The behavior of context-aware applications depends on various aspects of the surrounding context. Most context-aware applications are dependent on middleware from the point of how to subscribe and query dynamically changing contexts. This dependency prevents application developers from easily developing context-aware applications because these applications either require knowledge of the internal architecture of the middleware or the help of an administrator. To relieve application dependency on middleware, we propose context communication between applications and middleware. An application communicates with middleware to register rules, which predefine interesting contexts, and to request context queries to acquire information. The context communication can allow application developers to spend time on developing application logic and less time on middleware architecture or its administration. We expect that our work will make it easier for developers to develop various context-aware applications.
