RFID Adaptor for Detecting and Handling Data/Events in Internet of Things

The Internet of Things (IoT) remains that things will be able to detect information from the environment, and communicate with the physical world. We previously proposed middleware to integrate and interoperate information based on the DDS standard. The proposed middleware consists of REST, Zigbee, and RFID adaptors. It allows the adaptors to share information by data/events/services topic matching. In this paper, we propose an RFID adaptor for RFID tags' data/events in the IoT as a part of the middleware. The adaptor publishes data/events topic among data/events/services considering the characteristics of RFID technology. Employing the publish-subscribe model of the DDS, the RFID adaptor can detect data from RFID tags and publish the data/events to the DDS. Other adaptors in the middleware can then subscribe the data/events. As a simulation of the RFID adaptor, we can identify the interoperation of RFID and DDS. Through applying the RFID adaptor in IoT environment, it can interoperate data/events of other applications in IoT.
