A Performance Improvement to the Web Services-Based RFID Middleware

With a widely deployed RFID middleware system either in companies or manufactories, large volumes of collected data can be integrated into enterprise information management system. By combing the technique of Web services, RFID information flow can be exchanged between different information platforms under the universal XML format. However the performance of data transmission causes great concern of researchers. Several methods and strategies have been proposed to improve it. In this paper, we design a context-store and apply it to the exchange process of SOAP messages between mobile terminal and server. Experiments show our approach has reduced the average response time compared with the previous methods. Moreover, in the manufactory, with the improved Web services-based RFID middleware system, the production efficiency greatly increases.
