摘要 IEEE 802.11e EDCA机制允许采用CFB(竞争空闲突发)模式,使站点在整个TXOP中都能对媒体进行控制,进而省去部分竞争信道的时间,提高服务质量,然而很少有文献考虑动态TXOP非饱和状态模型。提出了非饱和状态下TCP/UDP混合流的简单分析模型,该模型考虑了提高服务质量的竞争自由脉冲(CFB)模式。仿真结果表明,该模型能有效地预测混合流的EDCA机制性能,并反映出混合TCP/UDP流共用信道时会产生相互影响。 IEEE 802.11e EDCA mechanism permits using CFB（Contention Free Burst）,which will control the media in a whole TXOP.So it can save some time to occupy the channel and improve the QoS.But few papers think over TXOP in non-saturation.This paper proposed an easy analysis model of TCP/UDP heterogeneous flows appear in non-satura-ted condition based on IEEE 802.11e EDCA mechanism,the model thinks over CFB,the simulation results indicate that the model is valid on forecasting the EDCA mechanism of mixed flows,and the interaction of the mixed TCP/UDP flows appear when they share the same channel.
