This letter investigates the problem associated with retransmission timeout (RTO) that is used in transport layer protocols. The current RTO algorithm is designed for wired networks, and is not properly prepared for IEEE 802.11-based wireless local area networks (WLANs). In this letter, a WLAN RTO (WRTO) algorithm, which can be applied to TCP and MPTCP is proposed. The experiments show that at poor channel conditions the proposed scheme results in a 18%, 29%, and 68% faster recovery time when compared to CMT-PF, cWPTCP, and CMT-QA, respectively, and also results in less spurious retransmission when compared to CMT-PF, which has the shortest recovery time among the existing schemes.
