摘要:

在无线网络中,流量预测在有效规划和使用网络资源方面起着至关重要的作用。虽然有线网络中的流量预测是一个既定的领域,但缺乏对蜂窝网络中的流量分析的研究,特别是在用户级别上以内容盲的方式。在这里,我们通过设计采用统计、基于规则或深度机器学习方法的流量预测工具来解决这个问题。首先,我们提出了一个广泛的实验评估的设计工具在一个真正的交通数据集。在此分析中,不同的参数,如预测的长度,分析中使用的特征集,和数据的粒度,预测的准确性的影响进行了研究。第二,关于交通行为和其生成的应用程序之间观察到的耦合,我们扩展我们的分析产生的交通的统计数据的基础上的应用程序的盲分类的交通到达/离开。结果表明存在阈值数量的先前观察结果,超过该阈值数量,深度机器学习可以优于线性统计学习,并且在此之前,统计学习优于深度学习方法。对该阈值的进一步分析表示该阈值、未来预测的长度和使用中的特征集之间的强耦合。最后,通过一个案例研究,我们提出了如何经验延迟可以减少交通到达预测。

英文摘要:

Traffic prediction plays a vital role in efficient planning and usage of network resources in wireless networks. While traffic prediction in wired networks is an established field, there is a lack of research on the analysis of traffic in cellular networks, especially in a content-blind manner at the user level. Here, we shed light into this problem by designing traffic prediction tools that employ either statistical, rule-based, or deep machine learning methods. First, we present an extensive experimental evaluation of the designed tools over a real traffic dataset. Within this analysis, the impact of different parameters, such as length of prediction, feature set used in analyses, and granularity of data, on accuracy of prediction are investigated. Second, regarding the coupling observed between behavior of traffic and its generating application, we extend our analysis to the blind classification of applications generating the traffic based on the statistics of traffic arrival/departure. The results demonstrate presence of a threshold number of previous observations, beyond which, deep machine learning can outperform linear statistical learning, and before which, statistical learning outperforms deep learning approaches. Further analysis of this threshold value represents a strong coupling between this threshold, the length of future prediction, and the feature set in use. Finally, through a case study, we present how the experienced delay could be decreased by traffic arrival prediction.
