Conference Object Citation - Scopus: 1Indoor Location Finding Algorithms for Mobile Robots Carrying Passive Rfid Tags(2012) Özyurt,E.; Aydin,E.; Yapici,A.C.Precise localization of mobile robots is critical issue in military, industrial and show business applications. In the literature, several localization techniques has been proposed, in which reader is carried by the mobile object. But in this study a passive Radio Frequency Identification (RFID) tag is attached to mobile robot and the reader antennas being dispersed around the environment. This novelty protects the mobile robot from an increase of weight and results in saving in battery consumption. Also by this way, an increase in mobile object requires a mere increase in low cost passive RFID tags in the navigation system. We have applied a signal pattern matching algorithm, Weighted Centroid Localization (WCL) and Selective Adaptive Weighted Localization (SAWCL) algorithms to locate the tag via Received Signal Strength Indicator (RSSI) and we compare the results. In this study a pilot application is implemented and a prototype is developed to show the proof of concept of the system. © 2012 IEEE.Conference Object Reader Antenna Design for Rfid Applications;(2013) Kaynakö,G.; Kzlu,N.; Kapusuz,K.Y.; Can,S.; Aydzn,E.In this paper, a coplanar waveguide (CPW) fed microstrip patch antenna is designed on finite element method based simulation program and fabricated in order to use reader antenna in Radio Frequency Identification (RFID). The results of the simulations and the produced antennas are presented in the study. The produced microstrip patch anten na has a 105MHz bandwidth and operates in between 895-1000 MHz . © 2013 IEEE.Article Citation - WoS: 10Citation - Scopus: 12An Intelligent Indoor Guidance and Navigation System for the Visually Impaired(Taylor & Francis inc, 2022) Kahraman, M.; Turhan, C.Intelligent guidance in complex environments where various procedures are required for navigation is critical to achieving mobility for the visually impaired. This study presents a newly developed software prototype with a hybrid RFID/BLE infrastructure to provide intelligent navigation and guidance to the visually impaired in complex indoor environments. The system enables the users to input their purpose via a specially designed user interface, and provides intelligent guidance through a chain of destination targets which are determined according to the inherent procedures of the environment. Path optimization is performed by adaptation of the traveling salesman problem, and real-time instantaneous instructions are provided to guide the users through the predetermined destination points. For evaluation purposes, a hospital environment is constructed as an example of a complex environment and the system is tested by visually impaired participants. The results show that the intelligent purpose selection and destination evaluation mechanism modules of the system are found to be effective by all the participants.Conference Object Reader Antenna Design for Rfid Applications(Ieee, 2013) Kaynakoz, Goktug; Kilic, N.

In this study AHP (Analytic Hierarchy Process) and FAHP (Fuzzy Analytic Hierarchy Process) are used to choose between Barcode and RFID systems for the company warehouse data collection system. This decision is affected by four criteria which are: cost, functionality, sustainability and performance. The barcode system was preferred by 68 % and RFID was preferred by 32 % according to AHP. For FAHP, barcode system was preferred by 72 % and RFID was preferred by 28 %. Consequently AHP values are consistent with FAHP values. Finally barcode system is selected for the company's warehouse data collection system and FAHP is found to be relatively more sufficient in terms of description of this decision-making process because of its fuzziness and vagueness compared to AHP method.Conference Object Citation - Scopus: 5An Rfid Based Location Finding and Tracking With Guidance(2008) Oktem,R.; Aydin,E.U.; Cagiltay,N.E.This paper tackles an RFID based location finding and tracking system. The system is an integral part of a navigation aid being developed for guiding visually disabled people in a store. The aid is composed of a portable hardware interface unit, a standalone RFID unit, and a central processing unit. The units interact via wireless communication to locate the position of the user in a known indoor environment and tracking his/her movement. An active RFID tag helps to estimate the location of a user and the user is guided to follow a route accordingly, via a tactile compass. The system uses RF signal strengths and is based on Bayes Decision Theory. Initial simulation results with the system prove promising for location finding and tracking, especially when the tracked person is guided by a system. © 2008 IEEE.Article Citation - WoS: 11Citation - Scopus: 16Improving Baggage Tracking, Security and Customer Services With Rfid in the Airline Industry(Budapest Tech, 2010) Mishra, Deepti; Mishra, Alok; Computer Engineering; Software EngineeringRadio frequency identification (RFID) has been identified as one of the ten greatest contributory technologies of the 21(st) Century. This technology has found a rapidly growing market, and an increasing variety of enterprises are employing RFID to improve the efficiency of their operations and to gain competitive advantage. In the aviation industry, major airports/airlines have been looking for the opportunity to adopt RFID in the area of baggage handling for a long time. Many pilot tests have been done at numerous US., European, and Hong Kong airports. RFID tags were found to be far more accurate than bar codes, and their performance was also measured to be well above that of bar codes. This paper presents the state of RFID adoption planning, architecture and implementation at a major airline, with a special focus on improved services due to improved baggage handling, on increased airport/airline security and on frequent flier program services. This is accomplished by integrating RFID technology together with networking and database technologies.
