Title: Nanonetworks: A New Frontier in Communications

Abstract: 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.

Title: From Turing to the clouds:  What can be computed in a distributed system?

Abstract: One of the main issues addressed in A. Turing's work was about computability, namely, his Holy Grail Quest was to answser the question "What can be mechanically computed?". Since the definition of the Turing machine and the statement of the Turing-Church thesis, a lot of great technological advances have modified our view of what is a "computing device". Among them, distributed systems sometimes called "cloud computing"- are among the most pervasive, and force us to think again to the computability power of such systems.   The answer to this question depends  on the environment in which evolves the considered distributed  system, i.e., on the assumptions the system relies on.  This environment is very  often left implicit and  nearly always not formulated in terms of precise underlying  requirements. In the extreme case where the environment is such that there is no  synchrony assumption and the computing entities  may commit  failures,  many problems become impossible to solve (in these cases, a network of  Turing machines where some machines may  crash, is less powerful than a  single reliable Turing machine).  Given a  distributed computing problem, it is consequently important to know  the weakest assumptions (lower bounds) that give the limits  beyond which the considered distributed problem  cannot be solved. The talk will be  a short  introduction to this kind of  issues and  will focus mainly
on elements  related  to distributed  computability in distributed  fault-prone shared memory or message-passing systems. Its  style will  be  voluntarily informal.

Biography: Michel Raynal is a Professor of computing science at the University of Rennes, France. His main research interests are the basic principles of distributed computing systems. He is a world leading researcher in the domain of distributed computing. He is the author of numerous papers on distributed computing (more than 130 in int'l scientific journals, more than 290 papers in int'l conferences). He is also well-known for his eleven books on distributed computing. He has chaired the program committee of the major conferences on the topic (e.g., ICDCS, DISC, SIROCCO, OPODIS, ICDCN, etc.) and has served on the program committees of more than 160 int'l conferences including all the most prestigious ones. He is the recipient of several "Best Paper" awards (ICDCS 1999, 2000 and 2001, SSS 2009 and 2011, Europar 2010, DISC 2010) and has supervised more than 45 PhD students. He has been invited by many universities all over the world to give lectures on distributed computing. His h-index is greater than 50 (Harzing index).

In the recent past (2010-2013), Michel Raynal has written four books: "Communication and Agreement Abstractions for Fault-Tolerant  Asynchronous Distributed Systems", Morgan & Claypool  251 pages, 2010 (ISBN 978-1-60845-293-4); "Fault-Tolerant Agreement in Synchronous Distributed Systems", 165 pages, Morgan & Claypool,September 2010), (ISBN 978-1-60845-525-6); "Concurrent Programming: Algorithms, Principles and Foundations", Springer, 515 pages, 2012 (ISBN 978-3-642-32026-2), and  "Distributed Algorithms for Message-passing Systems",  Springer, 510 pages, 2013 (ISBN: 978-3-642-32026-2).
Since 2010, Michel Raynal is a senior member of the prestigious
"Institut Universitaire de France"
 

Title: Spectrum Sharing: Past, Present and Future

I will discuss the current regulatory issues and standardization/developments efforts  for cognitive radios in TV white spaces,  3550-3700 MHz, etc.

Although devices that are “sharing spectrum” are proliferating, they are not fully “cognitive”  in information theoretic sense.

Thus I overview information theoretic limits of cognitive transmission, and discuss that they may be hard to achieve in some scenarios given the current physical limitation.
