Tutorial: WSN electromagnetic wave propagation environments
Presenter by :
Walter Grote
Department of Electronic Engineering

In Wireless Sensor Networks (WSN), data is collected from sensors to be transmitted using wireless technology. Important aspects for wireless communications are large and small scale propagation characterization, such as signal fading, channel coherence time and bandwidth, the Rician K factor and power delay profile. Many WSN applications are in open field environments, like in agriculture, on roads, on vehicles, etc. In these cases, propagation models for free space, line of sight, reflection, diffraction and scattering, shadowing and Doppler effects may apply. Home or office environments are also feasible, where the before mentioned effects are effective, but also propagation through wall or window panels may take place. Mining is another field of interest, either if it is underground or in open pits. Modern mining procedures aim to replace human resources directly involved in the mineral extraction process by automatic or remote control systems. Also, human health security issues in mines call for the use of wireless telecommunication systems. A new and exciting application field is the use of Underwater WSN (UWSN) where signal propagation becomes a major issue due to increased attenuations and delays.

WSN designers attending this tutorial will deepen their understanding of the design tradeoffs that will make it feasible to extend the networks lifetime. Since the propagation environment is also used by other technologies using wireless communications, people working in this area may also benefit from this tutorial. In this tutorial, emphasis will be on deriving boundary conditions for propagation conditions based on fundamentals, so that non-specialists in electromagnetic wave propagation issues may get a good grasp of the problems involved and their solutions.

Tutorial : Post-IP Networks (knowledge, piloting, virtualization, security, etc.)
Presented by:
Guy Pujolle
University Pierre et Marie Curie
Paris, France

Abstract: this presentation deals with important paradigms for the future post-IP generation: Knowledge and piloting planes, network virtualization and strong closed authentication. In this talk, we describe these four paradigms and finally we can deduce what could be the future post-IP generation.
So, first, we describe a complete environment based on Autonomic Networking, associated with a knowledge plane and a piloting plane, to control the Quality of Service (QoS) in IP networks and consequently responds to users’ requirements. Then we will describe network virtualization that can provide a powerful way to run multiple networks, each customized to a specific purpose, at the same time over a shared substrate. Finally, we introduce a high security scheme that can be deduced from a strong closed authentication where the customers can get a perfect privacy. We will compare the current TPM (Trusted Platform Module) solution with the future TEAPM (Trusted EAP Module) solution.

Computing with Manycores and Heterogeneous Processors: The Productivity Challenges
Presented by:
Tarek El-Ghazawi
The George Washington University
Abstract- As higher clocking speeds became infeasible, and the Moore’s law for clocking came to an end, the increase in integration levels continued giving rise to unprecedented chip architectural innovations and parallelism. These developments simply signaled the beginning of a new era, where manycore processors and heterogeneous processors including graphical processor units, cell processors and field programmable gate arrays, to give a few examples, are now delivering workstations with performance approaching the TeraFLOPS range. Current software programming solutions for those chips are quite fragmented and different from one another, posing serious problems in ease-of-use and portability. However, while manycores and heterogeneous processors have many differences, they also exhibit a great deal of similarities. While the differences require special attention, the similarities are sufficient to start addressing the potential for unifying and stable software solutions that cut across the overall software stack. Some of the solutions may also require support from the hardware. In this talk, I will to characterize the urgent challenges in computing with manycore and heterogeneous processors. I will also identify the new research directions in hardware and software that must be taken in order to enable effective and seamless use of these emerging architectures.

Keynote : Maslow's Pyramid: Cloud Computing and the Ascent of Computer Needs
Presented by:
Bertrand du Castel
Schlumberger Fellow

From its origin as on-demand exploitation of resources over the Web, Cloud Computing has been emerging as an encompassing model of interactions over a dynamic virtual network overlaid on the global communication architecture of the Internet. Colliding with the simultaneous development of the Semantic Web, a new organizational order is being established that disrupts the geography of mobility, urging a global model of trust governing new aspects of information exchange. From that trust derive policies mapping computer needs to human societies. This talk presents new cloud computing developments, their meshing with the semantic web, and novel definitions of trust that provide a formal model of evaluation.

Bertrand du Castel is Schlumberger Fellow. In the governing body of several computer organizations, Bertrand has published in artificial intelligence, linguistics, logic, and security. In 2005, he received the Card Technology Visionary Award for his work in pioneering the Java Card, the most sold computer in the world, past 5 billion units in 2007. Based in Austin, Texas, Bertrand is a graduate of Ecole Polytechnique and has a PhD in theoretical computer science for the University of Paris. In 2008, Bertrand du Castel and Timothy M. Jurgensen published Computer Theology: Intelligent Design of the Worldwide Web (Midori Press), a vast comparative description of religious developments in human and computer congregations.
