Abstract: For the ubiquitous shortcomings of weak event handler and poor real-time in the RFID middleware, we propose the RFID middleware three-tier data processing model based on complex event processing (CEP). The core technologies of complex event processing are rule definition and event detection. The difficulty of rule-making lies in identifying the parameters and adapting to the changing needs. In view of this, this paper proposes an adaptive rule model, and elaborates on the process of its implementation.
