Avaliação da Qualidade de Vídeo e VoIP em Sistema LTE com diferentes Algoritmos de Escalonamento utilizando Métricas de QoS


This work presents a comparative study of Quality of Service (QoS) metrics in different packet schedulers, of the LTE (Long Term Evolution) System, proposed for 3GPP (3rd Generation Partnership Project), namely PF (Proportional Fair), M-LWDF (Maximum Largest Weighted Delay First) and EXP- PF (Exponential Proportional Fair). The performance evaluation from the metrics used in this study are the following: Packet Loss and Throughput. Simulation results have shown that the M- LWDF scheduler is able to provide QoS for a realistic scenario in a LTE network.
