As part of its continued collaboration with Asia, INRIA is seeking to strengthen its relations with India, particularly with the Indian Institute of Science (IISc). This highly prestigious research organisation is based in Bangalore, a strategic town that is home to key industrial players from the ICST sector, including Microsoft, Philips, France Telecom and Google. An initial team associated with the IISc has recently been selected and INRIA is aiming, in time, to create a joint laboratory with this organisation.
How can mobile terminal
connections be managed on wireless networks to meet the increasing
demand for traffic? Should the choice of technology be left to the
mobile, the network, or a combination of both? Researchers from the MAESTRO project-team and Indian laboratories have been studying this question for several years as part of the Cefipra1 project and, today, this collaboration is continuing in the associate team Dawn.
Researchers in this team are studying and evaluating protocols that make it possible for mobiles to select the connection point as well as the technology used, whilst ensuring that the access point can refuse a new connection in the event of saturation. To this end, they are making good use of the combined skills in game theory and control theory found in the Maestro team and those in information and experimentation in the Anurag Kumar2 team from the IISc (Bangalore). Similarly, expertise in learning techniques and adaptive control from another member of the associate team, Vivek Borkar from the Tata institute of fundamental research (Mumbai), is invaluable when tackling the issue of multihop wireless networks. In this case, the terminals themselves are used as relays to send information to other mobiles. It is then a question of developing and testing a protocol that will make it possible for mobiles to self-configure and to adapt to the connection context. Finally the network security aspect is processed with the Saswati Sarkar team from the university of Pennyslvania, on the basis of work on zero-sum game theory.
"Collaboration with Indian teams puts us in contact with excellent students, some of whom are completing their thesis in our team”, highlights Eitan Altman, the French coordinator of Dawn. "Moreover, the industrial context in the Bangalore region is favourable to collaborations since numerous companies have set up their research laboratories and their development units in this area.”
