| Abstract(in English) | Recently, various technologies have been considered to increase the speed of wireless communications. On the other hand, as wireless communication technology improves, the number of wireless links on the communication path increases, and the impact on communication performance due to communication errors and propagationdelays has become a serious problem. Here, TCP communication, that is used in many applications, is an end-to-endcommunication method. Therefore, the sending node needs to wait for an acknowledgement from the destinationnode. If propagation delay is large, throughput degradation is significant. As a solution of this problem, Splitmechanism of TCP connection at a relay node has been proposed. This mechanism can improve the delay forretransmission. Therefore, splitting TCP connection immediately after a high-loss link is effective for improvingcommunication efficiency. However, in previous research, the splitting nodes of TCP connection is fixed, so thesenodes are not always placed immediately after the high-loss links. In this research, we propose an adaptive splittingmechanism of TCP connection in a network environment where heterogeneous communication links are mixed on aroute. The proposed method measures the packet loss rate on the link and dynamically changes the splitting nodesof TCP connection according to the packet loss rate. As a result of evaluating the proposed method in an emulationenvironment, it is confirmed that the proposed method can reduce the delay in the case of packet loss compared tothe previous method. |
