Research On The Core Technology Of Pervasive Computing Based On OSGI

The world today is taking on an unprecedented growth in Information Technology.As the personalinformation become more and more ,how to do with the personal information ,how to gain a mastery of Information is facing the people. With the development of the computing technology and the Communication technology, difficulties people faced can be resolved. The post-PC era is coming, when all the connected computing device can be as easily accessible as the water , electricity. papers and pens. As computation can happend in anywhyere, during anytime and on any device, so there is a revolution in the way how human beings use computers ,and this revolution turns such way from computer-center into human-center.Base on the OSGI Specification which is released by the Open Service Gateway Intiative, this dissertation come up with the distributed model -Bundle System.In this dissertation, the author creates the System architecture.gives the System structure model.analyze the System function.Finally.the author design and implement the main module.The main contribution of the author in the dissertation could be concluded as:1. Base on the OSGI Service Frame Work,the author come up with the concept of the Bundle System.2. the author gives the namespace of the Bundle System,creates the System architecture.3. Base on the creating of the Bundle System Architecture,the author gives the Systtem Structure Model,analyze the System function,concludes the function pattern.4. The author use the The Unified Modeling Language to express the dynamic behavior model.5. the author design and implement the main model.
