在IEEE802.16e标准中,保证QoS的调度算法一直是人们研究的热点,它涉及到从单一业务到多级别业务的调度服务。对多级别业务调度的支持是保证系统性能的重要技术之一。本文针对多级别业务常用的分层调度和联合调度策略,从系统吞吐量、QoS性能和公平性等方面对之进行的仿真分析和性能比较。仿真结果表明联合调度策略综合性能较好。
In the IEEE802.16e standard, QoS scheduling algorithm has been a hot research topic, which involves scheduling service from single service to multi-level service. Support for multi-level business scheduling is one of the important technologies to ensure system performance. In this paper, the multi-level business commonly used hierarchical scheduling and joint scheduling strategy, from the system throughput, QoS performance and fairness aspects of the simulation analysis and performance comparison. Simulation results show that the joint scheduling strategy has better overall performance.
