An efficient QoS scheduling strategy design for IEEE802.16 based on FPGA

A new two-layer scheduling algorithm is proposed in the paper, because the detail schedule algorithms guaranteeing Quality of Service (QoS) are not defined in IEEE 802.16. We design the IEEE802.16 architecture based on Embedded FPGA and study intensively on its QoS scheduling strategy. The new scheduling algorithm is developed from the classic 2-layer structure with new service flow priority, dynamically bandwidth allocation, admission control and compensation mechanism; which can meet the requirement of fairness and reliability on the service flow, also avoid the complex implementation of the algorithms to take into account the area and speed for FPGA design.
