ACROPOLIS 2nd Annual Workshop on “Advanced Coexistence Technologies for Radio Resource Usage Optimisation” and Industry Panel

The second ACROPOLIS annual workshop and industry panel will be organized in conjunction with the Wireless Innovation Forum European Conference 2012 (WInnComm-Europe 2012), and held on the 27-28 June 2012, in Brussels, Belgium.

The Industry Panel will take place on the afternoon of Wednesday the 27 June. It will include presentations from James 'Jody' Neel, Christophe Le Martlet, Maziar Nekovee, and T. Russell Hsing, as well as a panel discussion. The Industry Panel will be geared to inspire discussion on important developments and challenges in CR and other coexistence technologies, as well as discussion of innovative proposals in the area. Further detail on this event will be published in the industry section of the ACROPOLIS Website.

The Annual Workshop has been scheduled to take place on the following day, Thursday the 28 June. The topic of the workshop is the creation and use of coexistence technologies including cognitive radio and dynamic spectrum access to improve radio resource usage, such as to enhance achievable capacity and improve energy efficiency. The workshop will feature a set of technical sessions investigating various aspects of such coexistence technologies, as well as their benefits. The purpose of the workshop is to give all participants the opportunity to present their research results, and to facilitate the sharing of ideas.

ACROPOLIS Industry Panel—June 27

14:10 – 14:20 Opening of the Industry Panel

Quick summary of purpose of panel by Prof. Hanna Bogucka, Poznan University of Technology, including introduction of the panellists and their topics.

14:20 – 15:00 Industry Panellists’ presentations

• “One Question about Our Networked Life: Does the Internet Have an Achilles' Heel?” - T. Russell Hsing, Peking University and National Chiao Tung University

Most of us are experiencing on-line networked life every day (through Internet browsing, Google, You Tube, Face Book Twitter, Amazon, etc). It is reasonable to say that “i-Sanity” (e.g. iPhone, iPad, iTune, etc) is here now with most of our daily life. Using Game Theory, Optimization Theory, Feedback Control, Distributed Coordination and Strategic Equilibrium, the speaker will explain this key question and its implementation & applications in our daily life now those days. The speaker will share his thoughts, experiences and observations with the audience. It is hope that this talk could stimulate entrepreneur spirits for some of the researchers/engineers to pursue their dreams!

• “A Tragedy of White Space Commons?” - Maziar Nekovee, BT Research

Regulation of cognitive radio access to TV White Spaces (TVWS), using a geolocation database approach was very recently finalized in the United States and is at its final stage in the United Kingdom. The use of geolocation database offers a practical solution to the problem of primary systems protection and is of great interest to regulators and industry alike.
However, sharing of TVWS spectrum among white space devices is a major remaining challenge. The license-exempt access model may eventually result in a “ tragedy of white space commons”. Spectrum etiquettes (politeness protocols) used in the ISM bands were not designed for white space sharing where heterogeneous access technologies, high and low power, narrow-band and wide-band devices may have to live side by side.
Can a tragedy of white space commons be avoided? Can politeness protocols be adopted to for the new world of white spaces, or is there a need for complete overhaul? What role do geolocation databases have to play? During the panel I intend to share and highlight some of the above questions and explore potential answers.

• “Distributed frequency and power adaptation using learning algorithms for Cognitive Radio ad hoc networks” - Christophe Le Martret, Thales Communications

This presentation addresses the problem frequency and power allocation in the context of clustered ad hoc networks. The allocation is distributed at each cluster, which sets the transmit power level of the operation frequency without any signalling exchange between clusters. This algorithm is based upon a learning algorithm and exploits only one bit of feedback per receiver belonging to the cluster as sensing information. We study its theoretical performance by casting this algorithm into a game theoretical framework. We consider two different feedback solutions, one based on the SINR level estimation, and one based on the outcome of a CRC check. We analytically prove that this algorithm selects a suitable configuration for the network, and analyse its performance through numerical simulations under various scenarios.

• “Cognitive Radio Beyond DSA” - James 'Jody' Neel, Cognitive Radio Technologies

Much cognitive radio research has focused on enabling secondary access to underutilized spectrum, most notably the TV White Spaces. But the cognitive radio paradigm conceptually enables many more applications, such as reducing user burden on network management and setup, context-aware operation, automated interoperability, and more advanced radio resource management approaches. This talk will examine cognitive radio applications beyond DSA and identify research needed to realize these applications.

15:00 – 15:40 Panel Discussion

Moderated by Prof. Hanna Bogucka, Poznan University of Technology.

15:40 – 15:45 Conclusion and closure of the Industry Panel
