On Dependable Architectures and Networks
|
Dependable architectures comprise of a multitude of layers of network, compute, and other system mitigation approaches. In this presentation, the basis of dependable electronics architectures and multiple aerospace and space electronic platform examples will be presented. As an example, TTEthernet and BRAIN as dependable networks and self-checking compute approaches for dependable compute building blocks are discussed.

From Cyber-Enabled Discovery and Innovation to the Science of Interaction
|
Cyber-Enabled Discovery and Innovation (CDI) was introduced in 2008 as the US National Science Foundation's cross-foundation program seeking advances that are enabled by computational means in all science and engineering fields. The program was formulated to encourage innovations in, or innovative uses of, computational models, methods, tools, concepts, and algorithms to facilitate quantum leaps across a all areas of science and engineering.
Taking CDI a step further would be to foster transdisciplinary contributions, i.e., creating entirely new fields of science and engineering. In 2008, the first year in history the Earth's human population living in cities exceeded that living elsewhere, new science and engineering is necessary to solve the myriad of interwoven, pressing issues such as energy, health, safety, and supply chain management. The shift towards a mostly urban human population can indeed be a blessing or a curse on the future of our planet, depending on how the interplay between engineering, economic, and management problems are addressed within the next decade. The "Science of Interaction" is the collection of studies in natural, engineered, and social interactions. |
After formulating CDI and Network Science and Engineering Programs at the NSF, Professor Sirin Tekinay recently assumed the position of founding Vice-Rector for Research and Technology at Ozyegin University, a brand new private university in İstanbul, Turkey. She was tenured faculty of the New Jersey Institute of Technology, at the Electrical and Computer Engineering since 1997. Before then, she worked at Bell Labs, Lucent Technologies, and NORTEL. Sirin received her Ph.D. degree from the School of Information Technology and Engineering at George Mason University. She was the recipient of NJIT's "Excellence in Graduate Teaching Award" in 2003. In 2007, she was the recipient of the NSF Director's Award for Program Management Excellence. In 2008, CDI and her entire team of a hundred members received the "Collaborative Integration Award." She initiated the pre-cursor to NSF's current Network Science and Engineering program SING -- Scientific Foundations for Internet's Next Generation. Sirin holds eight patents. She is an active member of the IEEE Communication Society.

Smart Sleeping Policies for Wireless Sensor Networks |
The nodes in a wireless sensor network typically need to operate on limited energy budgets, and may therefore be switched between active and sleep modes to conserve energy. It is clear that the performance of the sensor network could degrade due to having sleepy sensors and therefore any sleeping policy trades off performance with energy savings. Such sleeping is usually effective only if the sensor is completely turned off in the sleep mode, i.e., a sensor that is asleep cannot be communicated with or woken up prematurely. A natural way to implement the sleeping in this setting is to have the sensor enter and exit the sleep mode using a fixed or random duty cycle. This presentation will describe an alternative smart approach to sleeping that uses all available information about the state of the network to set the sleep times of the sensors. It is shown through the example of tracking that the smart approach can yield significant improvements over the duty cycle approach in the tradeoff between performance and energy savings. |

A roadmap for 3D Technologies and their Design Opportunities |
3D integration offers numerous opportunities for design, and is probably
the best hope for carrying ICs along (and even beyond) the path of
Moore's Law in the 21st century. However, many questions still need to
be answered to take advantage of 3D. First, what will become the
mainstream 3D technology? Today, many technology options are proposed,
but each having different cost, design and implications. Secondly, how
to make 3D designs reliable? Many unknowns still exist related to
thermal load, reliability and signal integrity challenges. Finally,
what about design solutions/methods and architectural modifications for
3D integration? In this talk, an attempt will be made to roadmap 3D
technologies and their design implications. |
Paul Marchal received the engineering degree and Ph.d. in electrical
engineering from the Katholieke Universiteit Leuven, Belgium in 1999 and
2005 resp. He holds now a position as principal scientist at IMEC,
Leuven. Dr. Marchal's research interests are in all aspects of design of
digital systems, with special emphasis on 3D design and technology-aware
design techniques for low-power systems. |

A System Theoretic Approach to Bandwidth Estimation
|
Much research has been dedicated to methods that estimate the available bandwidth in a network from traffic measurements, yet little progress has been made on achieving a foundational understanding of the bandwidth estimation problem. In this talk, we develop a min-plus system theoretic formulation of bandwidth estimation. We show that the problem as well as previously proposed solutions can be concisely described and derived using min-plus system theory, thus establishing the existence of a strong link between network calculus and network probing methods. We relate difficulties in network probing to potential non-linearities of the underlying systems, and provide a justification for the distinctive treatment of FIFO scheduling in network probing. Experiments on an Emulab testbed are used to evaluate the theoretical concepts in actual implementations of probing schemes.
This talk presents joint work with Markus Fidler (TU Darmstadt) and Shahrokh Valaee (U. Toronto). |
Jorg Liebeherr received the Ph.D. degree in Computer Science from the Georgia Institute of Technology in 1991.

Pervasive Broadband Wireless Access |
Broadband wireless access is the third wireless revolution, after
cellphones (1990s) and Wi-Fi (2000s). It is viewed by many carriers and
cable operators as a “disruptive” technology and rightly so. The broadcast
nature of wireless transmission offers ubiquity and immediate access for
both fixed and mobile users, clearly a vital element of next-generation
quadruple play (i.e., voice, video, data, and mobility) services. Unlike
wired access (copper, coax, fiber), a large portion of the deployment
costs is incurred only when a subscriber signs up for service. An
increasing number of municipal governments around the world are financing
the deployment of multihop wireless networks with the overall aim of
providing ubiquitous Internet access and enhanced public services. This
talk will provide a comparative assessment of the key standards and
technologies underpinning promising broadband wireless access solutions.
Key standards include 802.16 (Wi-Max), long-range/multihop 802.11 (Wi-Fi),
wireless DOCSIS, 3G/4G/LTE, mobile digital TV broadcast (DVB-H, MediaFLO),
802.20 (mobile broadband), 802.21 (media independent handoff and
interoperability), and the emerging 802.22 (wireless regional area
networks) standard. Key technologies include licensed and unlicensed
spectrum consideration; reliable physical layer transmission using
multiple antennas; wireless access topologies; wireless multimedia
services; mobility; cognitive radio technologies; advanced wireless
security; fixed-mobile convergence.

Implications of Emerging Optical Technologies on Future Internet |
In this talk, we will articulate research opportunities and challenges in
terms of Future Internet design, as influenced by emerging optical

narrowly-focused research. Instead, the talk will be about the broad
perspective of how these technologies -- and their expected rapid
development -- might affect the larger overall network architecture, and
vice versa. |
