摘要 提出了一种三层结构的新型RFID-WSN模型,以ST(Sensor-Tag)节点-RR(Reader-Relay)节点-基站为主要组成部分,包括信息收集层、信息过滤层、信息分析层三层结构,利用XML文件格式,用信息收集层中的算法1筛选数据包,用信息过滤层的算法2通过对权值(Quality)和传输原始数据的次数Uni的对比,在步骤Tx_kill(ni)过滤掉冗杂数据,在信息分析层中的算法3中对阈值α,γ的设定决定数据包传输队列和均值.最后通过案例展现该模型的工作方式和优越性. The paper proposes a novel RFID-WSN model with three-layer structure which consists of ST(SensorTag)node,RR(Reader-Relay)and the base station.It includes information collection layer,information filtering layer and information analysis layer,and uses XML file format.In the information collection layer,the algorithm1 implements the function of filtering packet.In the information filtering layer,in step Tx_kill(ni)of the algorithm 2the redundant data is filtered out by comparing the quality and the times of transmitting original data Uni.In the algorithm3 of information analysis layer,setting threshold value determines the transmission queue and average of packet.Finally,the example shows the way of working and superiority of the model.
