Normalized Uplink Bandwidth Scheduling Algorithm for WiMAX Networks
WiMAX networks can provide scalable cost-efficient universal broadband connectivity to end users. In WiMAX network, medium access control protocol schedules the bandwidth allocation to different traffic classes. To achieve quality of service requirements while scheduling the bandwidth, well-organized and reliablescheduling algorithms are needed. The existing algorithms are extracted from operating systems job scheduling algorithms, which are not suitable to fulfill the bandwidth requirements of WiMAX network. In this work, we have focused on uplink bandwidth scheduling algorithms. The proposed algorithms and existing algorithms are compared with respect to network throughput. Simulation results show that the proposed algorithms maximize network throughput.
