基于线性规划的移动视频流的预期无线资源管理

Anticipatory Radio Resource Management for Mobile Video Streaming with Linear Programming

Dimitrios Tsilimantos, Amaya Nogales-Gómez, Stefan Valentin

摘要:

在预期组网中,信道预测被用来提高通信性能。本文介绍了一种新的方法,分配资源的视频流业务,同时占服务质量。所提出的方法是基于将用户的本地播放缓冲器的模型集成到无线电接入网络中。这个模型的线性允许制定一个线性规划问题,优化分配的资源和媒体流的停滞时间之间的权衡。我们的模拟结果表明,在一个简单的,但有代表性的情况下,预期优化的全部力量。与瞬时自适应相比,我们的预期解决方案在可行的计算时间内表现出令人印象深刻的频谱效率和停滞持续时间的增益,同时对预测误差具有鲁棒性。

英文摘要:

In anticipatory networking, channel prediction is used to improve communication performance. This paper describes a new approach for allocating resources to video streaming traffic while accounting for quality of service. The proposed method is based on integrating a model of the user's local play-out buffer into the radio access network. The linearity of this model allows to formulate a Linear Programming problem that optimizes the trade-off between the allocated resources and the stalling time of the media stream. Our simulation results demonstrate the full power of anticipatory optimization in a simple, yet representative, scenario. Compared to instantaneous adaptation, our anticipatory solution shows impressive gains in spectral efficiency and stalling duration at feasible computation time while being robust against prediction errors.
