“…An optimal antenna assignment strategy [13] was proposed for employing maximum ratio combining. Along with the rise of Wireless Metropolitan Area Networks (WirelessMAN), the idea of information raining was extended in [14] to support network coding through IEEE 802.16j. However, it will produce a high deployment cost to provide seamless coverage by the information raining infostations along a track.…”

With the development of modern high-speed vehicles and mobile communication systems, there is a strong demand for operators to provide stable and high-quality onboard Internet services. However, the vehicle-to-ground links may suffer from several problems, such as insufficient bandwidth and long round-trip time. Although multiple wireless networks, such as WiFi, 3G and 4G, may be available along a track, onboard users hardly have good experiences if they can only visit the Internet via one wireless network, which may be subject to coverage gaps and signal attenuation. In this paper, the link qualities of multiple existing 3G and 4G technologies are first measured in a typical high-speed environment. These 3G/4G networks are candidates for vehicle-to-ground communication. Then, a concurrent multipath transmission scheme together with a network adaptive scheduling algorithm is proposed. The scheme is independent of the protocol stack so that it is easy to deploy. It also provides transparent Internet services for users without requiring the participation of the user devices in any multipath signaling. Meanwhile, the scheduling algorithm works at the network layer, instead of the transport layer, to meet the diverse transmission requirements of the connection-oriented and connectionless user applications. The algorithm can effectively aggregate the bandwidth of multiple available wireless links, as well as avoid the reordering of packets based on both the practical tracing databases and active path monitoring. Analysis and experiments show that the proposed algorithm can provide better onboard Internet services with lower cache requirements than the Earliest Delivery Path First (EDPF) and Weighted Round Robin scheduling algorithms, in terms of bandwidth improvement and packet disorder reduction.

“…Moreover, this algorithm can also be applied to the information raining system. Sue et al [22] proposed the network coding scheme for improving the performance of the high-speed train in IEEE 802.16 relay networks. Ho and Valaee [23] designed a novel system architecture that enables high-speed Internet access in railway systems.…”

“…In addition, they used packet fragment and repeater relay schemes to enhance the system throughput. The goals of these studies [21][22][23] focus on high throughput in a highspeed train environment without taking handover problem into account, while this paper focuses on the handover procedure to allow low handover latency, low packet loss and signaling overhead.…”

Abstract-High-speed rail systems are becoming increasingly popular among long-distance travelers. With the explosive growth in the number of mobile devices, the provision of high quality telecommunication and Internet access services on high-speed trains is now a pressing problem. Network mobility (NEMO) has been proposed to enable a large number of mobile devices on a vehicle to access the Internet; however, several issues must be solved before it can be put into practice, e.g., frequent handovers, long handover latency, and poor quality of service. To resolve the above problems, we propose an LTE femtocell-based network mobility scheme that uses Multiple Egress Network interfaces to support seamless handover for high-speed rail systems, called MEN-NEMO. The results of simulations show that the proposed MEN-NEMO scheme reduces the handover latency and transmission overhead of handover signaling substantially.

Provision of high data rate services on train has attracted a great attention recently. In this paper, the issues of time division duplex (TDD) DAS, including coverage of remote antenna units (RAUs), echo channel effect and system deployment cost were analyzed. The timing drift problem while solving echo channel effect with moving cell concept in DAS was also depicted in detail. Furthermore, the frequency response, propagation model, and time dispersion parameters of the RoF-DAS channel will be analyzed with simulation. This paper provided analyzed RoF-DAS channel profile over high-speed railway communication system for future researches.
