Distance Learning Media Content Pervasive Environment For Technology Research,

With the rapid development of computer technology, network technology has become the mainstream of modern educational technology. At the same time, the rapid development of computer , network and communcation technology ,the applied scope of pervasive computing systems is expanding in high speed. New network-based distance learning has become a new trend. Under these conditions I studied the problem of access to media content of distance learning system for pervasive computing systems in this paper.From the points of distance learning in the pervasive computing environment, I adopt the method of combination of theory and practice and elaborate on technical difficulties of long-distance teaching for pervasive computing systems. For problem of access to media content, I provide the system framework of overlay network of media content semantics and build routing network of hierarchical semantics, and then provide specifications of realizing the building and maintenance of route in switching from hierarchical semantic route.I solve the problem of access to media content of distance learning system in the pervasive computing by the analysis and design in this paper, so that which can better meet the pervasive computing environment.
