Integrating Context-aware Pervasive Environments

Context-awareness is an important issue of pervasive computing applications and ultimately environment. These applications enhance the functionality of pervasive computing services, applications and systems. In this paper we have proposed a novel design of middleware for global pervasive environment. The focus is made on quality of service, reliability, performance efficiency and precision of the applications/knowledge to be used in fulfilling the user request. The proposed middleware is actually a service oriented framework in which data mining is used for knowledge discovery, context is identified by using more precise approach, and then automatic service discovery, activation and execution takes place to facilitate the user in pervasive environment. The paper also focuses on the seamless integration of technology in our daily life, which is also the core of ubiquitous computing. Semantic Web (semantic Web services) is the concentric point in the paper as it is used for the presentation of the domain knowledge and context in an ontological fashion. There is also a need of integrating these standards using a middleware infrastructure to ensure seamless integration. In addition to interoperability of different systems, the proposed middleware manages the knowledge and service oriented flow of the system. The system facilitates the separation between applications and service oriented technologies to enable dynamic add-on of new technological achievements, without changing existing applications
