Abstract

This paper reviews the fast deployment of Wireless Local Area Networks (WLANs) and the ability of WLAN to support real time services. Stringent quality of service (QoS) and high throughput requirements has come into force. We compare the QoS support in the IEEE 802.11e to 802.11n standard. The 802.11n frame aggregation mechanism provides a better video traffic transmission performance such as throughput, delay and packet lost. The 802.11e mechanism allows prioritized medium access for applications with high QoS requirements by assigning different priorities to its four access categories. The 802.11n implemented frame aggregation to get high throughput and low delay transmission. We evaluate the performance of both 802.11 standards by implementing real time audio and video traffic using Network Simulator-2 (NS 2) simulation. Parameters such as throughput mean delay and packet lost have been calculated and graphs have been plotted. Simulation results show that 802.11e mechanism provides satisfactory service differentiation among its four access categories. With frame aggregation mechanism in 802.11n, network delay has been effectively decreased to better support real-time audio and video transmissions.
