A Distributed RFID Discovery System: Architecture, Component and Application

For performance and security concern in large-scale application environment, based on "follow the chain" mode, a distributed RFID discovery system is proposed and implemented. At first, system architecture is given. Secondly, core components, such as query engine, local cache and client, are formally specified with TIOA. Experiments on query execution time and accuracy show that this distributed discovery system is more suitable for large-scale RFID applications. The proposed system is also verified by a practical project "Beijing Volunteer Card Management Platform".
