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 |
