Resource allocation for Vehicle‐to‐Everything communications: A survey

Abstract

The Deployment of new techniques to accommodate high data throughput, significant reliability, and quality of service (QoS) delivery prompts the use of 4G and 5G networks in several applications. In these networks, Vehicle‐to‐Everything (V2X) communications authorised by device‐to‐device cellular links (D2D) have gained momentum because of their potential to improve road safety, efficiency, and convenience. This improvement is to be provided by different types of V2X communications, including Vehicle‐to‐Pedestrian (V2P), Vehicle‐to‐Vehicle (V2V), Vehicle‐to‐Infrastructure (V2I), and Vehicle‐to‐Network (V2N) communications. However, considering several limiting factors such as mobility and increasing number of vehicles, efficiency of using wireless resources is a challenging task. Indeed, different research works on V2X radio resource allocation have been studied and evaluated with respect to several criteria. In this study, a survey of recent works but in a different way synthesising radio resource allocation methods is presented. Resource allocation classification into different categories is proposed. This classification is related to three main factors. The first takes into account the selection mode factor. It highlights the use of different approaches in each of the centralised, distributed, and mixed modes. The second one takes into account the considered performance criteria, including capacity, priority, delay etc. The last one focuses on the methods and scenarios used to evaluate a resource allocation approach.

Towards 6G V2X Sidelink: Survey of Resource Allocation—Mathematical Formulations, Challenges, and Proposed Solutions

“…While the study [11] covers D2D resource allocation algorithms, our survey goes beyond LTE to focus on the evolving landscape of the 6G V2X Sidelink. The research [12] explores efficient resource allocation methods for V2X communications in 4G and 5G networks, whereas our survey investigates advancements and challenges leading to 6G V2X Sidelink. The study [13] presents a comprehensive survey on resource allocation for vehicular networks, including DSRC and cellular-based networks.…”

Optimizing V2X Communication: Spectrum Resource Allocation and Power Control Strategies for Next-Generation Wireless Technologies

“…However, the transition to 6G communications introduces a formidable challenge to the resource-allocation system, particularly when autonomous distributed vehicles are in operation, given the stringent requirements for extremely high throughput, low latency, and unwavering dependability [18,19]. This necessitates a comprehensive reassessment of the resource-management strategies to ensure the seamless integration of these cutting-edge technologies into the future landscape of connected and autonomous vehicles [20,21].…”
