　　This thesis focuses on the issues of integrating context-aware applications with location technologies, such as the discrepancy reduction, the flexibility of the software development, and the integration of various location and movement information. Besides, some general tasks done in context-aware applications are included. In order to address these issues and help context-aware applications to accomplish their general tasks, a Filter-based and Mobility-Aware Mediator (FBMAME) is proposed as a middleware between the context-aware applications and location technologies. Context-aware applications can exploit this middleware to acquire a user’s location information or movement events easily; developers can also add new filters with special functionalities into this middleware for their applications.
