Real-time services such as IPTV are becoming popular and are major revenue earners for network service providers. These services are no longer confined to the wired domain and are being extended over wireless networks. Although some of the existing wireless technologies can support some low-bandwidth applications, the bandwidth demands of many multimedia applications exceed the capacity of these technologies. The IEEE 802.16-based WiMAX promises to be one of the wireless access technologies capable of supporting very high bandwidth applications. In this paper, we explored and provide a good empirical values for system level WiMAX parameters by quantifying network performance using such video-rich services and get improved QoS for video transmission by measuring routing metrics parameters according to distance, modulation and power variation and discuss which system satisfy quality requirements along two transfer location modeled by network simulator, OPNET Modeler 14.5.
