Adding IEEE 1451 Transducer Capability to EPCglobal Information Service

There are many researchers devote themselves to design Internet of Things (IoT) architecture and study related enabling technologies such as RFID and transducers. As we known, EPCglobal defines a collection of standard specifications utilizing RFID technology to support identification applications. And IEEE 1451 is a series of smart transducer standard to provide a unified way to access any type, manufacturer, and wired or wireless sensors and actuators. We have proposed some methods of integrating IEEE 1451 compatible transducer capability to EPCglobal such as a consistent raw data expression and ALE middleware extension. In this paper, we put emphasizes on adding transducer capability to the exchange layer of EPCglobal - EPCglobal Information Service (EPCIS). A transducer event is introduced to extend EPCIS for adding transducer capability and cooperates with the capture and query services of original EPCIS. EPCIS event repository must be extended to store transducer events also. By cooperating with identify and capture layers of extended EPCglobal, an IoT architecture based on international standards is built.
