论文摘要
随着移动通信的快速发展,多媒体服务在过去几年中经历了爆炸性的增长。消费和从云计算(CC)消耗和生产这些服务的移动用户数量的大量可以超过可用的带宽容量。 FOG计算(FG)将自己作为解决方案和其他问题的解决方案。随着网络延迟的减少,实时应用程序受益于改善响应时间和更大的整体用户体验。考虑到这一点,这项工作的主要目标是三倍。首先,提出了一种基于云消毒计算(CFC)的环境的方法。其次,它是基于自回旋积分移动平均线(ARIMA)和长期记忆(LSTM)设计的两个模型。目的是预测需求并保留节点的存储能力,以改善多媒体服务的定位。后来,提出了一种了解数据流量预测的多媒体服务放置问题的算法。目的是选择最小数量的节点,以考虑其硬件能力提供多媒体服务,以使服务所有需求的延迟被最小化。带有实际数据的评估表明,所提出的算法将节点更接近用户满足其需求。这样可以改善提供给最终用户的服务,并增强部署的网络以减轻提供商的成本。此外,减少对云的需求,允许关闭数据中心中的服务器不要浪费能量
With the rapid development of mobile communication, multimedia services have experienced explosive growth in the last few years. The high quantity of mobile users, both consuming and producing these services to and from the Cloud Computing (CC), can outpace the available bandwidth capacity. Fog Computing (FG) presents itself as a solution to improve on this and other issues. With a reduction in network latency, real-time applications benefit from improved response time and greater overall user experience. Taking this into account, the main goal of this work is threefold. Firstly, it is proposed a method to build an environment based on Cloud-Fog Computing (CFC). Secondly, it is designed two models based on Autoregressive Integrated Moving Average (ARIMA) and Long Short-Term Memory (LSTM). The goal is to predict demand and reserve the nodes' storage capacity to improve the positioning of multimedia services. Later, an algorithm for the multimedia service placement problem which is aware of data traffic prediction is proposed. The goal is to select the minimum number of nodes, considering their hardware capacities for providing multimedia services in such a way that the latency for servicing all the demands is minimized. An evaluation with actual data showed that the proposed algorithm selects the nodes closer to the user to meet their demands. This improves the services delivered to end-users and enhances the deployed network to mitigate provider costs. Moreover, reduce the demand to Cloud allowing turning off servers in the data center not to waste energy
