“…The influence of single-hop communication distance and road vehicle density on the delay of safety message broadcast is analyzed. In [8], the Poisson point process is used to model the position of vehicles on orthogonal roads, and the probability of successful transmission of typical general vehicles and vehicle messages at intersections are investigated. It is found that the interference signals are mainly from vehicles located on the same road.…”

With the emergence of autonomous driving and 5G mobile communication systems, how to design vehicular networks to meet the requirements of ultra-reliable low-latency communication (URLLC) between autonomous vehicles is widely concerned by the academia and industry. In this paper, message transmission delay and reliability between autonomous vehicles based on millimeter wave (mmwave) multi-hop V2V communications under urban road environment are investigated. Considering the fact that vehicles cannot come arbitrarily close to each other, shifted-exponential distribution is proposed to model the headway distance (the distance between the head of a vehicle and the head of its follower). Simulation results show that message transmission delay and reliability decrease with the increase of the path loss exponent and are also affected by the minimum safe distance between adjacent vehicles.Index Terms-Vehicle to vehicle communications, millimeter wave, shifted-exponential distribution headway, random relay selection

“…In vehicular networks, the locations of nodes are restricted to roadways and hence, these models do not capture the strong coupling between the locations of nodes and the layout of roads. While there have been a few works in which this coupling was considered, the analysis was usually limited to a single road or a set of roads modeled by a deterministic set of lines [4], [5]. Although these works offer useful preliminary insights into the behavior of the network, they do not account for the irregularity in the spatial layout of roads.…”

This paper analyzes the performance of a vehicular ad hoc network (VANET) modeled as a Cox process, where the spatial layout of the roads is modeled by a Poisson line process (PLP) and the locations of nodes on each line are modeled as a 1D Poisson point process (PPP). For this setup, we characterize the success probability of a typical link and the area spectral efficiency (ASE) of the network assuming slotted ALOHA as the channel access scheme. We then concretely establish that the success probability of a typical link in a VANET modeled using a Cox process converges to that of a 1D and 2D PPP for some extreme values of the line and node densities. We also study the trends in success probability as a function of the system parameters and show that the optimum transmission probability that maximizes the ASE for this Cox process model differs significantly from those of the relatively-simpler 1D and 2D PPP models used commonly in the literature to model vehicular networks.

“…For example, the wireless transmission resource allocation schemes have been proposed in [9]- [11], where the spectrum sharing, the wireless link assignment and the corresponding power adjustment are the key design factors to guarantee the transmission reliability and latency. In [12], the theoretical analysis on orthogonal street systems is reported. Although the above results provide a comprehensive study on the performance optimization in the physical and medium access layers, the following issues have not yet been investigated based on our present state of knowledge.…”

With the raising demand for autonomous driving, vehicle-to-vehicle communications becomes a key technology enabler for the future intelligent transportation system. Based on our current knowledge field, there is limited network simulator that can support end-to-end performance evaluation for LTE-V based vehicle-to-vehicle platooning systems. To address this problem, we start with an integrated platform that combines traffic generator and network simulator together, and build the V2V transmission capability according to LTE-V specification. On top of that, we simulate the end-to-end throughput and delay profiles in different layers to compare different configurations of platooning systems. Through numerical experiments, we show that the LTE-V system is unable to support the highest degree of automation under shadowing effects in the vehicle platooning scenarios, which requires ultra-reliable low-latency communication enhancement in 5G networks. Meanwhile, the throughput and delay performance for vehicle platooning changes dramatically in PDCP layers, where we believe further improvements are necessary.Index Terms-LTE-V, platooning, NS-3, SUMO A. Summary of Platooning and LTE-VVehicle platooning, by allowing vehicles to travel together, is shown to maximize highway throughput, reduce the traffic drug, and improve driving safety and comfort levels of automated driving simultaneously [16]. In order to support vehicle platooning capability, on board unit (OBU) with direct V2V communication ability to interchange important parameters in automated longitudinal control systems will be compulsory. In addition, as vehicle platooning systems often operate at a relatively high speed and the inter-vehicle distances need to keep small for traffic efficiency, a high reliable and low latency communication protocol is therefore required.Due to the similarity between device-to-device (D2D) and V2V communication, the sidelink mode 1 and mode 2, previously supporting D2D communication, have been upgraded to mode 3 and mode 4 for V2V communication in LTE R14, where mode 3 focuses on network supported vehicular communication and mode 4 targets to provide V2V direct transmission capability. With vehicle platooning scenario, we mainly consider the V2V communication in this paper and summarize the main features of the sidelink mode 4 in the following.
