50 Billion M2M Devices in 5G?

Speaker: Mischa Dohler, Centre for Telecom Research
Time: 11:00 am - 12:00 pm, Aug 13, 2014
Location: 2MTC, 10th floor, Room 10.099, Brooklyn, NY

A hyper-connected cyber-physical world, by some touted as the 4th Industrial Revolution with unprecedented economic and social opportunities, will heavily rely on the machine-to-machine (M2M) paradigm. Previous designs, which made us believe that low power radios or provisioning of horizontal platforms are driving factors, failed. This talk thus revisits the lessons we learned and how we apply them to invoke architectural and protocol changes to emerging 5G design efforts so that machine type communications (MTC) become a solid constituent of the future IoT connectivity landscape. The talk is based on first-hand experience gained from ETSI M2M, IETF ROLL and other standardization efforts; as well as the successful creation of the pioneering M2M company Worldsensing.

About the Speaker: Mischa Dohler is full Professor in Wireless Communications at King's College London, Head of the Centre for Telecommunications Research, co-founder and member of the Board of Directors of the smart city pioneer Worldsensing, Fellow and Distinguished Lecturer of the IEEE, and Editor-in-Chief of the Transactions on Emerging Telecommunications Technologies.

Space-Time Coding in Aeronautical Telemetry

Speaker: Michael Rice, Brigham Young University
Time: 11:00 am - 12:00 pm, Sep 11, 2014
Location: 2MTC, 10th floor, Room 10.099, Brooklyn, NY

In air-to-ground radio links, transmission can sometimes be blocked when the aircraft maneuvers place the fuselage between the airborne transmit antenna and the ground-based receive antenna. This problem is usually overcome by using two transmit antennas on the aircraft (say, on the top and bottom). But this creates a new problem: when the same signal is transmitted from both antennas, the communications link suffers from self-interference caused by destructive interference between the two copies of the transmitted radio signal. This talk describes a solution to this problem based on Alamouti space-time block code to overcome the problem. The organization of the talk is as follows: the basic principles of the space-time block code are presented, experimental hardware realizations of the transmitter and receiver are described, and the results of flight tests at Edwards AFB, California are summarized.

Real-time knowledge discovery and decision making from Big Data

Speaker: Jie Xu, University of California, Los Angeles
Time: 1:30 pm - 2:30 pm, Sep 11, 2014
Location: 2MTC, 9th floor, Room 9.101, Brooklyn, NY

As the world becomes ever more connected and instrumented, decision-makers have ever more rapid access to ever changing and growing streams of data – but this makes the decision-maker’s problems ever more complex as well, because it is impossible to learn everything in the time frame in which decisions must be made. What the decision-maker must do, therefore, is to discover in real time what is relevant in the enormous stream of data and use the relevant information to make good decisions. This talk presents a systematic framework and associated algorithms that enable a decision-maker to do this, and shows how to use them in real-time traffic prediction as an application scenario. With the vast availability of traffic sensors from which traffic information can be derived in real-time, a lot of research effort has been devoted to developing traffic prediction techniques, which in turn improve route navigation, traffic regulation, urban area planning and etc. One key challenge in traffic prediction is how much to rely on prediction models that are constructed using historical data in real-time traffic situations. Our decision framework learns from the current traffic situation in real-time and predicts the future traffic by matching the current situation to the most effective prediction model. When the traffic prediction involves multiple distributed learners but only the feedback about the overall effect of their decisions is available, we also propose fast learning algorithms by exploiting the informativeness of the global feedback. The algorithms we propose yield strong performance guarantees for both the long run and the short run. The applications are numerous besides traffic prediction, including patient monitoring, surveillance, social networks etc.

Advanced Game Theoretical Models and Applications in Networks

Speaker: Yezekael Hayel, University of Avignon
Time: 11:00 am - 12:00 pm, Sep 25, 2014
Location: 2MTC, 10th floor, Room 10.099, Brooklyn, NY

Abstract: New communication networks are more and more complex (heterogeneous, dynamic, etc) and mainly more decentralized. Performances of those networks are difficult to determine, even more when the network is composed of non-cooperative agents. Examples of such networks are: new wireless networks like « self-organized networks », social networks, transportation networks, etc. In the last ten years, Game Theory has become one of the more suitable mathematical tools to study and to optimize those decentralized complex networks. In this presentation, I will expose some works related to advanced game theoretical models and applications to decentralized resource allocation problems in networks. In fact, some particular networks assume strong properties about the interactions between the agents and on the network characteristics. Hierarchical games assume a multi-level structure between the decision makers. Important results can be obtained using this type of non-cooperative game for new wireless networks like Cognitive Radio Networks, based on opportunistic spectrum usage. Evolutionary games, inspired by Darwin's evolution principle, are able to propose models for complex networks with large number of players. Particularly, those models take into consideration robustness of the equilibrium against deviations of a fraction of individuals and also can serve as basement to build learning procedures that converge to equilibrium. Finally, routing games, initiated in transportation networks, propose facilities to model management problems in networks dealing with content distribution and to understand how pricing mechanisms can be used to control/to influence usage in different types of networks (social networks, transportation, content, etc).

About the Speaker: Yezekael Hayel is an Assistant Professor with tenure position at University of Avignon in France.

He had a Ph.D. in Computer Science from University of Rennes 1 and INRIA in 2005 on Network pricing. His research interests include performance evaluation of networks based on game theoretic and queueing models. He looks at applications in communication and transportation networks like: wireless flexible networks, bio-inspired and self-organizing networks, economics models of the internet and yield management. Recently, his application domains enlarge to transportation networks, social networks and complex networks.

Information Theory: Old and New--A Personal View

Speaker: Shlomo Shamai, Israel Institute of Technology
Time: 11:00 am - 12:00 pm, Oct 23, 2014
Location: Pfizer Auditorium, Bern Dibner Library of Science & Technology, 5 MetroTech Center, Brooklyn, NY

Part of Jack Keil Wolf Lecture Series

The presentation starts by demonstrating in a descriptive way the origin of information theory in Shannon’s 1948 monumental work, and pointing some interdisciplinary aspects within general areas of electrical engineering and beyond. We discuss a change of paradigms in information theory from being a pure mathematical theory of communications to a theory with widescope direct practical implications and applications. To demonstrate the rich aspects of the problems considered and their implications as well as some inter disciplinary connections, we focus on a simple matrix based linear additive Gaussian model. We elaborate on the information-estimation intimate connection, mentioning its impact on non-linear filtering and on recent views of efficient coding in single and multi-terminal channels. Possible extensions to general channels and a short outlook conclude the presentation.
