Intelligent Adaptive Management in Local Wireless Networking

Prof. Dr. Adam Wolisz

Technische Universität Berlin


Wireless technologies play a constantly increasing role also in the local connectivity. They differ from their wired counterparts by far not only in less reliable (and variable) medium and, thus, MAC protocols. Due to limitations in frequency availability, the need for coexistence of different networks (both different technologies and different instances of the same technology managed autonomously by different owners) becomes more and more recognized. The talk will address the questions of adaptive management in such networks.


Adam Wolisz received the Diploma degree in 1972, the Ph.D. degree in 1976, and the Habil. degree in 1983, all from the Silesian University of Technology, Gliwice, Poland. He worked several years with the Deptartment of Complex Automation Systems (later Institute of Theoretical and Applied Informatics of the Polish Academy of Sciences) in Gliwice, Poland and GMED Fokus in Berlin leading activities in computer networks and distributed system design and evaluation.

He joined Technische Universität Berlin, Berlin, Germany, in 1993, where he is currently a Chaired Professor in Telecommunication Networks and an Executive Director of the Institute for Telecommunication Systems. He is also an Adjunct Professor with the Department of Electrical Engineering and Computer Science, University of California at Berkeley, Berkeley, Calif., USA. His current research interests include architectures and protocols of communication networks, wireless/mobile networking, and sensor networks.

30 years of Internet Security and the winner is ...

Dr. Marc Dacier

Principal Scientist
Cybersecurity Group
Qatar Computing Research Institute & HBKU
Doha, Qatar


Thirty years ago, Brian Reid published an article in the Software Engineering journal entitled "Lessons from the Unix Break-ins at Stanford" [1]. Two years later, we experienced the first major outbreak of the Internet with the so-called Morris worm that was using vulnerabilities that had been publicly reported but not fixed. These were the early days. Such errors were understandable. But have things really changed? In this talk, we will look at some of the past issues that we had to deal with, the lessons learned and, more importantly, the still ongoing plagues that we deal with on a daily basis. The talk will also look at emerging technologies from a security point of view. Are they going to help us, with respect to security issues, or at the contrary are they going to make things worse?

CloudNA Workshop

Cloud Native Application Development

Vijay Rajagopal

Advisory Platform Architect
MEA | Pivotal
Dubai, UAE


In the past decade, while enterprises across the world were busy adopting technology to support their business, startups such as Uber, Airbnb, Nest were disrupting traditional industries. Ever wondered how startups with limited resources could challenge traditional enterprises in their own business? The answer is taking a Software-first approach where business models are defined by software and not supported by software. This talk will discuss the emerging trends in software development that are collectively called as Cloud Native Computing Approach which allows companies to turn ideas to reality in days or weeks rather than months.


Vijay Rajagopal is an advisory consultant at Pivotal helping Enterprises to transform their software development culture and to help them adopt a silicon valley mindset. He helps customers adopt a Cloud Native approach for software development and thereby become a software-first business. Vijay started his career as a Technical Consultant with Oracle in 2003 and worked with Oracle for 10 years on various large scale implementations of ERP, CRM, SOA and Big Data technologies for a number of large enterprises in EMEA. He then spent couple of years in Software AG specializing in SOA, BPM and Big Data technologies and finally joined Pivotal to focus on modern software development.

ON-MOVE Workshop

Optimizing HTTP-Based Adaptive Streaming in Vehicular Environment using Markov Decision Process

Prof. Salil Kanhere

Associate Professor
School of Computer Science and Engineering
The University of New South Wales


Hypertext transfer protocol (HTTP) is the fundamental mechanics supporting web browsing on the Internet. An HTTP server stores large volumes of contents and delivers specific pieces to the clients when requested. There is a recent move to use HTTP for video streaming as well, which promises seamless integration of video delivery to existing HTTP-based server platforms. This is achieved by segmenting the video into many small chunks and storing these chunks as separate files on the server. For adaptive streaming, the server stores different quality versions of the same chunk in different files to allow real-time quality adaptation of the video due to network bandwidth variation experienced by a client. For each chunk of the video, which quality version to download, therefore, becomes a major decision-making challenge for the streaming client, especially in vehicular environment with significant uncertainty in mobile bandwidth. In this talk, we demonstrate that for such decision making, Markov decision process (MDP) is superior to previously proposed non-MDP solutions. Using publicly available video and bandwidth datasets, we show that MDP achieves up to 15x reduction in playback deadline miss compared to a well-known non-MDP solution when the MDP has the prior knowledge of the bandwidth model. We also consider a model-free MDP implementation that uses Q-learning to gradually learn the optimal decisions by continuously observing the outcome of its decision making. We find that MDP with Q-learning significantly outperforms MDP that uses bandwidth models.

Big Sensed Data in the Internet of Things

Prof. Hossam Hassanein

Queens University
Kingston, Ontario, Canada


The Internet of Things (IoT) is opening new horizons in systems intelligence, where physical objects (embedded with sensory, identification and networking capabilities) can interact with other objects through the global infrastructure of wireless/wired Internet. These systems can be monitored and controlled by filtering and processing collected data. Such intelligent design will naturally result is efficient and cost effective systems. Several architectures are being built to implement IoT from two different perspectives. The rise of ad hoc sensors, and new manifestations of sensing systems within the Internet of Things resulted in a tide of sensed data that is potentially drowning our communication resources. In this talk I overview the evolution of sensing systems as they contributed to Big Data, and outline the rising challenges in both communicating and understanding this data. I argue that a solution lies not in sensing systems alone, but in the expedited funneling and processing of data as we attempt to prune the unnecessary, and make sense of the valuable. The quest for energy efficiency that dominated Sensor Networks for so long is now matched with a more pressing demand for ubiquity and real-time latency.

Coordinate Systems for Complex Large-scale Sensor Networks

Prof. Anura Jayasumana

Colorado State University
Fort Collins, Colorado, USA


Large networks of inexpensive devices such as sensors, actuators and smart RFIDs deployed over complex 2D and 3D physical spaces will be an integral part of the emerging Internet of Things. Networking operations such as self-organization, localization and routing depend on some coordinate system. While geographic coordinates fit well with our intuitions into physical spaces, their use is not feasible in harsh environments and in complex deployments. Virtual coordinate systems are able to better capture the network topology and thus provide a more natural network representation. Yet their theoretical foundations are not well developed and relating them to physical network characteristics is difficult. Derivatives of virtual coordinates, such as topology coordinates and directional virtual coordinates, mimic geographic coordinates but without the need for distance measurements. Using the theory of low-rank matrix completion, now it is possible to extract topology preserving maps even with partial virtual coordinate information or random pairwise distances. We propose a coordinate based paradigm that facilitates seamless integration of geographic and virtual coordinate information. The approach functions even with incomplete information, thus facilitating evolving systems whose performance improve over time as new information becomes available. A self-learning algorithm is presented for individual nodes to achieve network awareness, which we argue is a key step toward developing massive evolving int elligent sensor networks mimicking natural systems that get better and smarter over time.

WNM Workshop

YouTube Popularity Dynamics and Third-party Authentication

Dr. Niklas Carlsson

Associate Professor (Docent+universitetslektor)
Dept. of Computer & Information Science
Linköping University
Linköping, Sweden


This talk will present some of our measurement-based work on video popularity dynamics and third-party authentication. Video dissemination through sites such as YouTube can have widespread impacts on opinions, thoughts, and cultures. However, not all videos will reach the same popularity and have the same impact. In this talk, we first present some of our work on modeling video popularity dynamics and assess, both qualitatively and quantitatively, the impacts of various content-agnostic factors on video popularity. Second, we present an analysis of the third-party authentication landscape, including a comparison with the third-party content delivery landscape, a longitudinal study of current trends, as well as an evaluation of cross-site information leakages and privacy risks associated with these increasingly used services. If time permits, we may also discuss current personalization trends, and briefly introduce our novel design and implementation of an interactive branched video player solution that allows users to select their own paths through a branched multi-path video, while ensuring seamless playback even when the users defer their branch path choices to the last possible moment.


Niklas Carlsson is an Associate Professor at Linköping University, Sweden. He received his M.Sc. degree in Engineering Physics from Umeå University, Sweden, and his Ph.D. in Computer Science from the University of Saskatchewan, Canada.
