Analysis of Packet Scheduling in WiMAX Network

Interest in broadband wireless access (BWA) has been rising due to augmented user mobility and the requirement for data access at all times. The best available quality of experience is promised by IEEE 802.16 based WiMAX networks. For guaranteed services for voice, video and data, WiMAX networks include numerous quality of service (QoS) mechanisms at the Media Access Control (MAC) level. In order to provide different characteristics to Quality of Service (QoS) an effective scheduling is critical for the WiMAX system. Scheduling is an important part of WiMAX layers, which can be accomplished via downlink or via uplink scheduling. This paper gives a comparative analysis of two different schedulers Priority Queue (PQ) and Weighted Fair Queue (WFQ). The study has been carried out on a number of issues like: packet end to end delay and traffic received, and the simulation results shows that Weighted Fair Queue technique has a better quality than the other technique. OPNET Simulator has been used to create the Simulation scenario for WiMAX scheduling and result for different algorithm has been presented
