Solve the problem of the quality of multimedia traffic in wireless networks is a very lively topic in the field of scientific research.
In this article, we present a solution to optimize the transmission of video in IEEE 802.11 wireless networks by changing the behavior of the MAC layer for video traffic; a breakdown of the latter on various types of access is proposed.
The platform operates using both improving the wireless standard IEEE802.11e and the inter-layer model proposed to improve the streaming media in wireless networks.
A test bench was performed to simulate this solution, using open source NS2 network simulator; the results obtained show that our solution improves visibly the most important indicators of multimedia transmission.

Abstract: (french)
Résoudre le problème de la qualité du trafic multimédia dans les réseaux sans fil est un sujet très vif dans le domaine de la recherche scientifique.
Dans cet article, nous présentons une solution pour optimiser la transmission de la vidéo dans les réseaux sans fil IEEE 802.11 en modifiant le comportement de la couche MAC pour le trafic vidéo; une ventilation de ce dernier sur les différents types d'accès est proposée.
La plate-forme fonctionne en utilisant à la fois l'amélioration de la norme sans fil IEEE802.11e et le modèle inter-couche proposé pour améliorer la diffusion multimédia dans les réseaux sans fil.
Un Banc de test a été réalisé pour simuler cette solution, en utilisant le simulateur de réseau open source NS2; les résultats obtenus montrent que notre solution améliore visiblement les indicateurs les plus importants de la transmission multimédia.
Author Keywords: réseau sans fil, 802, 11, EDCA, Evalvid, couche MAC.
