A Distributed Supply Chain Discovery Service

Summarizing the main methods of current EPC global network discovery service, aiming at the large-scale RFID applications and the business control needs of the entire EPCIS, and through modeling the EPC events to describe all activities in the supply chain, the paper realizes the unstructured discovery service based on extended ONS. The discovery service can use RFID tags to complete "supply chain tracking", and make the query load balancing, reduce the routing hops and improve the query efficiency through the basic idea of P2P.
