摘要
为了提高射频识别(RFID)系统的能量利用效率,在无线传感器网络节点结构的基础上,提出一种改进方案,将RFID读写器集成到传感器节点中,取代原有的传感器模块,形成读写器智能节点,并利用传感器节点的节能控制机制实现RFID系统对有限能量的高效利用。以SK—WSN—I无线传感器网络节点和SK—RFID—TRF796X—II读写器模块作为实验平台,进行Matlab仿真,验证了改进方案的节能效果。
In order to improve the energy efficiency of RFID system,an improved scheme based on the architecture of wireless sensor networks(WSNs)node is proposed.The scheme integrates RFID reader into wireless sensor node to replace the original sensor module,and form intelligent reader node.The energy-saving control mechanism of sensor node is used to make efficient use of the limited energy of RFID system.Matlab simulation results based on the experimental platform of SK—WSN—I WSNs node module and SK—RFID—TRF796X—II reader module show that energy-saving effect is improved in the proposed scheme.
