Dynamic framed slotted ALOHA (DFSA) protocol has been widely used in many RFID systems. According to the information from last frame (e.g. the number of idle, success and collision slots), DFSA dynamically adjusts the next frame size so as to reach higher identification efficiency. The process is known as tag estimation of DFSA. Similar to most existing tag anti-collision protocols, The DFSA in...
Mobile RFID is a new application that provides a valuable service to users with mobile communication. Current RFID authentication schemes are not viable to use in mobile RFID environment. Since unlike in regular RFID environments, whereas the communication channel between the server and the reader is assumed to be secure, the communication channel between the server and reader in the mobile RFI...
Reader network planning (RNP) problem of radio frequency identification (RFID) system is a combinational optimization problem. In this study, we propose a genetic algorithm (GA) to solve this RNP problem. We have tested the proposed GA on several RNP problems and compare with a particle swarm optimization (PSO) method by solving the same RNPs. The comparison results demonstrate that the propose...
RFID system (Radio Frequency Identification), an automatic identification system relying on exchange of information through radio frequency, is emerging as one of important technologies that find its use in various applications ranging from healthcare, construction, hospitality to transportation sector and many more. This paper describes about RFID technology, concentrating its use in improving...
Several implementations of chipless RFID (Radio Frequency Identification) tags are presented and discussed as low-cost alternatives to chip-based RFID tags and sensors. An overview of present-day near-field electromagnetic tagging is presented, including both chipbased and chipless technologies with associated costs. As a candidate for low-cost ID tags, a design theory and implementation is pre...
In the fields of production, manufacturing and supply chain management, Radio Frequency Identification (RFID) is regarded as one of the most important technologies. Nowadays, Mobile RFID, which is often installed in carts or forklift trucks, is increasingly being applied to the search for and checkout of items in warehouses, supermarkets, libraries and other industrial fields. In using Mobile R...
Recently, the use of RFID(Radio Frequency Identification) for object identification is used more often, but the tag collision problem by the use of a radio frequency still exists. Therefore, in this paper, we analyzed tag identification time to minimize tag collisions and improve tag identification time by applying various tag anti-collision algorithms in the suggested method. As a result, we d...
Radio Frequency Identification (RFID) is an automatic identification (Auto-ID) technology which allows remote interrogation of ID data on RFID tags using radio frequency (RF) as a means of wireless communication between tagged objects and RFID readers. This paper studies whether so called ”networked RFID” systems can meet the timing constraints set by real-time industrial control applications. ...
many countries have created systems for monitoring food products. however, these systems need paper and label and also, cannot find the origin and final destination of food product. radio frequency identification (rfid) has the capability of monitoring foods completely and track the mentioned points. this technology also can monitor many food products simultaneously. the usage of this system ca...
In Today's world RFID (radio frequency identification) technology is one of the most popular technologies for tracking and tracing, whereby a person or an object is identified using Radio Frequency (RF) transmission using a special kind of a sensor network. Recently, radio frequency identifications (RFIDs) are used to identify the assets which are permanent objects used internally in business. ...
