Complex event process infrastructure in mobile distributed system

With the growing success of the mobile computing devices, such as laptop computer, third generation mobile phone, personal digital assistant, many current and emerging distributed applications present challenging problems to the RFID complex event processing architecture. The traditional architecture of central complex event processing should be reconstructed and the new architecture should show a coherent global view. This paper proposed a infrastructure of mobile distributed complex event processing model which enables automatic and real time routing, caching, filtering, aggregation and processing of RFID event. Different form RFID middleware, it's a lightweight platform and can extend to cloud level. The implementation of the architecture in practical scene is also discussed. To enhance the real time performance and the efficiency of complex event processing, we designed a priority based on event scheduling algorithm and event repository cache strategy.
