A review of recent developments on secure authentication using rf fingerprints techniques Hüseyin Parmaksız, Cihan Karakuzu Sakarya University Journal of Computer and Information Sciences, 2022 The Internet of Things (IoT) concept is widely used today. As IoT becomes more widely adopted, the number of devices communicating wirelessly (using various communication standards) grows. Due to resource constraints, customized security measures are not possible on IoT devices. As a result, security is becoming increasingly important in IoT. It is proposed in this study to use the physical layer properties of wireless signals as an effective method of increasing IoT security. According to the literature, radio frequency (RF) fingerprinting (RFF) techniques are used as an additional layer of security for wireless devices. To prevent spoofing or spoofing attacks, unique fingerprints appear to be used to identify wireless devices for security purposes (due to manufacturing defects in the devices' analog components). To overcome the difficulties in RFF, different parts of the transmitted signals (transient/preamble/steady-state) are used. This review provides an overview of the most recent RFF technique developments. It discusses various solution methods as well as the challenges that researchers face when developing effective RFFs. It takes a step towards the discovery of the wireless world in this context by drawing attention to the existence of software-defined radios (SDR) for signal capture. It also demonstrates how and what features can be extracted from captured RF signals from various wireless communication devices. All of these approaches' methodologies, classification algorithms, and feature classification are explained. In addition, this study discusses how deep learning, neural networks, and machine learning algorithms, in addition to traditional classifiers, can be used. Furthermore, the review gives researchers easy access to sample datasets in this field.
The Monitoring of Monthly, Seasonal and Yearly Optimum Tilt Angles by Raspberry Pi Card for Bilecik City, Turkey Harun Ozbay, Akif Karafil, Yasemin Onal, Metin Kesler, Huseyin Parmaksiz Energy Procedia, 2017 Solar energy is extracted from photovoltaic (PV) panels by semiconductor materials used in the system. However, the PV panel efficiency is low. Moreover, inaccurate determination of optimum fixed tilt angle of the panels, some environmental factors such as dirt and dust and solar radiation level and temperature variations depending on the seasonal changes decrease the panel efficiency. In the study, PV panels were placed at 10°, 20°, 30°, 40°, 50° and 60° tilt angles and the monthly, seasonally and yearly optimum tilt angles for Bilecik city were determined. Therefore, it was determined at which tilt angle the maximum power is extracted from PV panels. The record and the storage of the voltage, current and the power data obtained from PV panels is provided by Raspberry Pi card. Moreover, the obtained data is open to access on the internet by a web server set up on Raspberry Pi. Therefore, the data can be watched live in any computer with an internet access. Annual measurements were performed by the designed system and the data was recorded with the date and time data.
Calculation of optimum fixed tilt angle of PV panels depending on solar angles and comparison of the results with experimental study conducted in summer in Bilecik, Turkey Akif Karafil, Harun Ozbay, Metin Kesler, Huseyin Parmaksiz Eleco 2015 9th International Conference on Electrical and Electronics Engineering, 2016 Sunlight incidence angle varies throughout the year due to the rotation of the earth around its own axis and its elliptical orbit. While sunlight falls to the earth with steep angle in summer in the Northern Hemisphere, it falls with shallow angle in winter. Sunlight should fall with steep angle to extract maximum power from PV panels. Therefore optimum fixed tilt angles of PV panels should be changed monthly and seasonally. In the mathematical analysis of the study, the monthly, seasonal and the annual optimum fixed tilt angles of PV panels depending on solar angles are calculated for Bilecik city. In the experimental study, optimum fixed tilt angles for May, June, July and August are determined by PV panels placed at 10°, 20°, 30°, 40°, 50° and 60° tilt angles. The mathematical analysis results are compared with the experimental results.
