Wireless Sensing with Radio Frequency Identification (RFID): Instrumental in Intelligent Tracking

摘要

Currently, all technologies and associated applications based on Internet of things (IoT) facilitate the user mobility and likely to contribute immensely in all future mobile applications. Radio frequency identifications (RFIDs) along with wireless sensor networks (WSNs) have potential to offer a great value addition on IoT platforms. Intelligent RFID tags powered through independent energy sources when attached to an object and networked through a wireless link allow seamless integration of some of the physical parameters like humidity and temperature in addition to their location data with the user information system on the IoT [1]. This paper provides a brief insight of the RFID technology with its sensing capabilities. It reviews design considerations of RFID-driven wireless sensors from their implementation perspective. It has primarily focused on intelligent operational logistics and its monitoring which have tremendous potential for both civil and defence logistic applications. A two-layer data networked architecture of RFID has been introduced over IoT platform in the proposal which is comprised of an asymmetric RFID tag-reader connectivity along with the interconnected RFID readers linked through the Wi-Fi or cellular networks [2]. This paper also discusses that how ultra wide band (UWB) RFID is considered today as a promising technique for cost-effective wireless sensing and ultra-low power mobile applications.
