Research of RFID information service based on cloud computing in supply chain
基于云计算的供应链RFID信息服务研究*

Given the problems of existing EPCGlobal network and the demand of information service under supply chain environment,this paper provided an innovative architecture for RFID information service based on cloud computing. This architecture decoupled the local enterprise RFID application from public information service, built a unified cloud-based RFID information service platform with using an information distribution mechanism based on hidden markov model (HMM) to mirror RFID information, finally implemented near real-time, serial-level RFID information service. Finally, compared the architecture with the EPCGlobal network and proved its superiority.
