【摘要】 本文提出了一种能够通过带宽估计来判断无线链路报文段丢失原因,并采取相应拥塞控制机制的无线TCP算法-TCP_LD(TCP Loss Detection)。文章采用Padhye模型的建模方法,推导了TCP_LD的稳态流量模型。理论分析和仿真结果说明,TCP_LD能够有效的区分出发生报文段丢失的原因,即拥塞丢失或者链路突发差错,从而提高系统的流量。更多还原

【Abstract】 In this paper,an improved wireless transport control protocol-TCP_LD(TCP Loss Detection) is proposed.Using bandwidth estimation,this scheme can distinguish the reason of packets error,hence adopt appropriate congestion control mechanism.Based on the TCP throughput model of Padhye,an analytical model of TCP_LD steady state throughput is deduced.The results show that TCP_LD is simple and effective for dealing with random packet loss,and can achieve significant throughput improvements.更多还原
