Reconfigurable Industrial WSN in IoT Environment with Smart Sensor Interface Using FPGA

Abstract

IEEE1451 is set of standards developed by IEEE for connecting transducers to microprocessors, instrumentation systems, or control networks. These standards define TEDs for each transducer connected to system. TED stores transducer related information in memory like EEPROM. Wireless sensor network is network of distributed sensors that monitor environmental parameters and cooperatively pass data to main location through network. IEEE1451 defines standards for connecting actuators to processor in WSN. Internet of things defines the network of objects surrounded by sensors, electronics, software, and network capable processors. Wireless sensor network works at physical layer of IoT. Sensor interface device is required to collect sensor data in internet of things. Traditional sensor interface device are not truly parallel in sensor data acquisition. In this design, FPGA is adopted as a sensor interface device with corresponding IEEE1451 protocols
