Seminar presented by Professor Allen MacKenzie, E.T.S. Walton Visiting Professor

  • Location: CTVR Seminar Room
  • Date: 26 October 2012
  • Time: 13.00-14.00
The history of wireless communications can be told through the history of resource management. In this talk, Professor MacKenzie will describe the ongoing evolution from static to dynamic resource management and the concurrent evolution from homogeneous to heterogeneous networks. From this description, Professor MacKenzie will draw two themes for the future: (1) a need for a pragmatic, bootstrapped approach to dynamic resource assignment, and (2) a demand for robust approaches to automated negotiation between radio agents.
Along the first theme, Professor MacKenzie will show how unbounded dynamicism leads to failure; instead, we need pragmatically engineered systems that can bootstrap wireless communications from simple beginnings to complex sharing schemes. In particular, he will describe a proposed channel assignment scheme for cognitive radio networks that balances the need for topology adaptation to maximize flow rate and the need for a stable baseline topology to support network connectivity. Professor MacKenzie will focus on networks in which nodes are equipped with multiple radios or transceivers, each of which can be assigned to a channel. First, we assign channels independently of traffic, to achieve basic network connectivity and support light loads such as control traffic, and, second, we dynamically assign channels to the remaining transceivers in response to traffic demand. We formulate the problem as a two-stage mixed integer linear program (MILP) and show that with this two-stage approach we can achieve performance comparable to a fully dynamic channel assignment scheme while preserving a static, connected topology.
In the second theme, Professor MacKenzie will then describe the necessity of automated negotiation in future systems, including the relationship between these negotiated dynamics and the bootstrapped approach discussed in the first theme. In particular, he will explain some of the tentative steps that we have taken in this direction, including applications of auction theory and coalition game theory. Finally, he will introduce some potential tools and approaches for future research (and promote some future tutorial presentations on these topics).
Allen B. MacKenzie received his bachelor’s degree in Electrical Engineering and Mathematics from Vanderbilt University in 1999. In 2003 he earned his Ph.D. in electrical engineering at Cornell University and joined the faculty of the Bradley Department of Electrical and Computer Engineering at Virginia Tech, where he is now an associate professor. During the 2012-2013 academic year, he is an E.T.S. Walton Visiting Professor at CTVR: The Telecommunications Research Centre at Trinity College Dublin.
Prof. MacKenzie’s research focuses on wireless communications systems and networks. His research interests include cognitive radio and cognitive network algorithms, architectures, and protocols and the analysis of such systems and networks using game theory. His past and current research sponsors include the National Science Foundation, Science Foundation Ireland, the US Army, the Defense Advanced Research Projects Agency, and the National Institute of Justice.
Prof. MacKenzie is an associate editor of the IEEE Transactions on Communications and the IEEE Transactions on Mobile Computing. He also serves on the technical program committee of several international conferences in the areas of communications and networking, and is a regular reviewer for journals in these areas.Prof. MacKenzie is a senior member of the IEEE and a member of the ASEE and the ACM. He is the author of more than 50 refereed conference and journal papers and the co-author of the book Game Theory for Wireless Engineers.

CSET Thesis in 3

Thesis-in-3-2012-182Location: Smock Alley Theatre, Dublin 8
Date: 25 October 2012
Time: 6.30pm

The third CSET Thesis in 3 took place on 25th October in the Smock Alley Theatre. The event showcased the research of 18 students from 9 SFI funded CSETS (CLARITY, SBI, CNGL, CRANN, Lero, BDI, CTVR, APC and DERI). Both Séamus Hickey (UL) and Emanuele Di Pascale (TCD) represented CTVR at the event. Emanuele was awarded the audience prize for his presentation entitled ”Buy Local” Paradigm for Next Generation Networks”, which outlines how Fiber-to-the-Home will bring high speed connections to our neighbourhoods, but it will also reduce the capacity gap between these residential access segments and the main information highways in the center of the network; which can lead to congestion. Emanuele proposes the application of the ”buy local” paradigm to future networks, redistributing content in your local community through peer-to-peer, one can avoid costly data transfers through the center of the Internet. His research shows that this approach can improve user experience by speeding up communications, while at the same time reducing power consumption and operational costs for network operators.

We wish to congratulate both Séamus and Emanuele for their hard work and presentations.

The event was co-ordinated by Aoibheann Bird from CLARITY, Cara Greene from CNGL and Philip Smyth from Systems Biology Ireland.

Filling the White Spaces: Wednesday, 26th September 2012

TVWSLogoLocation: Science Gallery, Trinity College Dublin
Date: 26 September 2012
Time: 10am – 5pm

A spectrum opportunity awaits both consumers and the communications industry when the Irish analogue TV signals are switched off at the end of October 2012. The unused White Spaces that will surround the new digital signals of the Saorview system will be up for grabs.

But, who will use this spectrum? What will they use this new spectrum for? How will they access it?
Some of these questions have already been addressed by both industry and regulators in the USA and the UK where the digital TV switchover has already advanced. Suggested uses of this spectrum range from new WiFi-like devices for increased broadband connectivity, to machine-to-machine (M2M) applications, to new mobile network operator deployments.

The Filling the White Spaces workshop aims to inform an Irish audience as to these opportunities by sharing the experiences of companies that have already conducted trials in the UK and USA. We will also be looking to identify opportunities for Irish exploitation of this new spectrum resource in the context of on-going global developments.

Workshop Agenda:

10.00 Whitespaces introduction – Studios 1+2

This session is for those who feel they would like more background. They may want to know about the origins of the TV White Spaces or get a broad overview of what is happening around the world. There will also be a brief intro to some of the emerging ideas around spectrum sharing in general including Authorised Shared Access (ASA), the recommendations in the latest PCAST report in the USA on Realizing the Full Potential of Government Held Spectrum to Spur Economic Growth and the latest EU documents.

OFFICIAL START 11.15 TV White Space Networks in Action Abroad – Paccar theatre

This session marks the official start of the workshop and has a very practical focus. We will hear from those who have been involved in TV White Space Trials. There will be an opportunity to hear about the different target applications, the equipment used, the outcomes and the overall experience.

Microsoft – Jim Beveridge (UK) / Spectrum Bridge – Peter Stanforth (USA) /Adaptrum – Darrin Mylet (USA) / Neul – Paul Egan (UK) / FairSpectrum – Heikki Kokkinen (Finland) / BSKYB – Rafael Cepeda (UK)

13.30 Demonstrations in Studios 1+2 & Lunch

14.30 Ireland and White Space – where to next? – Paccar theatre

The purpose of this session is to determine what to do in Ireland. The first part of the session will take the form of a moderated panel. The questions which will frame the panel and subsequent audience discussion are –
1) What worth do ‘me-too’ trials have, i.e. replicating a trial that has been successful in another jurisdiction? Buy-in from local regulator, industry?
2) Are there new applications that can be trialled using the existing FCC/Ofcom rules?
3) What kind of TVWS applications could be trialled with new speculative rules that go beyond the
current FCC/Ofcom rules?

Discussion Topics – new applications for TV White Space bands, regulatory issues, economic challenges and opportunities, attitudes to sharing of spectrum in general, testing and trialling challenges, availability of equipment, opportunities for different players, the role of traditional media entities, the implications for mobile operators, the barriers to progress, the opportunities for intervention, funding etc. We are particularly interested in hearing from a wider range of voices outside of the purely technical and regulatory domain in discussing the opportunities for White Spaces.
16.30 Wrap-up

The final session will summarise the key conclusions of the day and identify a set of next steps.

17.00 Session closes in Paccar theatre + demonstrations continue in Studios 1+2


Registration has closed, thank you for your interest and for in attending.

Open Here Festival

Open-HereLocation: CTVR & TCD Science Gallery
Date: 28 June 2012
Time: 10am – 4pm

This four day festival that addresses social, technological and cultural issues surrounding the digital commons,will take the form of talks, presentations, workshops, discussions and screenings. It will be held in The Science Gallery and in CTVR headquarters in Trinity College.

What does it mean to be open today?

If we speak of ‘the commons’ today as a general phenomenon, this has a lot to do with the modes of production, consumption and distribution that have emerged over the last two decades around information and communication technologies. This period has seen a growing emphasis on the social and juridical implications of sharing in the online domain, where a range of nonmarket and non-proprietary activities such as open source software, remix culture and commons-based peer production have lead some to propose the advent of a ‘digital socialism’. However, as sharing and openness become the watchwords of the new corporation – as the commons is increasingly central to capitalism, such positions are no longer straightforward.


Open Here will bring together a transdisciplinary community of critical theorists, engineers, artists, designers and industry professionals to expand debates surrounding the digital commons.  Key points of discussion will include the conflictive spaces of the digital commons, tactical media, net-art, digital policy, disruptive wireless practices, alternative spectrum ownership models, next-generation networks and the political economy of infrastructure.


Participants include: Michel Bauwens (BE), Ralph Borland, (ZA) Sarah Browne (IE), CTVR (IE), Marika Dermineur (FR), Fairwaves (RU), Jessica Foley (IE), Tim Forde (IE) Benjamin Gaulon (FR/IE), Robert Horvitz (US), Dmytri Kleiner (UA/CA), Franco Lacomella (AR), Sascha Meinrath (US), Rachel O’Dwyer (IE), Julian Oliver (NZ), Nora O’Murchu (IE) Jussi Parikka (FI), Paul Sutton (IE), Tom Rondeau (US), Steve Song (ZA), Danja Vasiliev (RU), Martin Weiss (USA), Mick Wilson and Thomas Wilson (IE).


 This series of events is curated by Linda Doyle, Benjamin Gaulon and Rachel O’Dwyer and supported by ESOF2012, CTVR,  & Science Gallery, Trinity College Dublin.

Art, Activism and Economics

qr-webLocation: Studios 1 & 2, Science Gallery, Trinity College
Date: 16 February 2012
Time: 18:00 – 20:00


Data 51.0 brings together an international selection of media artists and theorists to explore the links between activism, art and business. Where open source, hactivism, and media art are still presented as ideologically opposed to the logics of information capitalism, the reality is that many hackerspaces receive corporate funding, open source platforms and user-generated content for the basis for many commercially oriented applications and much of the dominant media art of today is to varying degrees reliant on the financial trajectories of technological R&D.

Rather than denying this relationship or refusing to engage with the corporation, we want to ask how artists and activists might use their position in the market and their creative tools to critique, disrupt, or even potentially reshape commercial spaces from within.
