Advanced EPC Network Architecture Based on Hardware Information Service

Object traceability based on Radio Frequency Identification(RFID)is an important capability of the Internet of Things(IoT).GS1 EPCglobal,a de-facto standard in RFID technology,develops Electronic Product Code(EPC)network architecture,which mainly includes EPC Information Service(EPCIS),Object Name Service(ONS),and Discovery Service(DS).This architecture is used to capture and share standardized events representing various aspects on EPC object.However,the EPC network architecture also faces challenges;for example,the separate management of unrelated event data and master data may increase time consumption when an application extracts valuable information by combing them.A Hardware-Based Information Service(HIS)device is raised in this paper,which is installed on the specific EPC tagged object directly and this could alleviate the problem above.The HIS could store the event data and master data related to the EPC identifier centrally and the application could gain the basic information based on the data stored in the HIS without utilizing ONS,DS and EPCIS.
