论文摘要
移动体验如何比较德国和尼日利亚之间？当前没有公共数据或测试床可以为此问题提供答案。这是因为部署和维护此类测试床既具有挑战性又昂贵。为了填补这一空白，本文提出了一种名为“ Amigo”的新型测试床设计，该设计依赖于携带手机的旅行者充当有利位置并收集有关移动网络性能的数据。 “ Amigo”设计具有三个关键优势：它很容易部署，具有现实的用户移动性并在真实的Android设备上运行。我们进一步开发了一套测量工具，用于“ Amigo”进行网络测量，例如ping，speedtests和网页负载。我们利用这些工具在一个月内通过涉及31名学生的“ Amigo”部署来衡量五大洲的24个移动网络的性能。我们发现，有50％的网络面临40-70％的数据率，只有20％的网络获得低潜伏期，并且在亚洲，中/南美和非洲的网络的CDN下载时间明显高于欧洲。大多数新闻网站加载缓慢，而YouTube表现良好。我们制作了测试床和测量工具开源。
How does the mobile experience compare between Germany and Nigeria? There is currently no public data or test-bed to provide an answer to this question. This is because deploying and maintaining such test-bed can be both challenging and expensive. To fill this gap, this paper proposes a novel test-bed design called "AmiGo", which relies on travelers carrying mobile phones to act as vantage points and collect data on mobile network performance. The "AmiGo" design has three key advantages: it is easy to deploy, has realistic user mobility, and runs on real Android devices. We further developed a suite of measurement tools for "AmiGo" to perform network measurements, e.g., pings, speedtests, and webpage loads. We leverage these tools to measure the performance of 24 mobile networks across five continents over a month via an "AmiGo" deployment involving 31 students. We find that 50% of networks face a 40-70% chance of providing low data rates, only 20% achieve low latencies, and networks in Asia, Central/South America, and Africa have significantly higher CDN download times than in Europe. Most news websites load slowly, while YouTube performs well. We made both test-bed and measurement tools open source.
