Abstract
Due to the lack of open infrastructure support, the development of context aware systems in pervasive computing environment is difficult and costly. To solve this problem, we have implemented an open middleware-based context-aware infrastructure for context aware in pervasive computing, named oca-Infrastructure. In oca-Infrastructure, (1) a generic layered model is proposed to specify the functional elements of context-aware computing and provides context-aware computing systems with robust separation of concerns. (2) Wireless CORBA is used to enable distributed components to communicate each other and support for wireless access and terminal mobility. (3) Context-aware supporting platform is created to mask the dynamic environment. (4) Context query is issued based on type-subject model. The context message is delivered in XML. (5) Knowledge-based access control is used to improve security. Finally, we have presented detailed examples to evaluate the feasibility of oca-Infrastructure.
