瑞典计算机科学学院(SICS-Swedish Institute of Computer Science) 的Anders Lindgren和Fehmi Ben Abdesslem博士应高等智能与网络服务111引智基地的邀请，将于10月22日来北邮作学术报告。欢迎有兴趣的师生踊跃参与。
题目：Keeping it real – The importance of experiencing and understanding real mobile network environments
Dr. Anders Lindgren is a senior researcher at SICS Swedish ICT and an adjunct lecturer at Luleå University of Technology. He received his Ph.D. from Luleå University of Technology in 2006, and worked as a postdoctoral researcher at University College London and University of Cambridge. His research interests include opportunistic and information-centric networking, communication and computation in challenged environments, efficient IoT, and big data analytics for mobile networks.
Over the past decade, mobile networking has seen an explosive growth, in particular with the introduction of smart-phones. This is creating incredible new opportunities for users to stay connected and utilize our connected society in their daily life. It does however also come with problems as operator networks become overloaded, without operators necessarily understanding exactly how their customers will use the network. Furthermore, it also comes with the risk of further increasing the digital divide between the rich and poor parts of the world, as some societal services will only be available to those with access to connectivity.
In this talk, I will focus on the importance of keeping it real, and not solely design networks based on synthetic models and simulations. Through examples from real deployments, field experiences, and network measurements, I will show some examples of what users really want in different scenarios and this can be realized even in challenged scenarios.
Mobile networks span a very wide range of scenarios and use cases, and I will focus at some particular scenarios at the extreme ends of this spectrum. I will explain how they differ and are similar to more common situations, and discuss why it is important to understand the specific characteristics of these situations and how they affect network design. In particular, I will look at the following two scenarios based on previous personal experience:
– What can be done for users that do not have access to reliable (or low-capacity) communication infrastructure? I will explain some existing technical solutions for providing network access to people living outside the rich and well-connected parts of the world, and will, most importantly, explain the importance of properly understanding the target user groups in order to create good network designs.
题目：Big Data in Computer Networks – From Mobile Devices to The Internet of Things
主讲人：Fehmi Ben Abdesslem研究员
Dr Fehmi Ben Abdesslem received his M.Sc and PhD from the University of Paris 6 in 2008, before working as a research associate at the University of St Andrews, and at the University of Cambridge. He has then been awarded a Marie-Curie research fellowship from the European Commission (ERCIM) to join SICS, and is now a permanent Senior Research Scientist at the Decisions Networks and Analytics laboratory.
Big data is nowadays a common term regularly appearing in the news as part of our every day life. Large amounts of data are constantly collected, stored and analysed. In this presentation, we will first explain and discuss this trend before highlighting the research challenges in computers networks. We will then describe an example of big dataset collected from mobile phones, and show the applications of analysing such datasets. Finally, we will provide a short introduction about the potential benefits of the big data generated by the Internet of things.
