The rapid growth and development of wireless communication and networking technologies coupled with far more powerful and energy efficient mobile computing systems enable more intelligent behaviours such as user-centric and self-reflection to be used so that mobile user applications can leverage dynamic context information to provide customized services. In this research, an architectural model for the deployment of intelligent context-aware service adaptation process is introduced. A mobile spatial routing application is exploited to demonstrate the improved flexibility and robustness of the new system model.
