Amélioration des performances MAC dans les réseaux sans-fils
28 November 2008, by Mohammad NassiriDans cette thèse, nous étudions les principaux problèmes de performance qui surviennent au niveau MAC dans les réseaux sans-fil 802.11 lorsqu’ils sont utilisés dans un contexte ad-hoc ou multi-sauts. Nous proposons plusieurs mécanismes afin de résoudre ces problèmes de performance. Dans la première partie, nous améliorons la performance d’un réseau sans-fil en fournissant plusieurs classes de services. Notre mécanisme est une méthode d’accès qui permet d’allouer le débit de manière proportionnelle entre (...)

Mobility Management in Ambient Networks / Gestion de la mobilité dans les réseaux ambiants
22 November 2005, by Laurentiu-Sorin PaunAvailable online
This thesis was motivated by the new ubiquitous context of ambient wireless networks. The Internet protocols were designed 30 years ago without taking into consideration the nomadic use of networks and do not respond to the new constraints of mobility. We aimed to conceive mechanisms to make the mobility transparent to the applications and users. A part of our work was focused on the improvement of handoff delay of physical layer 802.11 to about 20 ms. Host mobility and (...) -
EU ICT CALIPSO 2011-2014
1 September 2011, by Franck RousseauCalipso website
CALIPSO builds Internet Protocol (IP) connected smart object networks, but with novel methods to attain very low power consumption, thereby providing both interoperability and long lifetimes. CALIPSO leans on the significant body of work on sensor networks to integrate radio duty cycling and data-centric mechanisms into the IPv6 stack, something that existing work has not previously done. CALIPSO works at three layers: the network, the routing, and the application layer. We (...) -
