This letter proposes a transport protocol for millimeter-wave (mm-wave) communications to shorten the time to resume communication after a mm-wave link is reconnected. The proposed method distinguishes whether a retransmission timeout occurs due to a mm-wave disconnection or network congestion. If a TCP sender detects a mm-wave disconnection, the sender keeps its retransmission timer to prevent the retransmission timer from increasing exponentially. We confirm the effectiveness of the proposed method using computer simulations.
