Research on convergence theory of RFID and WSN

RFID and WSN technologies originated relatively independently,and the mix of both was rarely considered.The paper begins with the elaboration of three kinds of RFID and WSN integration,and gives typical structure of various fusions.Secondly the paper discusses the key technologies of routing applied in the process of integration,middleware and data integration and gives both RFID and WSN fusion to form the the WSID network.Finally,the WSID network development direction is summarized,which is expected to lay the foundation for further research.
