Performance Analysis of a WiMAX/W-Fi System whilst streaming different Video conference applications with varying network loads

Abstract

WiMAX and Wi-Fi are considered as the promising broadband access solutions for wireless MAN’s and LANs, respectively. In the recent works WiMAX is considered suitable as a backhaul service to connect multiple dispersed Wi-Fi ‘hotspots’. Hence a new integrated WiMAX/Wi-Fi architecture has been proposed in literatures. In this paper the performance of an integrated WiMAX/Wi-Fi network has been investigated by streaming different video conference applications which vary the network load. The difference in performance between the two network connections WiMAX and Wi-Fi is compared with respect to video conferencing. The Heterogeneous network was simulated in the OPNET simulator. Results show that such a heterogeneous network can support a high resolution video conference application and a low resolution video conference application but not a VCR quality video conference application.
