The Planète project-team, located both at INRIA Sophia Antipolis - Méditerranée and INRIA Grenoble - Rhône-Alpes research centers, conducts research in the domain of networking, with an emphasis on designing, implementing, and evaluating Internet protocols and applications. The main objective of the project-team is to propose and study new architectures, services and protocols that will enable efficient and secure communication through the Internet.
The Internet architecture is expected to evolve and the next-generation network must overcome the limitations of existing networks and add new capabilities and services. Future networks should be available anytime and anywhere, be accessible from any communication device, require little or no management overhead, be resilient to failures, malicious attacks and natural disasters, and be trustworthy for all types of communication traffic. It is therefore important to perform a balance of theoretical and experimental research that expand the understanding of large, complex, heterogeneous networks, design of access and core networks based on emerging wireless and optical technologies, and continue the evolution of Internet. In our project-team, we have chosen to address a small number of research directions focusing on the following domains which constitute essential building blocks for the future Internet architecture:
· Security in infrastructure-less and constrained networks;
· New modes of information dissemination;
· Seamless integration of wireless devices with the rest of network infrastructure;
· Understanding the Internet behavior;
· Experimental environments for future Internet architecture;
Based on a practical view, our approach to address the above research topics is to design new communication protocols or mechanisms, to implement and to evaluate them either by simulation or by experimentation on real network platforms (such as VTHD and PlanetLab). Our work includes a substantial technological component since we implement our mechanisms in pre-operational systems and we also develop applications that integrate the designed mechanisms as experimentation and demonstration tools. We work in close collaboration with research and development industrial teams.
In addition to our experimentation and deployment specificities, we closely work with researchers from various domains to broaden the range of techniques we can apply to networks. In particular, we apply techniques of the information and queuing theories to evaluate the performance of protocols and systems. The collaboration with physicists and mathematicians is, from our point of view, a promising approach to find solutions that will build the future of the Internet.
In order to carry out our approach as well as possible, it is important to attend and contribute the IETF (Internet Engineering Task Force) and other standardization bodies meetings on a regular basis, in order to propose and discuss our ideas in the working groups related to our topics of interests.
Our research activities are conducted in the context of national and European projects among them DIVINE (Video transmission over heterogeneous receivers and links), OSCAR (Overlay networks Security: Characterization, Analysis and Recovery), CAPRI-FEC (Design and analysis of Application Level FEC codes and application to mobile communications), ONELAB (An Open Networking Laboratory Supporting Communication Network based on PlanetLab), UBISec&Sens (Ubiquitous Sensing and Security in the European Homeland) and Expeshare (Enable Virtual Communities to Share Media Experiences).
To complete the golden chain, we collaborate with industrials such as Ericsson, Nokia, SUN, Docomo, Expway, UDcast, Hitachi, Alcatel, FT R&D, LGE, STM, Motorola, Intel, Netcelo, NEC, Boeing and others, to transfer the results of our research and/or to address together hard research problems.
