Performance Evaluation for UMTS and WiMAX in Handover

In this paper, we take voice as an application scenario to study the differences of Quality of service) QoS) between UMTS and WiMAX, We have designed and implemented WiMAX and UMTS simulation modules in OPNET and carried out extensive simulations to analyze the Mean Opinion Score (MOS), packet end-to end delay, jitter and packet delay variations for different type of voice traffic in these two networks.
