Middleware for Context Management Based on Context Domains

Abstract

Context management based on context domains is an approach for supporting interests of variable wideness in distributed and dynamic environments. Context domains establish distributed boundaries for both context modeling and management. The design of a distributed middleware based on this concept should address an architecture that enables efficient context-based interaction in both localized and distributed pairs of consumer–provider, protocols for discovering context management systems, and a suitable programming model for context-aware applications. In addition, the middleware should address some additional requirements, such as its usage in resource-constrained portable devices.
