A Frame Aggregation Scheme with Two-level Buffer Mechanism and Service Differentiation

  • 摘要: 帧聚合是改善无线MAC(Media Access Control)协议信道利用率,提高频谱效率的有效手段之一。该文针对多业务场景,采用两级缓冲区调度策略,按照不同聚合权重因子对各队列轮询聚合。根据各个队列的包超时紧迫因子动态调整各队列的聚合权重,以满足各QoS等级业务的时延限制。该文还将排队论模型引入到帧聚合策略的性能分析中,建立了系统的数学分析模型,定量分析了主要性能参数与系统负载的关系。通过与IEEE 802.11n标准中定义的两层帧聚合策略比较表明,该文提出的帧聚合策略的性能优于IEEE 802.11n两层帧聚合策略。
