The Effective Method for Distributed Information Gain in EPC Network

Abstract

Automatic object identification and distributed computing technology have been used to realize a ubiquitous computing environment. Radio Frequency Identification (RFID) technology has been applied to many business areas such as logistics and supply chains. EPCglobal, which is currently focusing on developing a worldwide standard for RFID, has proposed an open global standard named the EPCglobal network (EPC Network). The amount of communication between each component affects the performance of the EPC Network considerably, because RFID application systems get information from sub-systems of the EPC Network, consisting of the Application Level Event (ALE), Object Naming Service (ONS), EPC Information Service (EPCIS), and EPCIS Discovery Service (EPCIS DS). Therefore, RFID application developers should consider how to communicate with one another, as this is crucial for achieving good performance of RFID application systems in an EPC Network. This paper proposes a method for obtaining distributed information effectively in an EPC Network, and the use of this method results in a reduction of 78 % in the maximum processing.
