摘　　要：为了提高有线/无线异构网络中TCP的传输性能,提出了一种新的接收方驱动的TCP拥塞控制机制TCP_LEB。该机制在接收方计算当前带宽和往返时间(RTT),并根据以往的带宽推导以后的可用带宽,然后反馈到发送方作为发送依据。同其他类似研究相比,该方法明显提高了无线网络中TCP的性能。仿真实验结果验证了算法的良好效果。To improve the performance of transmission through TCP in wired/wireless heterogeneous networks,Linearly Estimating Bandwidth(TCP_LEB),a newly receiver-driven wireless TCP congestion control mechanism,was put forward.In this mechanism,the current bandwidth and Round Trip Time(RTT) were computed in the receiver,the next available bandwidth was reckoned through the past bandwidth at the same time,and then the receiver sent the new bandwidth to the sender as a basis for sending.Compared with other similar researches,this method can obviously improve the performance of TCP in wireless network.The good performance of the algorithm was proved through the simulation results.
