Summary Due to unpredictable noise and ambient interference
along high-speed railways (HSRs), it is challenging to provide reliable
Internet services in severe HSR network environments. Most
existing research that requires expensive modifications for largescale
already in-used base stations cannot be immediately deployed
into the existing HSR systems. In this paper, we propose a quite
lightweight but effective solution to improve the Internet experience
forHSR passengers.Different fromother existing approaches,
we employ a data-driven link state prediction (LSP) mechanism
for HSR reliable transmission, called LSP4HSR, which directly
operates in HSR’s on-board routers. In particular, we conduct an
extensive measurement of network status on several realistic HSR
lines and collect a first-hand dataset in terms of round-trip time
and packet loss rate. By analyzing this real dataset, we find that
HSR link quality presents obvious two-time-scale variation characteristics.
We execute a lot of in-depth studies to explore potential
reasons for this interesting phenomenon. Furthermore, based on
the two-time-scale Markov chain, we establish an accurate HSR
link prediction approach, which brings an LSP-based transmission
enhancement mechanism to alleviate the impact from poor
link status along HSR lines. Extensive experiments verify that the
proposed solution can not only improve the packet transmission
reliability in HSR networks but can be also deployed in existing
HSR systems quite smoothly and easily.
