Abstract

Multipath TCP (MPTCP) is an extraordinarily promising technology to guarantee service dependability in high-speed railway (HSR) networks. However, the phenomenon that wireless losses caused by frequent handoffs or other non-congestion losses in HSR networks has a detrimental influence on the performance of MPTCP. In order to improve performance of MPTCP when Long-Term Evolution for Railway (LTE-R) and WiFi communication routes are aggregated in HSR networks, we present a novel congestion control scheme, i.e., RVeno in this letter. Simulation results clearly reveal RVeno outperform the existing MPTCP congestion control algorithms in terms of throughput.
