The design of efficient and reliable data transmission mechanism applied in vector control system

Vector control system is mainly on items management and positioning, it is essentially the management of RFID tag attached to items. For the problems of the data transmission security which is not guaranteed and relatively low transmission efficiency of the large data flow when tag data stream transfers from the data collection terminal to the upper business end for general RFID systems. This paper design an efficient and reliable data transfer mechanism. The mechanism uses data compression and encryption mechanisms to ensure the responsible transmission of vector control system of data collection RFID middleware to provide messaging services business for the upper end of the message bus ActiveMQ efficient and reliable transmission of data streams. Before transferring data, through the compressing of tag data to ensure the efficient transmission of data; when transmitting data, by introducing ECDH key agreement and the Trivium stream encryption in data transmission of data streaming of both sending and receiving sides of tag data to ensure safe and reliable transmission of messages. By comparative tests we find that transmission efficiency is significantly higher by the introduction of the transport mechanism comparing to the direct transmission of data.
