In the wireless mesh network, an order error caused by non-congestion occurs, and TCP performs retransmission and congestion control at that time. In the case of the out-of-order caused by packet loss on wireless link, congestion control is not necessary because congestion does not occur. In the case of the out-of-order caused by route change, it is not necessary to perform retransmission and congestion control because congestion does not occur. We propose a method that judges caused by order errors and feedback the judgment result to the sending node so that the sender TCP control of retransmission and congestion control.
