Much of the current work on context-aware computing relies on information directly available to an application via context sensors on its local host, e.g., user profile, host location, time of day, resource availability, and quality of service measurements. The authors propose a new notion of context which includes in principle any information available in the ad hoc network infrastructure but is restricted in practice to specific views of the overall context. The context of each view is defined in terms of data, objects, or events exhibiting certain properties, associated with particular application agents, residing on particular hosts, and part of some restricted subnet.
