Abstract: This paper proposes an active Radio Frequency IDentification(RFID) system that can work at very low power consumption. It bases on the technology of sensor node and TinyOS operation system in sensor networks. Both high frequency and low frequency radio chips which are controlled by ATMega128 are used to decrease the energy consumption. TinyOS-based software architecture and the implementations of low frequency unit are presented.

Key words: sensor network, TinyOS, Radio Frequency IDentification(RFID)
