Improving TCP Performance Over an On-Board Multi-Homed Network
Previously, a multi-homed NEMO architecture has been proposed to improve the reliability and aggregate the bandwidth of MR by simultaneously using multiple wireless links. In this paper, the authors propose a novel protocol called ETOM (Enhancements for TCP On a multi-homed mobile router) to improve the performance of sending a single TCP connection over multiple wireless links on a MR. ETOM consists of three components. First, they use a reordering buffer to eliminate unnecessary retransmission caused by out-of-order packets. Second, they develop a multi-homed split connection mechanism to enable the TCP connection to quickly adapt to the conditions of multiple links when packet loss occurs.
