Spatio-Temporal Dynamics of Cellular V2X Communication in Dense Vehicular Networks

Abstract

Cellular Vehicle-to-everything (C-V2X) communication is a major V2X solution proposed and developed by the 3rd Generation Partnership Project (3GPP). Our previous work has studied scalability aspects of C-V2X and demonstrated its potential for accommodating large numbers of vehicles in dense vehicular scenarios. However, existing studies in the scientific literature mostly have a network-level approach to the problem and do not assess the temporal and spatial dynamics of C-V2X networks in heavy network load situations. In this work we shed light on the spatio-temporal characteristics of these networks and investigate the effectiveness of the congestion control algorithm in dense vehicular ad-hoc networks (VANETs) in terms of settling time, stability, and reliability to be employed for the purpose of safety-critical vehicular applications, where latency plays a major role.

On the Design of Sidelink for Cellular V2X: A Literature Review and Outlook for Future

“…With such approach, a conflict is observed between DCC and the sensing procedure, causing a degradation even worse than without any control (an issue also addressed in [100]). In [88], [89], congestion control mechanisms are, instead, considered following the American standards published by SAE and designed with DSRC in mind. The algorithms act on both packet generation and transmission power.…”

A Vehicle Message Scheduling Scheme For Vehicle Trust Management

“…Yang et al [4] proposed a decentralized trust management system that develops a blockchain based trustworthiness solution to address the consistent data issue. However, these existing solutions do not take into account the impact on quality of service (QoS), particularly in a dense traffic scenario [9], which may lead to a large transmission delay and a high report loss rate.…”

Stackelberg Game-Based Power Allocation for V2X Communications

“…Simulation results demonstrated the superiority of the proposed Stackelberg game-based power allocation scheme in comparison with the traditional power allocation strategy. Meanwhile, the proposed scheme achieved a better trade-off between economic profit and power consumption.Recently, there have been volumes of existing literature on V2X communications [5][6][7][8][9][10]. In [5], a cooperative automated driving (CAD) system based on collective perception and cooperative maneuver coordination was proposed, which could be applied to several use cases.…”

“…In [8,9], the performance comparison of IEEE 802.11p and C-V2X was presented. Moreover, the temporal and spatial dynamics of the V2X network were investigated in [10].In spite of the above attractive features and application scenarios, there are also a great number of problems in the coexistence of V2X communication and other networks, such as the resource allocation (RA), interference management on account of co-channel interference (CCI) caused by spectrum reuse. In order to solve these problems and achieve technical breakthroughs, several related works have been done in terms of RA, power control, congestion control, link scheduling, interference coordination, and so on [11][12][13][14][15][16][17][18][19][20][21][22][23].…”
