    LTE resource-aware dynamic adaptive wireless multimedia streaming system by Bingjiang CAI

    Published 2021-01-01
    “…The quality of user experience in adaptive video streaming, to a large extent, depends on the accuracy of the end-to-end bandwidth estimation.However, bandwidth estimation is very challenging in highly dynamic LTE network.LTE resource-aware dynamic adaptive wireless multimedia streaming system was designed and implemented in which the LTE resource block monitor module keeps monitoring the cell-wide physical layer resource utility.The rate scaling mechanism mapped the throughput to an estimation of available bandwidth and the rate adaption algorithm selected the most appropriate representation combining current available bandwidth with buffer state and played a trade-off between video quality and the risk of stalling.The experimental results on the prototype system show that comparing with the two baseline algorithms, the proposed system achieves the highest average video bitrate while maintaining a fairly low stalling rate, and effectively enhances the quality of experience.…”
