Abstract
The real-time service such as voice over internet protocol (VoIP) is considered the best type of conversational voice due to ability and the possibility of making a VoIP calls at any time and from anywhere with the lowest cost. In this paper, we explore the performance of UMTS and WiMAX networks for VoIP service. This work focuses on VoIP quality when sent under various network loads such as HTTP, Email, FTB and Video Conferencing. In UMTS network, the VoIP was congested with HTTP traffic, while in WiMAX network the VoIP was congested with many types of traffic such as HTTP, Email, FTP and Video Conferencing. These traffic flow effects on voice traffic are analyzed and evaluated in terms of end-to-end delay, jitter and packet loss with service quality (QoS). All simulation scenarios are performed with OPNET modeller 14.5.
