Providing Reliable Throughput with UPWARC as a Wireless Communications Architecture for High-Speed Trains

摘要

The study presented in this paper shows comprehensive simulation results of various in-train traffic loads generated by Wireless Digital Line (WiDTL)-related and passenger portable devices. It demonstrates the nature of these different traffic flows in different source, destination and aggregation points. Thus, by observing the various control- and user-application demands associated with High- Speed Train (HST) operations we can conclude that conventional networks fail to appropriately backhaul this data load. Keeping, this limitation in this mind we have proposed User Plane Wireless Adaptable Reliable Communication (UPWARC), which increases the network performance even in harsh time-variance. According to our study, it is possible for the envisioned UPWARC-based unified train communications architecture to provide high network performance and guarantee Quality of Service (QoS), in some aspects improving performance 15 fold, at the edges of cellular wayside base station coverage.
