Design of Smart Nodes for RFID Wireless Sensor Networks

Wireless Sensor Networks (WSNs) and Radio Frequency Identification (RFID) are the two most important technologies in pervasive computing. Because of their different applications, researchers tend to research them respectively. This paper presents a new architecture for the integration of these two technologies, which is called RFID Wireless Sensor Networks, and gives the design of hardware circuit and software structure of smart nodes. Finally, we realizes the function of monitoring environment on the basis of a low-power microprocessor MSP430F5437, a RF transceiver CC2420, a RFID reader CC2500, and temperature, humidity, light intensity and pressure sensors.
