Design of Physical and Logical Context Aware Middleware

The human-computer interaction depended computing mode is evolved to an intelligent adaptive context aware computing. The corresponding middleware should be adaptive, reflective, dynamic reconfigurable and physical/virtual context aware. In this paper the design of a context-aware middleware is discussed. Some key issues involved, e.g. virtual and meta sensors, reflective context model, multi-agent mechanism, an extension of Web Service-Open Web Service, etc. are analyzed and studied. An experimental system and its design are introduced
