Research interests: architecture of multiprocessor computing systems, formal models of parallel computing, methods and tools for specification and verification of program behavior, modeling, analysis of functioning, synthesis and adaptation of multiprocessor computing systems, real-time systems.

Currently the computing infrastructure is moving from the “create it by yourself” concept to the “get as a service” concept. The former one assume you don't need to buy and develop by your own computing infrastructure, rent channels to connect to a public network, or hire expensive specialists for system and network administration. In the new paradigm, resources and services can be requested and received as you need. The emergence of new technologies for virtualization of computing resources, software-defined networks and virtualization of network functions have opened up new opportunities for the development of data processing centers (DС). Now it's not so important how many servers and racks are in DC. What is really important are the latency of request processing and how efficiently we can map virtual resources to physical ones in DC. The presentation considers the functional architecture of the NPC, the role and place of multi-agent optimization methods in managing data flows and distributing the computational load in the NPC, presents a list and statements of the main tasks.

Many emerging applications such as Virtual Reality, online gaming, and Factory Automation require low latencies and consistently high data rates. This problem becomes a challenge in Wi-Fi networks because of random access and interference. Nevertheless, the developers of Wi-Fi 8 are going to solve it and provide the required quality of service in the vast range of scenarios. In the talk, we will discuss possible approaches for that and open issues.

The report contains an analytical overview of modern communication systems that provide voice transmission and high-speed digital information (photos, videos, file sharing, etc.) between mobile subscribers in the UHF frequency range.
The main attention is paid to the implementation of the following modern trends in the development of professional UHF radio equipment:
- the use of modern types of modulation and error-correcting coding in adaptive modes of operation;
- structure of UHF transceivers based on "software-defined radio" (SDR) technology;
- organization of decentralized self-organizing mesh radio networks, where each terminal simultaneously performs the functions of a transceiver, repeater and router;
- ensuring the required reliability of information exchange in a complex interference environment, including when exposed to electronic warfare.

Autonomous navigation systems for tethered unmanned aerial vehicles
Vytovtov Konstantin Anatolyevich, Doctor of Technical Sciences, Associate Professor, Leading Researcher at the IPU RAS. Graduated from the Dnepropetrovsk Higher Anti-Aircraft Missile Command School of Air Defense in 1988. In 2003 he defended his dissertation for the degree of candidate of physical and mathematical sciences in the specialty “Radiophysics”. In 2020, he defended his dissertation for the degree of Doctor of Technical Sciences in the specialty “Mathematical modeling, numerical methods, software packages.”
The development of unmanned aircraft has been progressing at a rapid pace in recent years. Today, the development of autonomous navigation systems in the absence of GPS and GLONAS signals is relevant. Among the most common methods of autonomous navigation are acoustic, optical, methods using machine vision, and magnetic.
Employees of the IPU RAS have proposed a hybrid system for local navigation of a tethered high-altitude platform, which includes a radar subsystem and a subsystem based on computer vision. The radar subsystem is designed for the 60 GHz range, providing stable tracking of a high-altitude platform and high noise immunity

Resource alloction for THZ drone communications with realistic antennas and mobility patterns
Özgür Gürbüz received her B.S. and M.S degrees in Electrical and Electronics Engineering at Middle East Technical University, in 1992 and 1995, respectively. She received her Ph.D. degree in Electrical and Computer Engineering from Georgia Institute of Technology in 2000. From 2000 until 2002 she worked as a researcher and systems/algorithms engineer for Cisco Systems, in Wireless Access and Wireless Networking Business Units. As of September 2002, Dr. Gurbuz joined the Faculty of Engineering and Natural Sciences at Sabanci University, where she is now a Professor. Her research interests are in the field of wireless communications and networks, specifically design of link and higher layer network algorithms/protocols for emerging physical layer techniques including full-duplex communication, cooperative communication, MIMO, smart antennas. Recently, she has been working on full-duplex communication, digital self-interference cancellation and applications of machine learning in wireless communications/networks and THz communications. She is a member of IEEE and IEEE Communications Society.
This work considers Terahertz (THz) drone communications by applying various resource allocation schemes with practical THz antennas within the frequency range of 0.75-4.4 THz under realistic mobility and misalignment scenarios, ensuring a more accurate representation of real-world conditions. Through numerical simulations, we unveil the real capacity achievable within the realm of Tbps up to 100 meters range, when drones are in motion and subject to alignment and moderate misalignment. However, when exposed to actual mobility traces, the performance of all resource allocation schemes experiences a significant drop, sometimes up to six orders of magnitude, due to occasional reverse orientations of antennas. Consequently, the need arises for active beam control solutions to maintain the performance of THz drone networks. These findings highlight both the significant strides made in THz technology and the remaining challenges for the integration of THz band drones into the fabric of 6G networks.
