With the rapid advances in mobile computing technology, there is increasing demand for disseminating information to large numbers of clients with wireless network. The service model, which supports such mobile communication environments, should be scalable, flexible, and cater to the limited bandwidth of mobile clients while providing real-time guarantees. In this paper, we present high-level design of an adaptive real-time publish-subscribe model for mobile communication environments. To express the model and the underlying work mechanism, we define four primitives: publish, subscribe, activate and deactivate. Furthermore, we discuss how to achieve the adaptability and real-time property in the model. Primary simulation study shows that the service model is feasible and well suited to address the requirements of mobile computing. In conclusion, we identify some open problems and our future work.
