WSN and RFID Integration in the IoT scenario: an Advanced Safety System for Industrial Plants

The paper proposes and discusses the integration of WSN and RFID technologies in the IoT scenario. The proposed approach is based on the REST paradigm, thanks to which the two technologies can be seamless integrated by representing sensors, actuators and RFID related data as network resources globally addressable through state-of-the-art IoT protocols. The integration approach is detailed for the Smart Factory use case by proposing and developing an advanced IoT-based WSN and RFID integrated solution aiming at improving safety in industrial plants. The developed system can guarantee a safe access to factory dangerous areas in which safety equipments are required. In the paper, the system design is first presented, then, all the developed hardware and software solutions are described before presenting system performance results in a real test bed. System performance are reported in terms of response time and accuracy for authorization control and location tracking applications.
