Research and Implement of Data Integration Middle Ware in Internet of Things Based on RFID Using MAS

In order not to change the existing local database models, providing the global model of databases, by combining the MAS technology and distributed data technology, The virtual integration way based on ontology agent is proposed, the way is relationship database accessing technology, and it is also federal mode.Based on Ontology the global model of distributed database is constructed in the way.In the network environment, The DIAgents are design based on CIAgent SDK, the communication between DIAgents is descripted by KQML language, GDBMS are composed of cooperative DIAgents.Using these technologys, data integration of the oilfield enterprise is realized, the system operation is stable and reliable.
