On Design Framework of Context Aware Embedded Systems

The primary goal of embedded systems is “Human-centered computing,” that is providing service anywhere, anytime, and automatically. While electrical devices become smaller and smaller and more powerful, context awareness becomes more and more important for embedded systems. Although some of the later systems have been developed with context awareness in mind, how to design a context aware embedded system systematically is still an issue that eludes researchers in the field. This study introduces the importance of context awareness in today’s embedded systems, divides the design of context aware systems into context aware applications and infrastructure. It further applies aspect orientation in the design of context aware infrastructure to model the architectural/system from the developer’s point of view. We show that applying aspect orientation in the development of context aware embedded systems is feasible and has real potential.
