Design and Implementation of a RFID Reader/Router in RFID-WSN Hybrid System

Abstract

In order to put Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) in a hybrid system, this paper presents the design and implementation of a RFID reader/router that can obtain information of both RFID tags and WSN sensor nodes and transmit the information through the WSN to the PC server. The RFID reader and WSN router are combined with both hardware and software. In hardware structure, CC2530 is used as micro controller and RF module for ZigBee wireless communication, and MF RC522 is used as reader RF chip. The software deals with both identity and sensing information and controls the routing. Experiment results show that the RFID reader/router achieves long distance identification, flexibility, scalability, and low cost. It also provides reliable and secured data transmission and broadens the communication range and application scope of RFID readers.

A Review of IoT Sensing Applications and Challenges Using RFID and Wireless Sensor Networks

“…The previous sections have shown why RFID and WSN are two fundamental pillars that will enable new promising IoT applications [3]. This section presents two technological trends for new IoT applications.…”

“…There are three levels of integration among RFID and WSN producing three different architectures [3,59]-RFID tags with WSN nodes, RFID readers with WSN nodes, and a hybrid integration (see also Figure 4).…”

“…These devices are smart but simple objects with sensing and wireless communication capabilities [1,2]. In this framework, two technologies are mainly used, and are becoming the two fundamental pillars of the IoT: radio frequency identification (RFID) and wireless sensors networks (WSNs) [3]. Both technologies are focused on wireless sensing and communication, which are the two main needs of the IoT.…”

“…The sensing nodes collect the information from their respective sensors and communicate with a PC server through the gateways. WSNs are widely used in medical, environmental, military, and security applications [3].…”

A WSN Clustering Multi-Hop Routing Protocol Using Cellular Virtual Grid in IoT Environment

“…Wireless Sensor Networks (WSNs) are widely used in marine environmental monitoring, mine monitoring, and medical monitoring. In the wireless sensor network, the nodes are powered by the battery, so the service life of the whole network is limited [1,2]. In the key technologies of WSNs, routing technology plays an important role.…”
