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 a middleware and a context server for dealing with context-aware application system in ubiquitous computing. The middleware plays an important role in recognizing a moving node with mobility as well as in executing an appropriate execution module according to context. In addition, the context server functions as a manager that efficiently stores context information, such as user's current status, physical environment, and resources of a computing system. Using them, we implement our application system which provides a music playing service based on context. It is shown to take below two seconds that our application system can detect a user's context and start playing music according to the context.
