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
real-time by software to implement its own solutions to initiate the handover. The method of handover
initiation in the software-defined wireless Wi-Fi network is developed. This method to make a control decision
to select the access point of service, is based on an integral criterion of QoE generated from measurements in
real-time parameters, signal strength, throughput, data loss and delay in the Wi-Fi network, which improved
the QoE by end-users. The use of the developed scientific-applied solutions for the handover procedure based
on the QoE criterion will allow to apply in practice the research organizations, companies, mobile operators to
improve QoE.
