An Improved UGS Scheduling with QoE Metrics in WiMAX Network
Tarik Anouari, Abdelkrim Haqiq

TL;DR
This paper proposes an enhanced UGS scheduling method for WiMAX that incorporates QoE metrics, leading to improved user experience by reducing delays and packet loss, validated through NS-2 simulations.
Contribution
It introduces a novel UGS scheduling approach that integrates QoE considerations, specifically MOS, into WiMAX network management.
Findings
QoE metrics like MOS improve scheduling effectiveness.
Enhanced scheduling reduces jitter, packet loss, and delays.
Simulation confirms better user experience with proposed method.
Abstract
WiMAX (Worldwide Interoperability for Microwave Access) technology has emerged in response to the increasing demand for multimedia services in the internet broadband networks. WiMAX standard has defined five different scheduling services to meet the QoS (Quality of Service) requirement of multimedia applications and this paper investigates one specific scheduling service, i.e. UGS scheduling. In parallel, it was observed that in the difference of the traditional quality assessment approaches, nowadays, current researches are centered on the user perception of the quality, the existing scheduling approaches take into account the QoS, mobility and many other parameters, but do not consider the Quality of Experience (QoE). In order to control the packet transmission rate so as to match with the minimum subjective rate requirements of each user and therefore reduce packet loss and delays,…
