  While the IEEE 802.11 protocol is being widely used, it is not specifically
designed to handle multimedia traffic, which covers an important portion of the
Internet traffic today. Voice and video multicast streaming is inefficient, as
there is lack of transmission reliability in such approaches where delay is not
guaranteed. In this work, we focus on the performance of Enhanced Distributed
Channel Access (EDCA) mechanism proposed by IEEE 802.11e which provides traffic
prioritization and since most of the previous works are done based on
simulation results, we test the performance of this protocol in a real platform
using sofware Defined Networks. We then validate the impact of different EDCA
parameters ( e.g., AIFS and TXOP) by tuning them to see their impact on the
delay of the network and eventually on network traffic.
