Driven by the development of the mobile Internet and the emergence of heterogeneous mobile devices, context-aware applications are attracting growing interest. Based on the idea of transparent computing, the authors propose a novel context-aware service provision (CASP) architecture to transparently and actively provide suitable services to clients. In this article, they present the system model and describe a series of key technologies in CASP, including the client parameter acquisition scheme, the user behavior analysis approach, the service choice algorithm, and the transmission optimization method. Based on the established architecture, they developed software and ran a performance evaluation, proving that CASP offers a good user experience and outstanding generality.
