Effect of Mobility Patterns on VoIP QoS in Mobile WiMAX
VoIP over Mobile WiMAX provides high data rate voice connectivity to high speed mobile as well as to fixed users. Voice over Internet Protocol (VoIP) enables the transport of voice data over internet protocol base networks. The WiMAX mobile network provides data services to both mobile as well as pedestrian users and the quality of voice is greatly affected with the mobility patterns of mobile users. The mobility behavior of the user plays an important role in determining the quality of Voice. For providing better quality of service to end user, the Mac layer of WiMAX defines various QoS classes for different types of applications.
