“…Moreover, some network architectures were proposed to establish communication links with reduced handover delays. The distributed antenna system (DAS) is commonly used in HSR communication scenarios, in conjunction with RoF, to overcome handover challenges and is considered to be among efficient approaches [132]- [134]. In this architecture, several RAUs are associated to the same control unit (CU), and are interconnected in a ring topology through optical fiber.…”

High-speed rail (HSR) communication has always been an attractive research topic with the continuous progress of transportation systems and communication technologies. Recently, Hyperloop has emerged as a candidate for very high-speed transportation systems. Because of its outstanding potential, Hyperloop can usher in a new transportation era with several attractive features. Developing suitable communication system solutions is crucial to bring this promising technology closer to reality. In addition, the Hyperloop communication system is essential to support monitoring-and-controlling services and deliver communication services inside its capsules/pods. Throughout this article, we overview Hyperloop technology and discuss its general characterization to recognize and estimate its relative position among the current HSR communication systems. Then, we investigate different attributes of the communication system, including network architecture, quality-of-service (QoS) requirements, and critical challenges to implement a reliable communication system. With the high speed of the capsule/pod and the system's unique structure, severe Doppler effect and frequent handover may considerably affect the operation of the communication system. Because Hyperloop is a recent development, it is necessary to study the existing HSR communication technologies to determine whether they can establish robust communication links for the Hyperloop system and deliver data with the required QoS. Furthermore, we provide technical details of the current HSR technologies and related research. Subsequently, we present the recent advances in the Hyperloop communication system with classification depending on whether it is a radio-, network-, antenna-, or software-based solution. Finally, we propose future research directions that can promote an improved communication performance.

The network planning is a key factor that directly affects the performance of the wireless networks. Distributed antenna system (DAS) is an effective strategy for the network planning. This paper investigates the antenna deployment in a DAS for the highspeed railway communication networks and formulates an optimization problem which is NP-hard for achieving the optimal deployment of the antennas in the DAS. To solve this problem, a scheme based on an improved cuckoo search based on dimension cells (ICSDC) algorithm is proposed. ICSDC introduces the dimension cell mechanism to avoid the internal dimension interferences in order to improve the performance of the algorithm. Simulation results show that the proposed ICSDC-based scheme obtains a lower network cost compared with the uniform network planning method. Moreover, ICSDC algorithm has better performance in terms of the convergence rate and accuracy compared with the conventional cuckoo search algorithm, the particle swarm optimization, and the firefly algorithm.

One of the prominent challenges for offering seamless communication system while performing vertical handover in heterogeneous network is to relay the communication without identifying the accurate demands of the resources as well as quality of services for the newly moved node. After reviewing the existing literatures, it was found that there is a potential research gap in addressing this problem of seamless vertical handover. Therefore, the proposed manuscript addresses this problem by introducing a novel analytical model which is capable of formulating a precise decision for controlling the selection /dropping of the data packets on the basis of dynamic state of the network condition. The proposed system contributes faster processing by arbitrarily selecting the packets to be forwarded with a very unique and simple resource management. The study outcome of proposed system highlights an increased throughput and reduced length of queue along with better fairness control to offer seamless vertical handover.
