In order to differentiate the small-scale propagation model and large-scale propagation model,this paper discusses the characteristics of the wireless channel and analysises the throughput of TCP(Transmission Control Protocol) under multipath fading channel.According to the current of estimation network bandwidth an updated TCP Congestion Control Mechanism protocol is explored.The different TCP versions of the protocol and the updated TCP protocol were simulated.The results show that the updated TCP protocol can take the congestion control mechanism more effectively.When there are network congestion and the multipath fading,17.8% throughput in the improved algorithm is improved than TCP-Sack.
