Proposed enhancement of IEEE802.11e wlan thruogh real time simulation study

Abstract EN

One of the most successful WLAN protocols is IEEE 802.11.

That is due to the simplicity and robustness against failures of its medium access control protocol.

In addition, IEEE introduces the standard 802.11e for quality of service support.

However this standard is not considered efficient when used for some applications that don't involve data and background in the transmission, but only voice and video.

Some of these applications are video conferencing and internal organizations voice over internet protocols calls.

For the purpose of enhancing voice over internet protocols and video streaming over IEEE802.11e WLAN, we have developed an ns-2 patch in C++ which suites our requirement in a simulation based performance enhancement.

In this paper, the performance of IEEE802.11e WLAN is evaluated and discussed based on simulation study using the network simulator (ns-2.29) under Linux operating systems fedora core 4.

Our simulation results showed enhanced performance for the voice and video traffics over the original IEEE802.11e standard.

This shows the video conferencing and voice over internet protocols.
