WSN electromagnetic wave propagation environments
Department of Electronic Engineering
University Federico Santa María
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.

: Post-IP Networks (knowledge, piloting, virtualization, security,
University Pierre et Marie Curie
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)

with Manycores and Heterogeneous Processors: The Productivity
The George Washington University
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.

: Maslow's Pyramid: Cloud Computing and the Ascent of
Bertrand du Castel
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.
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
