Semi-TCP and ARQ combined end-to-end reliable transmission method

Abstract： In the wireless multi hop network environment, the data transmission is subject to more interference and the channel is unstable. Therefore, the traditional TCP protocol can not meet the communication requirements in this complex environment. The increase of ARQ retransmission between nodes will lead to a large cache occupancy rate and a low overall transmission performance. In order to solve this problem, Semi-TCP protocol and ARQ protocol are combined to lower congestion control to the link layer without changing the original TCP architecture, change the error correction capability of ARQ in the link layer, and improve the channel utilization. The simulation on Exata platform shows that this method can effectively improve the network transmission performance in wireless multi hop networks.
