Abstract:

The RFID middleware is often regarded as the central nerve of the RFID systems. An embedded RFID middleware of lightweight ALE is  constructed by virtue of the embedded systems technology of ARM and Linux. The middleware reserves the key functions of the standard ALE and amends some scalability mechanisms on the basis of maintaining the greatest degree of compatibility for the standard ALE. It is fullfeatured, moduleclear, high degree of independence and good reconfigurability. It meets the needs of the resourceconstrained embedded environment in both the function and the performance, and provides a unified platform for the development of the upper layer application systems. It can integrate the RFID smart devices into the existing application system better, and can bring enormous convenience for developing the RFID applications.
