A Comprehensive Analysis of Vendor-Neutral Network Management Strategies Zeljana Loncarevic, Stefan Stankovic, Ranko Petrovic 2024 32nd Telecommunications Forum Telfor 2024 Proceedings of Papers, 2024 The ongoing advancement of computer networks toward efficient configuration of numerous devices has been driven by innovations in management and control technologies. Considering the limitations of the Command Line Interface (CLI) and Simple Network Management Protocol (SNMP), the Internet Engineering Task Force (IETF) developed the Network Configuration Protocol (NETCONF). This protocol provides cross-vendor and interoperable solution for manipulating configuration states and leverages the Yet Another Next Generation (YANG) data models to describe network elements. This paper proposes an educational analysis of the capabilities for device configuration via the NETCONF protocol and YANG data models. The scope of the analysis is to illustrate the flexibility of the NETCONF protocol and the range of network features addressed by vendor-neutral models such as OpenConfig and IETF YANG models within contemporary networking environment.
Educational Platform for Examining the Influence of the Simulated Satellite Link on Overall Communication inside of Different IoT Systems Ranko Petrović, Dejan Simić, Stefan Stanković, Miroslav Perić 2023 International Conference on Advanced Technologies Systems and Services in Telecommunications Telsiks 2023, 2023 Educational platforms are generally of great importance in the education process of students of technical sciences, because the increase of their practical knowledge is enabled through the experimental work. Such platforms are even more significant when considering highly specialized systems, such as IoT systems that rely on satellite link communication, because training courses at real systems in these cases are impractical for many reasons. One example of these educational platforms was developed and implemented at the Vlatacom Institute for the needs of technical sciences students during their mandatory internship. The aim of this specific educational platform is to provide the possibility to examine the influence of the simulated satellite link on overall communication inside of different IoT systems.
Implementation of GRE Tunelling on low cost SoM Stefan Stankovic, Zoran Cica, Dejan Drajic, Ranko Petrovic, Miroslav Peric 2022 30th Telecommunications Forum Telfor 2022 Proceedings, 2022 At the present times, many companies are engaged in the development and implementation of customized solutions for secure communication and traffic encryption. One such device comprising multiple subsystems is being developed at the Vlatacom Institute. One of its main subsystems is the routing system that supports GRE tunneling. The GRE tunneling solution should be absolutely safe and implemented on low-cost hardware. This paper presents an implementation of GRE tunnel support on low-cost routing system on module (SoM) which is under development.
Iot oth maritime surveillance service over satellite network in equatorial environment: Analysis, design and deployment Ranko Petrovic, Dejan Simic, Zoran Cica, Dejan Drajic, Marko Nerandzic, et al. Electronics Switzerland, 2021 This paper explores the challenges and constraints when over the horizon (OTH) maritime surveillance service utilizes an Internet of Things (IoT) as its backbone. The service is based on High Frequency Surface Wave Radars (HFSWRs) and relies on a satellite communication network as its communication infrastructure in harsh environments. The complete IoT OTH maritime surveillance network is currently deployed in the Gulf of Guinea, which due to its tropical climate represents an unfavorable environment for sensors and communications. In this paper, we have examined the service performance under various meteorological conditions specific to the Gulf of Guinea. To the best of our knowledge, this is the first analysis of IoT OTH maritime surveillance service in equatorial environment. Our analysis aims to mathematically describe the impact of harsh weather conditions on the performance of the service in order to mitigate it with careful overall system design and provide constant quality of the service. Analyses presented in the paper show that average service latency is about 90 s, but it can rise to about 120 s, which is used as a key information during the sensor data fusion algorithm design. Validity of the analyses is demonstrated through high quality of service with an outage probability of just 0.1% in the driest months up to the 0.7% in the rainiest months. The work presented here can be used as a guideline for deployment of maritime surveillance service solutions in other equatorial regions. Moreover, the gained experience presented in this paper will significantly facilitate future expansions of the existing maritime surveillance network with more HFSWRs. This will be done in such a way that it will not affect the quality of service of the entire system on a large scale.
Man-In-The-Middle Attack Based on ARP Spoofing in IoT Educational Platform Ranko Petrovic, Dejan Simic, Stefan Stankovic, Miroslav Peric 2021 15th International Conference on Advanced Technologies Systems and Services in Telecommunications Telsiks 2021 Proceedings, 2021 Although the development and implementation of IoT systems is a very popular area in education, there is a perception that still not enough attention is devoted to the security of IoT systems, especially in a practical manner. This is especially important for the utilization of IoT in mission-critical applications that demand a high level of security. Accordingly, in this paper, an IoT educational platform for testing security vulnerabilities of IoT systems is presented. During the professional internship, students will get familiar, in a practical way, with the ease of address resolution protocol (ARP) spoofing attack, using the proposed educational platform. Also, students will simultaneously learn defense mechanisms.
Enhancement Algorithms for Low-Light and Low-Contrast Images Snezana Puzovic, Ranko Petrovic, Milos Pavlovic, Srdan Stankovic 2020 19th International Symposium Infoteh Jahorina Infoteh 2020 Proceedings, 2020 Images in bad weather can be degraded by scattering atmospheric particles, and suffer from low contrast and faint color. Main focus of this work is on dehazing methods that can be used for low-light and low-contrast conditions. Dehazing algorithms can be applied to low-light (night) imaging in a way that inverted night images are considered as hazy images. Different image quality metrics are used to measure quality of image enhancement algorithm. Since it is not easy to obtain original image without haze, special attention is given to the no-reference metrics that evaluate image contrast enhancement.
Designing laboratory for iot communication infrastructure environment for remote maritime surveillance in equatorial areas based on the gulf of guinea field experiences Ranko Petrovic, Dejan Simic, Dejan Drajic, Zoran Cica, Dejan Nikolic, et al. Sensors Switzerland, 2020 The steady increase of the world population and economy leads to an increase in both types and amounts of goods transported over seas, which further inevitably leads to an increase of criminal activities in the maritime arena. In order to stifle criminal activities nations are forced to develop sophisticated sensor networks. The backbone of any sensor network is a communication network which connects all sensors with the command centers, most often located hundreds of kilometers away from the sensors. In developing countries, communication networks are very often poorly developed, leaving only satellite links as somewhat reliable means of communication. Henceforth, in this paper, a laboratory for the Internet of Things (IoT) communication infrastructure environment designed to facilitate maritime sensor network design process in areas where communication network is dependent on data transfer over satellite links is presented. In order to successfully describe and develop a laboratory for IoT communication infrastructure environment, necessary data are collected during the design and deployment of a maritime surveillance network in the Gulf of Guinea. The main advantage of the proposed laboratory environment is the inclusion of satellite link simulation in the IoT laboratory environment. This feature provides an opportunity to cover a much broader scope of IoT solutions compared to other IoT laboratories.
Implementation Challenge and Analysis of Thermal Image Degradation on R-CNN Face Detection Nikola Latinović, Tijana Vuković, Ranko Petrović, Miloš Pavlović, Marko Kadijević, et al. Telfor Journal, 2020 Face detection systems with color cameras were rapidly evolving and have been well researched. In environments with good visibility they can reach excellent accuracy. But changes in illumination conditions can result in performance degradation, which is the one of the major limitations in visible light face detection systems. The solution to this problem could be in using thermal infrared cameras, since their operation doesn't depend on illumination. Recent studies have shown that deep learning methods can achieve an impressive performance on object detection tasks, and face detection in particular. The goal of this paper is to find an effective way to take advantages from thermal infrared spectra and provide an analysis of various image degradation influence on thermal face detection performance in a system based on R-CNN with special accent on implementation on a hardware platform for video signal processing that institute Vlatacom has developed, called vVSP.
