High speed train (HST) is becoming one of the preferred mid-range transportation and the on-board Internet service is a must for train operators. LTE networks paved the road toward high quality and cost effective on-board Internet in HSTs. However, frequent handovers (HO) for several onboard users overload sequentially cells along the train-track and increases the service interruptions, that in turn degrade untolerably the quality of service (QoS). HO service interruptions could be largely mitigated if HST could be virtually longer to access multiple cells from multiple devices coordinated in bundle. This is the paradigm of multi-cell access investigated here. More specifically, we propose a novel (and practically viable) onboard architecture for train-to-ground LTE backhauling. Multiple directional antennas with fixed-beams are deployed along the train to provide multi-cell access to distribute on-board traffics over at least three cells. Multiple antennas are paired with a load balancing mechanism for seamless on-board Internet. The combined use of multi-cell access and distributed load balancing mechanism provide a balanced QoS across all carriages that heavily mitigates the service discontinuities due to LTE HOs. The proposed architecture does not imply any change on network side. Conclusions are supported by numerical results for realistic LTE parameters in current HST settings. © 2014 IEEE

“…Our work resembles those concerned with designing stable schedulers for multi-queue multiservers systems [10]. An example system is IEEE 802.16e [12], where queues and servers correspond to mobile stations and sub-carriers respectively.…”

“…This means a scheduler may implement a policy whereby mobile stations are assigned servers/channels according to their queue length and channel condition. Halabian et al [10] proposed and proved the stability of a Any Server/Longest Connected Queue (AS/LCQ) policy. They preferentially assign servers to the most backlogged queue.…”

An Opportunistic Scheduler for Dense WLANs

The demand for bandwidth by multimedia applications remains unabated. This is particular critical given the growing number of devices with WiFi capability, and the ubiquity of Wireless Local Area Networks (WLANs). These trends have spurred researchers to develop low-cost and backward compatible solutions to increase the capacity of WLANs. One approach is to deploy additional Access Points (APs), and strategies to manage channel, user, and transmit power. As a result, stations are likely to be near one or more APs, and therefore are more likely to experience high data rates. In this paper, we take advantage of this fact to increase the capacity of a dense WLAN further by transmitting packets to a station via a neighboring AP if its associated AP is occupied by another station. Our approach is novel as prior works have not exploited the density and diversity of APs when scheduling downstream traffic. From extensive simulation studies, we show its viability in varying traffic scenarios, and in particular, WLANs with a high number of APs.s.
