A SURVEY ON MACHINE LEARNING ALGORITHMS FOR SOFTWARE-DEFINED NETWORKS
Z. Kanivets, A. Vybornova

 Read

Abstract: With the advent of the concept of Software-Defined Networks with a centralized control plane, it became possible to collect a huge amount of information about the network, for example, network topology, network congestion, the state of network devices. This data can be used to train machine learning algorithms. Moreover, these algorithms can be applied for completely different purposes, such as traffic classification, quality of service, optimization of traffic transmission routes, resource management, and security. Research subject of this article consist on the different aspects of SDN operating that can be optimized with ML. Research method is an analysis of the literature on the subject. Core results are analysis and classification of the areas and methods of the ML algorithms implementation for the SDN. Practical relevance of the work is that the results can be used for optimization of different SDN characteristics.

Keywords: software defined networks, machine learning algorithms.

AN ENERGY-EFFICIENT ALGORITHM FOR SERVICE MIGRATION IN UAV NETWORKS
V. Kovalenko, A. Rodakov, A. S. Muthanna

Abstract: Research subject is developing an algorithm (sequence of actions) performed when the charge of the internal battery of the UAV is reduced to migrate services from one UAV to another and move the UAV to the charging zones of the internal battery. Research method. Studying the ways of organizing the architecture of networks with UAVs, UAV applications; consideration of various ways to implement an SDN controller: at a ground Base Station, on a fixed balloon, at the head node, on all UAVs of one cluster and implementation using several controllers of different levels; identification of the main advantages from the use of the SDN concept in UAV systems. Core results. 4 ways of using UAVs are described in detail, as well as the main functions that should be implemented in the UAV cluster to perform tasks in all 4 areas of application, as well as to implement the SDN concept in the flying segment; possible ways of implementing the SDN controller in networks with UAVs are considered; the main advantages obtained in UAV systems when implementing the SDN concept are presented; theoretically substantiated the need to migrate services from one UAV to another and the inexpediency of implementing all functions on each UAV: the charge of the internal UAV battery is limited, and the more services or functions are implemented on the UAV, the more power consumption; an algorithm (sequence of actions) is proposed that will be performed when the internal battery of the UAV is discharged. This algorithm includes the following processes: the process of determining the UAV for subsequent service migration, the process of determining the service migration route, as well as the processes for sending the UAV to recharge the built-in battery, and upon returning the UAV to the state of performing the tasks assigned to it. Practical relevance. The article contains a detailed description of the ways of organizing the UAV architecture, the main areas of UAV application, as well as the advantages obtained in UAV systems when implementing the SDN concept. Also useful is information on possible ways to implement the SDN controller. The presented algorithm (sequence of actions) for the implementation of the migration of services and the movement of the UAV to the recharge zones in the future can be applied in practice when the charge of the built-in UAV battery is reduced to a certain level.

Keywords: UAV, UAV networks, ground and flying segment, SDN, SDN controller and switch, head node, service migration, ground Base Stations, stationary balloons.

OVERVIEW OF EQUIPMENT FOR CAPTURING 3D IMAGES WITH SUBSEQUENT TRANSMISSION THROUGH A COMMUNICATION NETWORK
B. Pankov, M. Makolkina
Abstract: The relatively recent advent of the publicly available consumer RGB-D sensors has enabled a wide range of functionality to interact with 3D technology. For example, devices such as Microsoft Kinect v1, Microsoft Kinect v2, and Intel Realsense F200 are currently available RGB-D sensors using Structured light and Time of Flight technologies for getting information about pixel depth. The article contains an extensive comparison of RGB-D devices in terms of the resolution of RGB and Depth cameras, latency (the time required to build a depth map and its processing), and also compares viewing angles, required USB interfaces, sensor sizes, etc. The main goal of the article is to provide a complete and visual comparison of devices that can potentially be used to capture three-dimensional images with their subsequent transmission by communication networks.
Keywords: transmission of three-dimensional images, augmented reality, communication networks 2030, holography, RGB-D, Intel Realsense F200, Kinect v1 / v2, 3D.
