一種考慮無線鏈路突發(fā)差錯(cuò)的TCP流量新解析模型

A new analytical model for the tcp throughput with bursty errors in wireless links

  • 摘要: 該文提出新的TCP流量理論分析模型,研究無線鏈路突發(fā)差錯(cuò)引起的分組丟失對(duì)TCP流量性能的影響。理論分析及數(shù)值仿真結(jié)果表明,該解析模型是合理的,既有較準(zhǔn)確的分析結(jié)果,又降低了復(fù)雜度。同時(shí),還表明在慢衰落信道中相關(guān)性越強(qiáng),TCP流量越大,獨(dú)立同分布信道的TCP流量是下界,即物理信道相關(guān)性對(duì)TCP流量是有利的。
    Abstract: A new analytical model for the TCP throughput, considering the packet losses caused by high and bursty errors in wireless links, is proposed. The analysis and numerical simulation prove that this model is exact and simple. And it is shown that channel correlations can result in better performance of TCP over slow fading channels, and the TCP throughput in i.i.d channel is the lower bound.
