Optical Flow Switching - a faster, greener and more frugal network transport

Present-day networks are being challenged by dramatic increases in bandwidth demand of emerging applications. We will explore a new network architecture, ”optical flow switching”, that will enable significant data rate growth, power-efficiency and cost-effective scalability of next-generation networks. In particular, we will address the most important remaining open problem of an implementable optical flow switching architecture: the scalable control plane.

-The conundrum of channel access-

A basic question in wireless networks is whether the users who share a common channel should schedule their access or transmit randomly. This question is intimately related to the issues of power and transmission rate control as well as to the issue of what the performance measure is.

We formulate the access problem in a layerless fashion and chart a methodical way of solving it. Ultimately, the resulting trade-offs are difficult to resolve, but in certain cases useful insights emerge that shed light into the resource allocation problem at its fundamental level.

NANONETWORKS: A New Frontier in Communications

Nanotechnology is enabling the development of devices in a scale ranging from one to a few one hundred nanometers. Nanonetworks, i.e., the interconnection of nano-scale devices, are expected to expand the capabilities of single nano-machines by allowing them to cooperate and share information. Traditional communication technologies are not directly suitable for nanonetworks mainly due to the size and power consumption of existing transmitters, receivers and additional processing components. All these define a new communication paradigm that demands novel solutions such as nano-transceivers, channel models for the nano-scale, and protocols and architectures for nanonetworks. In this talk, first the state-of-the-art in nano-machines, including architectural aspects, expected features of future nano-machines, and current developments are presented for a better understanding of the nanonetwork scenarios. Moreover, nanonetworks features and components are explained and compared with traditional communication networks. Novel nano-antennas based on nano-materials as well as the terahertz band are investigated for electromagnetic communication in nanonetworks. Furthermore, molecular communication mechanisms are presented for short-range networking based on ion signaling and molecular motors, for medium-range networking based on flagellated bacteria and nanorods, as well as for long-range networking based on pheromones and capillaries. Finally, open research challenges such as the development of network components, molecular communication theory, and new architectures and protocols, which need to be solved in order to pave the way for the development and deployment of nanonetworks within the next couple of decades are presented.

Ian F. Akylidiz received his BS, MS, and PhD degrees in Computer Engineering from the University of Erlangen-Nuremberg, Germany, in 1978, 1981 and 1984, respectively.

Title:ن Let There Be Light and Sustainable Energy-Efficient Wireless Applications

As we step further into the 21st century, the demand for sustainable energy-efficient technology grows higher. The important area of electric lighting, currently dominated by decades-old incandescent and fluorescent sources, is being taken over by White Light Emitting Diodes (WLED), which are solid state devices with greater energy-saving. Replacement of current inefficient lighting by these LEDs will result in reduction of global carbon dioxide emissions, a major cause of global warming, among other things. The LED holds the potential, in the field of photonics, to be as transformational as the transistor was in electronics.نن This core device has the potential to revolutionize how we use light, including not only for illumination, but communications, sensing, navigation, imaging and many more applications. In this presentation, we will highlight some of the potentials.

Multi-dimensional Convergence of Broadband Access Technologies in the 21st Century

With the rapid growth of bandwidth demand of emerging data and high definition digital video services, radio-over-fiber technology has gained tremendous momentum due to its ability to increase network capacity, bit rate, coverage, and mobility by seamlessly integrating optical fiber and wireless access systems. Owing to globally available multi-gigahertz bandwidth for wireless transmission, the millimeter-wave (mm-W) bands at 60-90 GHz with negligible interference with existing radio-frequency wireless services are playing a vital role for next generation very high throughput wireless local area networks (WLAN) and wireless personal area networks (WPANs). Several industrial and standardization efforts have been established, such as IEEE 802.15.3c (WPAN), ECMA-387, and IEEE 802.11ad (WLAN), to usher in global use of multi-gigabit MM-Wave wireless technology. In this talk, we will highlight recent progresses in system design and experimental demonstration of converged multi-band and multiple services wireless and wired access technologies based on optical millimeter wave signal generation, processing, and low-cost mm-W transceiver for multi-gigabit data transport in wireless over fiber access networks.

Physical Layer Security in Wireless Networks

Security in wireless networks has traditionally been considered to be an issue to be addressed at the higher layers of the network. However, with the emergence of ad hoc and other less centralized networking architectures, and networks (such as sensor networks) having low-complexity nodes, there has been an increase in interest in the potential of the wireless physical layer to provide communications security. The idea that the physical properties of a communications channel, rather than secret keys or trusted authorities, can provide security dates to Wyner’s 1975 study of the wire-tap channel. But, recent work has taken these early ideas and expanded on them considerably, by examiningهthis potential in a variety of basic wireless network architectures, and by considering the issues of fading, code design for secure transmission, feedback, authentication, secure network coding, among many others.ه This talk will review recent work and open issues in this field.


H. Vincent Poor is the Michael Henry Strater University Professor of Electrical Engineering at Princeton University, where he is also Dean of the School of Engineering and Applied Science.

Video Transmission: Recent Results, Challenges, and Opportunities

Supporting video communication over lossy channels such as wireless networks and the Internet is a challenging task due to the stringent quality of service (QoS) required by video applications and the many channel impairments. Two important QoS characteristics for video are the degree of signal distortion and the transmission delay. Another important consideration is the cost associated with transmission, for example, the energy consumption in the wireless channel case and the cost for differentiated services in the Internet (with DiffServ) case.

In this presentation we consider a cross-layer resource-utility allocation and scheduling framework for balancing the requirements of different applications. Our goal is to provide acceptable content-aware QoS while taking into account system constraints. We discuss a general framework that allows a number of "resource/distortion" optimal formulations for balancing the requirements of various applications.㺿 Examples include multi-user video streaming, robust streaming of scalable video and peer-to-peer multimedia streaming. We conclude the presentation with some of the grand opportunities and challenges in designing and developing video communication systems.

The Future of Human Communication

The invention of the telephone in 1876 was a major leap forward in making human-to-human communication more natural and immersive, leading to the quick decline of the telegraph.㺿 But the television, invented in 1926 as the visual counterpart to the telephone, did not have the expected impact.㺿 䄛Television䄥 quickly morphed into the broadcast medium it is today, while the visual counterpart to the telephone, now called video telephony, did not reach the market until the 1960s, when the AT&T Picture Phone proved to be a commercial failure.㺍 Eighty years after its invention, video telephony has changed little, except that we are now seeing little images on computer screens instead of dedicated devices.㺍 However, we are now at the threshold of rapid changes in visually immersive human-to-human communication.㺍 In this talk, I will show how recent telepresence systems are just a harbinger of the many changes to come.

Green Radio - The Case for More Efficient Cellular Base-stations

This presentation will discuss the power drain or efficiency of mobile terminals and base-stations to define the issues with current cellular systems operation, particularly in base-station or access point designs.㺿 Indications will be given for the total power consumption of (UK) cellular GSM and 3G networks.㺿 These issues are set to increase with the move from predominantly speech and text messaging to the increased roll out of smart-phones and mobile broadband, where the much higher data rate transmission requirements are not balanced by consequent increase in revenue. This is the primary driver for lower transmission energy per delivered bit.㺿
The second half of the presentation will review the approaches under investigation to improve the overall efficiency of base-stations and alleviate the high power drain to achieve 䄛green radio䄥 system design credentials with significantly reduced CO2㺍 emissions.㺍 The talk will address issues such as large versus small cell designs, definition of and highlight the benefits of employing femtocells, deploying relaying to delaying less urgent transmissions and save transmission power drain, employing sleep modes in the base-station when traffic volume is low, moving to use lower frequencies at modest load to exploit lower loss propagation conditions and finally how can we improve the overall efficiency of the base-station power amplifier.

This presentation is set in the context of industrial experiences in the Virtual Center of Excellence in Mobile Communications (Mobile VCE), an industry-UK government funded 䄛green radio䄥 research program conducted in 4 UK Universities in collaboration with 11 international industrial wireless sponsoring and program monitoring companies which includes the major service providers, equipment manufacturers etc.

Prof Peter Grant was on staff at Edinburgh from1971 until his retirement in 2009. He is now a Senior Honorary Professorial Fellow at the same University. Before joining Edinburgh, he worked at the UK for Plessey and Hughes for 5 years.㺍 He was appointed as the first head to form and integrate the School of Engineering at University of Edinburgh, leading it from 2002 - 2008.㺍㺍 Before that he served as Head of Electronics from 1999 - 2002.㺍

Peter Grant has three "doctorates", a PhD from the University of Edinburgh in 1975, an honorary DEng (Doctor of Engineering) from the Heriot-Watt University in Edinburgh in 2006 and another honorary DEng from Edinburgh Napier University, Edinburgh in 2007.

He holds five Fellowships from: IEEE, IEE/IET, Royal Academy of㺍 Engineering, Royal Society of Edinburgh and he was elected one of the㺍 first four fellows of the European Association for Speech, Signal and㺍 Image Processing (EURASIP), having previously served there as President 2000-2002.㺍 He was also awarded, in 2004, the 82nd IEE Faraday Medal.㺍 He served as a director of the Mobile VCE from 2007-2009.

Professor Grant was in 2007 appointed to be the 8th Regius Professor of Engineering at The University of Edinburgh. "Regius" i.e. regal chair appointments are conferred by the Queen of Great Britain.㺍 In 2009 he was made an officer of the order of the British Empire (OBE) in the Queen's birthday honours list.
