WSN节点定位算法与RFID在食品安全监测中的应用

WSN Node Localization Algorithm and the Application of RFID in Food Security Monitoring

在论述RFID射频技术和WSN无线传感器网络技术的基础上,提出将RFID射频技术与WSN技术相结合的方法,解决WSN与RFID技术的融合问题和节点设计问题,根据食品安全检测中的实际情况,引入新的WSN单元蜂窝网络节点定位算法,并采用WSN单元蜂窝网络定位算法与RFID技术相结合的方式。并且设计实现RFID标签和WSN节点相融合以及RFID阅读器与WSN节点相融合,达到基于RFID传感器网络技术在食品安全质量监测中应用的目的。并通过实际以低成本的RFID标签融合RFID射频技术与WSN无线传感器网络技术,对物联网的发展具有技术应用价值。

Based on the discussion on technologies of Radio Frequency Identification （RFID） and Wireless Sensor Network （WSN） , a novel method was proposed to combine RFID and WSN, which solved the fusion and node design problems of RFID and WSN. According to the practical situation in monitoring food security, a new WSN node localization algorithm was put forward based on cellular networks. The goal of applying RFID and WSN in food securing monitoring was achieved by the design of the fusion between RFID tags and WSN nodes and between RFID reader and WSN nodes. The low cost RFID tags have incorporated RFID technology with WSN technology, which will be useful for the development of Intemet of things.
