摘要
无线传输中,拥塞控制算法Ntcp估计带宽波动性较大且估计值偏低。提出了Ntcp改进算法Ntcp’,它通过对发送端发送数据量更精确的计算,来消除带宽估计的波动性和纠正估计值偏低的问题。理论分析和仿真结果表明Ntcp’算法效果显著。
In the wireless environment,the method of bandwidth estimation for TCP based on channel noise model(Ntcp) has two disadvantages,one is the low estimated bandwidth and the other is the high fluctuation of the estimated bandwidth.With that,we proposed an improved algorithm(Ntcp')based on the amount of data sent by the sender.The analysis and simulated results show that Ntcp' works well.
