QoE

A significant increase in the number of smart devices with Wi-Fi modules and the forecast growth of data
consumption in the coming years requires the development of new methods of designing Wi-Fi networks to
improve the quality of experience for end-users. In this regard, the paper improved the conceptual model of
software-defined Wi-Fi network, which, in contrast to the known, is based on centralized control of the
selection process of access point service by using SDN controller and by monitoring the state of the network in

The article is devoted to the development of a perception quality management method in softwaredefined
networking using IBN ideology. The so-called IBN (Intent-based networking) is based on the
well-known SDN (Software-Defined Network) and represents one of the most important new features of
network infrastructure. IBN offers network administrators a simple way to express business goals, such
as providing the necessary QoE, by allowing network software to automatically achieve these QoE goals.

The problem of video streaming over LTE network is analyzed. The mathematical model of resource allocation of LTE is offered during video streaming. It provides different service schedule for heterogeneous mobile traffic. It allows assuring the demanded quality parameters for better user experience. The goal of the paper is to increase the LTE user experience delivering video content over the radio access network.
