针对超高速无线局域网的系统性能要求,提出了一种新的超高速无线局域网多用户多业务MUMS(Multi—us”andMulti—service)调度算法.基于对不同业务的服务质量QoS(Quality of Service)要求、用户信道状态信息CSI(Channel State Information)及服务队列信息的综合分析,此算法对业务和用户进行分层调度.仿真结果表明,在满足不同业务QoS需求且保证用户公平性的同时,提出的调度算法能有效地降低丢包率,提高系统吞吐量.
In this paper, a novel muhiuser and multi-service(MUMS) scheduling algorithm in the new ultra-high throughput (NUHT) wireless local area network (WLAN)system is proposed to meet the system performance requirements, which conducts a hierarchical scheduling of users and services based on a comprehensive analysis of quality of service(QoS) requirements, queue state information ( QSI ) and channel state information ( CSI ). The simulation results show that the proposed MUMS algorithm achieves a higher total throughput, a smaller packet loss rate as well as a good support of the QoS requirements and guarantees the fairness among users compared with the existing scheduling algorithms.
