Abstract

Context-awareness is a technology to facilitate information acquisition and execution by supporting interoperability between users and devices based on users' context. In this paper, we design and implement a middleware and a context server for dealing with context-aware applications in pervasive computing. The middleware plays an important role in recognizing a moving node with mobility by using a Bluetooth wireless communication technology as well as in executing an appropriate execution module according to the context acquired from a context server. In addition, the context server functions as a manager that efficiently stores into the database server context information, such as user's current status, physical environment, and resources of a computing system. To verify the usefulness of the middleware and the context server, we finally develop our context-aware application system which provides users with a music playing service in pervasive computing environment.
