一种超高速无线局域网多用户多业务调度算法

摘要

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.%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．
