3 Abstract A study on the network architecture seamless for the ubiquitous communication processing over IP and sensor networks Ichiro TAMURA For the realization of the ubiquitous networking engineers are considering the combination of IP network and RFID But standardization of the cooperation protocol between IP network and RFID is still quite preliminary In this study I propose the network architecture that makes it possible to link IP network and RFID with seamless smoothness There are some differences about connection protocol between IP network and RFID network The problems disturb to link IP network and RFID Therefore the middle layer system that mediates the connection between IP network and RFID is proposed. The system manages the RFID data as Metadata to standardize information obtained when users use RFID tags And the system communicates the RFID tag information as cross-system attribute because it is necessary to decrease the differences between several RFID standards Moreover the system deals keyword searching by keeping RFID tag information The system is evaluated for it s introduction into POS system key words IP network RFID seamless communication ii
