The IEEE 802.16 Working Group on Broadband Wireless Access is developing the IEEE 802.16 standards for Wireless Metropolitan Area Networks. IEEE 802.16 standard aims at providing broadband wireless last-mile access in a Metropolitan Area Network, easy deployment, high speed data rate, large spanning area, and large frequency spectrum. WiMAX also provide an efficient quality of service architecture include priority scheduling and queuing for bandwidth allocation to support our network system more efficient. But we don’t know the performance in WiMAX system using different kinds of scheduling schemes for different sets of application flows.
Therefore, we have an idea to implement scheduling schemes on WiMAX system to compare with different scheduling algorithm in delay time, packet lose rate and throughput analysis in uplink and downlink direction to get better performance. By this way, those simulation results form our NS-2 WiMAX system can show which scheduling schemes is better clearly, then we can say which one is the best performance, which one suit for different specific environment and compare with other methods in simulation. Finally, we can support an efficient Queuing scheduling theory on dynamic bandwidth allocation to get better performance for the IEEE 802.16 system.
