Visible Light Communications - The Emerging Green Technology for Illumination and Data Communications

We are witnessing a growing research interest at a global level in visible light communications. Solid state light emitting diodes (LEDs) and organic LEDs (OLED) as well as organic photodiodes are seen as the next generation of general illumination sources, set to replace existing fluorescent and incandescent lamps offering much higher efficiency, longer life span and much lower power consumption.

Commercial companies are already offering the first generation LED replacement lamps with standard fixings available in high-street stores. In addition to lighting applications, the visible light spectrum can be used for indoor as well as outdoor wireless data communications, i.e. visible light communications. Visible light LEDs and OLEDs can be switched at sub-micro-seconds rate, which is too fast for the human eye to react but not for a special sensor on our portable digital devices. Thus, opening the way for dual use of visible light sources for illumination and data communications in homes, offices, cars, airplane, trains, etc.

This talk will give an overview of this emerging technology highlighting technical challenges and solutions for the LED and OLED lighting and data communications techniques.

Network-as-a-Service: Network Virtualization and Programability

Recently, we have witnessed dramatic changes in computing and communication demands with the introduction of mobile devices such as tablets and smartphones as well as the new paradigm of cloud computing. It is expected that by 2016 there will be three networked devices and 15 gigabytes data per capita in comparison to one networked device and 4 gigabyte data per capita in 2011. Networking and communications will become an even more critical service than it is already today . Moreover, networking is supposed to become a functional component of this new technological scenario and accessible to users as an added-value service rather than an infrastructure composed of bit pipes. In this talk, the state of the art in network virtualization and programmability will be overviewed to offer perspectives in the deployment of the so called Network-as-a-Service. 

Nelson Luis Saldanha da Fonseca received his Electrical Engineer (1984) and MSc in Computer Science (1987) degrees from The Pontificial Catholic University at Rio de Janeiro, Brazil, and the MSc (1993) and Ph.D (1994) degrees in Computer Engineering from The University of Southern California.

He is a Full Professor at Institute of Computing of The University of Campinas, Campinas, Brazil. He has published 300+ papers and supervised 50+ graduate students. As Visiting Professor, he lectured at the University of Trento, the University of Pisa and the University of Basque Country.

Nelson is an active IEEE ComSoc Volunteer. Currently, He is ComSoc Vice President Member Relations. He served as: Member-at-Large in ComSoc Board of Governors, Director of Latin America Region, Director of on-line Services. He is past EiC of the IEEE Communications Surveys and Tutorials, past EiC of ComSoc Electronic Newsletter and past Editor of the Global Communications Newsletter. He is Senior Editor for the IEEE Communications Surveys and Tutorials and Senior Editor for the IEEE Communications Magazine, a member of the editorial board of Computer Networks, Peer-to-Peer Networking and Applications, Journal of Internet Services and Applications and International Journal of Communication Systems.

He founded the IEEE Latin America Conference on Communications (LATINCOM) and the Latin America Conference on Cloud Computing and Communications (LATINCLOUD). He was technical chair of over 10 IEEE ComSoc conferences.

MANET formulation considered harmful and what is next?

Number of users/nodes in Internet has increased from 4 in 1969 to billions today. The number of cellular (2G, 3G and 4G) users also reached billions today, while only a 102 nodes of Mobile Ad Hoc Networks (MANET) was demonstrated after a few decades of extensive research with millions papers appeared in the literature. What went wrong with MANET? Are large scale Mobile Ad-hoc Networks possible? Is the MANET formulated correctly? There are several theories that have been forwarded as to why MANETs do not scale.

Our view is that MANETs formulated the problem too narrowly. In this talk, we will review some of the fundamental limitations of MANET both from theory and practice, and discuss some of the reasons why the current MANET do not scale. We recommend orienting the tactical networks research agenda toward self-* heterogeneous information networks with globally large extent. Here the self-* includes self-configuration, self-healing, self-optimization, self-protection, among others. Some of the key enablers or future research topics to achieve the true self-* heterogeneous network s will be discussed.

His research interests include wireless ad hoc networks, wireless sensor networks. He has published over 100 technical papers in IEEE Journals and key IEEE conferences (one of papers was listed as the top 10 most reading articles from  IEEE Communications Society website).  He has given many invited talks and tutorials on wireless ad hoc networks at various conferences and universities. He received the IEEE Regional/Area Outstanding Engineer award in 2011.

Twin Photons: Applications to Satellite Laser Ranging, and to Classical and Quantum Optical Communications

Twin photons, generated by spontaneous parametric downconversion, is a source of non-classical light with optical properties to transmit information in a classical and quantum form. The property that the twin photons travel with two difference optical frequencies has been proposed to quantify atmospheric refraction in Satellite Laser Ranging (SLR) measurements. The Universidad de Concepcion is running one of the two SLR systems with Twin photons transmitter operating in the world. A quantitative analysis of measurement precision, range accuracy, and data production will be presented. The analysis presented provides valuable input for the design of future SLR systems as well as related topics as optical communication to satellites. The property that this Twin photons are perfectly synchronized in time and space has been used to propose a classical optical communication channel based in coincident photon pairs. An exact expression for the mean rate of coincidence registration, developed using techniques from renewal theory, will be presented. The theory is apply to an on-off keying communication system proposed by Mandel. It will be shown that the bit error rate (BER) predicted by the approximate coincidence-rate theory can be significantly lower than the actual BER obtained using the exact theory. The important property of twin photons for quantum communications is that they are correlated in time and energy, allowing the creation of entangled states with these photon pairs. Entanglement is a fundamental resource for quantum information. In the Universidad de Concepcion there is active experimental research into the long-distance distribution of entanglement over installed telecom optical fibers. Results will be shown of the successful transmission of genuine energy-time entanglement over 1 km optical fibers, and initial results of two-photon coincident measurements across 4 km installed fibers in the Universidad de Concepcion campus.
