AB  - Presently, IEEE 802.11n is the latest WLAN standard that is deployed across the world. IEEE 802.11n
MAC layer is designed to achieve higher throughput up to 100 Mbps. The utility of video applications over
WLAN has increased greatly in today’s years. Real time video applications like video-conferencing are mainly
the time-bounded application. Whereas, A-MPDU frame aggregation process of IEEE802.11n focuses on
achieving higher throughput by aggregating the frames with reduced overhead. Aggregation process takes the
time to aggregate the frames which are not advisable for the critically time bound applications. Hence, a conflict
arises for transmitting the video application over the widely used WLAN standard. In this study, we propose
a time restraint tractable aggregation scheme for video transmission that aggregates the frames within the
desirable time interval. To do this, proposed methodology adds less number of frames based on the frame’s
delay threshold and traffic congestion. H.264/SVC video codec is used for the experimental evaluation. Our
experimental result shows that, the proposed methodology is providing better results in term of end-to-end
delay, jitter and PSNR. Thus for achieving better QoS, proposed time restraint tractable aggregation
methodology can be used for video transmission over WLAN.
