Enhanced Frame Aggregation Scheduler (EFAS) for data Transmission over IEEE802.11ac

Wireless Local Area Networks (WLANs) based on the IEEE 802.11 standard are widely deployed in the home and enterprise segments across the globe. IEEE 802.11ac standard has brought several significant improvements compared to its predecessor IEEE 802.11n. It managed to break the Gigabits barrier with a combination of both refining older techniques and presenting new ones. The audio transmission over WLAN requires better Quality of Service (QoS). Over the time-varying characteristics of WLAN, better QoS requirement for the audio applications makes it a more challenging task. Presently IEEE802.11ac standard is in use for supporting WLAN with the main goal to provide higher throughput. This paper proposed an Enhanced Frame aggregation scheduler methodology in which proposed EFAS breaks the frames into smaller frames in the IEEE802.11ac standard and dynamically transmits the frame by analyzing the traffic. The evaluation of the proposed EFAS methodology is simulated in Network Simulator (NS2) by comparing it with the IEEE802.11ac standard method. The proposed methodology can be imposed at IEEE 802.11 MAC for achieving better audio quality.
