Abstract: The IEEE 802.16 provides QoS support, but it does not specify the details of how the QoS can be achieved for different types of applications. Since the gradual deployment of new multimedia applications generate traffic that is more sensitive to delay thus it required proper scheduling of packets. The objective of this paper is to analysis WiMAX network with and without scheduling methods by varying nodes density from 2 to 10 nodes. To recapitulate, WiMAX 802.16d gives better results with scheduling method (round robin) which is almost same with time and the performance parameters are throughput, packet delivery ratio and end-to-end delay.
