QoS Multi-users Packet Scheduling Algorithm in IEEE 802.16e System

摘要：

IEEE 802.16e standard of wireless network defines the system structure of Quality of Service (QoS) and five service types, but it does not define fixed QoS scheduling algorithm. This paper ensures QoS features and improves the system throughput in OFOMA downlink system for the use of wireless packet scheduling algorithm. Combined with wireless communication features, Modified Deficit Round Robin algorithm(M-DRR) is proposed. The algorithm combines the channel conditions and application of hybrid automatic repeat request(HARQ) technology to Schedule wireless packet data. The simulation results show that M-DRR scheduling algorithm can improve the system throughput and provide some QoS guarantees.
