Main achievements of the project
Significant work was done last year to complete
the deployment of and bring the European
platform, ANEMONE (Advanced NeXt gEneration
Mobile Open Network) to operational state.
ANEMONE is a large scale platform of wireless
technologies (WiFi, 3G, ...), grouping several
institutions throughout Europe. It will be the first
open without charge to third parties to test new
software or material solutions using protocols of
the future and offering innovative mobility
services (Mobile Ipv6, NEMO) for new generation
IPv6 networks. Based on the work carried out in
the framework of Labo4G (local authority
financed), the ANEMONE experimental network
and its associated services have been
implemented in the core network. A
communication effort (ANEMONE day in Rennes,
4G day, radio interviews) and several publications
and demonstrations have allowed to demonstrate
the interest of this tool and promote it.
The collaborative REMORA (ANR/RNRT) project
on mobile networks has been completed. It
designed a communications management
architecture for mobile networks allowing
embedded applications to interact with the
middleware managing communications interfaces
and resources. This middleware also takes into
account the operational constraints defined by the
operators and provides enough information to
applications for them to adapt their behaviour to
the network conditions.
The WiFi – WiMAX industrial project focusing on
the fast handover in secured heterogeneous
environment (CRE industrial contract with France
Telecom R&D Rennes) has been completed.
Within this framework, we have developed a
model taking up the network input protocol
exchanges for WiFi et WiMAX layers (including
signalling) in our SimulX homemade simulator.
Mohamed Kassab’s thesis [2] in particular,
contributed to these results, proposing methods
for the optimisation of the re-establishment of
contexts for different network architectures. The
WiNEM (ANR/RNRT) project with the PRATIC
project allows us to continue the development of
this simulation tool to make it available to the
community.
The LoCoSS project (PRIR 1
1) PRIR : Research project of regional interest
Région Bretagne), for
which we are responsible, has already triggered
several common publications dealing with the
transparent and opportunistic use of public
networks to offer advanced services (video, 3D
card,...) to the emergency services. It is entering
the integration phase for contributions from the
various partners (indoor localization, geolocalized
data bases, communications) and demonstrations
will be done next year.
We are involved in several other projects with the
following clusters : Mer (Sea) (IP Extrême) and
Images & Réseaux (Images and Networks)
(Locomotive, NextTV4All) as well as the
supervision of theses financed by the Region of
Brittany.
We have continued to develop our involvement in
intelligent transport, participating in several
programme committees and the scientific council
of GIS ITS Bretagne. We are also part of an
Embedded Systems commission with the
Automobile Haut de Gamme cluster.
We also maintain our high profile involvement in
standardisation bodies, we are part of work group
16 in the ISO 204 technical committee which is
developing a communication architecture for the
installation of Internet connectivity inside
vehicles. Although extremely time consuming this
involvement allows us to establish important
relations in the community of intelligent transport
and, more particularly, in the community of
intelligent vehicles. The latter currently has few
specialists in network and transport layers and
there is a high demand for expertise in this field
for European projects dealing with ITS.
Furthermore, we continue our active involvement
in IETF within groups working on mobility
management and multi-homing. Moreover, in this
context we offer header compression solutions
making it possible to limit protocol overload
relating to the use of IP on radio links.
Finally, we are developing research on networks
of sensors, focusing more particularly on routing
in interaction with channel access mechanisms.
Notably, this work was covered in Issam
Mabrouki’s thesis [3] within the framework of a
CIFRE contract with Mitsubishi Electric. The
thesis was defended in December 2008. The study
concerned totally random routing in data
