Implementation and Evaluation,ults have shown that the implementation’s performance is appropriate to the target scenario. The event engine of the middleware is based on a distributed event-based system called Naradabrokering. In particular, the middleware adopts Naradabrokering’s XML engine. Context information is represented a

This work explored this concept and presented three additional contributions: a primitive to describe context interests of variable wideness, the design and implementation of a middleware that support context domains, and a categorization of

The scenario demonstrates aspects of actual ubiquitous applications, such as interoperation across diverse environments of context-aware computing. The application is a location-aware messaging application, and it is applied to a tourist scenario.
