Duy-huy Nguyen, Hang Nguyen, E� Ric Renault . A new Channel- and QoS-Aware scheduling Scheme for Real-time Services in LTE Network. International Journal of Applied Information Systems. 11, 4 ( Sep 2016), 1-8. DOI=10.5120/ijais2016451601
Abstract
This paper proposes a new scheduling scheme which is based on Channel- and QoS-Aware for real-time traffics in LTE downlink direction. The real-time services (VoIP, Video, etc. ) are very sensitive to network impairments such as delay, packet loss, jitter, etc. The proposed scheduling scheme considers Maximum Queue Size (MQS) as an essential factor for the priority metric and the combination of well-known M-LWDF-based algorithms such as M-LWDF, VT-MLWDF and Queue-HOL-MLWDF. The simulation results show that the proposed scheme has the performance which not only satisfies QoS requirements of realtime services but also outperforms the M-LWDF, VT-MLWDF and Queue-HOL-MLWDF schedulers in terms of Packet Loss Rate (PLR), cell throughput, Fairness Index (FI) and Spectral Efficiency (SE), especially for Video flow. The proposed scheduler also significantly improves the delay in comparison with the VT-MLWDF and Queue-HOL-MLWDF schedulers ones for both VoIP and Video flows. The performance evaluation is compared in terms of Delay, PLR, Throughput, FI and SE for MLWDF, VT-MLWDF, Queue-HOL-MLWDF and the proposed schedulers.
