Abstract:

A number of traffic classification studies have been accepted out on wireless LANs, which indicate that the wireless settings pose major challenges, especially for high bandwidth and delay sensitive applications. This paper aims to estimate a number of Quality of Service (QoS) parameters correlated to video conferencing over three major WLAN Standards 802.11a, 802.11b and 802.11g. To study the traffic characterization conduct of these WLAN standards, we have simulated the environment for each of these standards and accomplished experiments. Outcomes are verified through the delivery of prosperousH.261 video traffic import in OPNET-14 Network simulator. We found that a trade-off exists among the selected data rate, physical appearances and the frequency spectrum (number of channels) for every standard. The traffic of video conferencing is characterized over each standard in terms of delay routine, traffic performance and load and throughput performance. The results show that quality of video traffic is a function of the frequency band, physical distinguishing, maximum data rate and buffer sizes of WLAN standards
