Abstract
In this paper, we evaluate the performance of different VoIP Codecs over WiMAX/Wi-Fi Integrated network. An integrated WiMAX/Wi-Fi network scenario is designed using QualNet 5. 0. 2 for VoIP application. This integrated network has a dual radio interface of WiMAX and Wi-Fi network. The network performance parameters such as Average one way Delay, Average Jitter, Average Mean Opinion Score (MOS), Packet loss have been used to evaluate the performance of VoIP Codecs. The simulation result is performed in QualNet 5. 0. 2 Simulator by varying the number of VoIP flows for different VoIP Codecs like G. 711, G. 726 and G. 729 in this WiMAX/Wi-Fi Integrated network. Simulation result shows that the codec G. 729 performs better than other two Codecs in terms of QoS performance parameters of VoIP.
