AVAQ-EDCA: Additional Video Access Queue Based EDCA Technique for Dense IEEE 802.11 AX Networks

The main challenge of today's wireless network is the Quality of Service (QoS) of the medium. Now a days, many different types of Ultra High Definition (UHD) video types are introducing and online streaming of these videos are getting much popular to the users for the high quality viewing experience. But the conventional way treats all the video traffic in the same manner which may lead to the unusual delay of the real time streaming of UHD video traffic. Considering dense deployment scenario a new amendment is expecting to be announced called IEEE802.11ax on 2020 by making a big change in Physical layer features which will make faster data transmission in the network than ever. Moreover, in such huge contending situation there must need a suitable medium access control (MAC) protocol which can give priority access to UHD video traffic and can overcome the lagging experience of time critical video traffic. We have investigated this issue and proposed a novel technique to mitigate UHD video traffic scheduling problem.
