Performance Evaluation of WIMAX Network with WIMAX PHY using Different QoS?

The worldwide interoperability for microwave access (WiMAX) is one of the newest technologies developed for broadband wireless network which offers high data rates, long coverage area and several types of quality of services to the users. In this paper, a basic simulation and performance analysis of WiMAX network in three different scenarios, using different quality of services like WIMAX Physical Uplink and Downlink BLER, throughput, Network load, WIMAX Physical Pathloss and total Tx power is carried out using OPNET modeler which is a powerful tool used for simulation of wireless networks.
