspects. In this article, we propose inside of the project ISAM, a treatment of this subject. ISAM contemplates an integrated approach of software and execution environment addressed to the administration of adaptation in heterogeneous networks, supporting the logical (software) and physical (hardware) mobility, oriented to the execution of distributed applications in a global scale and based on software components.
