“…However, with simulations not shown here for brevity, it was noted that a too low R sel causes a slight increase in some cases. 3 With a smaller set of resources for the random selection of the BR, in fact, the risk of a collision increases if the choice is performed by two nodes at the same time from the same pool. And having the same pool is rather frequent for nodes that are located near to each other and thus sense similar interference.…”

“…In short-range C-V2X, two different approaches are defined for resource allocation, one under the control of the network, called Mode 3, and the other where decisions are VOLUME xxxx, 2018 1 arXiv:1807.10699v2 [cs.NI] 28 Nov 2018 fully distributed among nodes, denoted as Mode 4. Although Mode 3 is expected to outperform Mode 4 given the more information available at the scheduler [2], [3], still problems could arise at the cellular boundaries (especially with different operators) and the latter remains the only option when coverage is intermittent or not available.…”

In the latest years, 3GPP has added short-range cellular-vehicle-to-anything (C-V2X) to the features of LTE and 5G to allow vehicles, roadside devices, and vulnerable users to directly exchange information using the same chipset as for classical long-range connections. C-V2X is based on the use of advanced physical layer techniques and orthogonal resources, and one of the main aspects affecting its performance is the way resources are allocated. Allocations can be either managed by the network or in a distributed way, directly by the nodes. The latter case, called Mode 4, is required in those situations where the network cannot be involved in the scheduling process, for example due to a lack of coverage, but could also be adopted in order to reduce the processing burden of eNodeB. An algorithm, defined in the standards, makes nodes sense the medium and identify the best time-frequency combination to allocate their messages. Focusing on C-V2X Mode 4, in this work we analyse the parameters of the algorithm designed by 3GPP and their impact on the system performance. Through simulations in different large-scale scenarios, we show that modifying some parameters have negligible effect, that the proper choice of others can indeed improve the quality of service, and that a group of parameters allows to trade-off reliability with update delay. The provided results can also be exploited to guide future work. INDEX TERMS C-V2X, Intelligent vehicles, Vehicular and wireless technologies, Wireless networks

“…Several works have recently discussed the two technologies from various perspectives and a number of performance comparisons have been provided both in white [3][4][5][6] and peer-reviewed papers [7][8][9][10][11][12][13][14][15]. A common conclusion is normally that, given a target performance, the more advanced PHY layer of LTE-V2X allows for reaching a longer distance.…”

The revolution of cooperative connected and automated vehicles is about to begin and a key milestone is the introduction of short range wireless communications between cars. Given the tremendous expected market growth, two different technologies have been standardized by international companies and consortia, namely IEEE 802.11p, out for nearly a decade, and short range cellular-vehicle-to-anything (C-V2X), of recent definition. In both cases, evolutions are under discussion. The former is only decentralized and based on a sensing before transmitting access, while the latter is based on orthogonal resources that can be also managed by an infrastructure. Although studies have been conducted to highlight advantages and drawbacks of both, doubts still remain. In this work, with a reference to the literature and the aid of large scale simulations in realistic urban and highway scenarios, we provide an insight in such a comparison, also trying to isolate the contribution of the physical and medium access control layers.

“…Vehicular networks [1], aiming to provide wireless information exchange channels for vehicle to anything (V2X) communication, are currently attractive research areas. Compared with the traditional dedicated short range communications (DSRC) solutions, cellular-based V2X communication provides significant improvement in qualityof-service (QoS) guarantee [2] [3] and deployment cost reduction [4], and has recently been adopted as part of the 3rd Generation Partner Project (3GPP) Long-Term Evolution (LTE) Release 14 (R14) [5] (also known as LTE-V) and shown to be an important role in the future 5G networks [6] [7].…”

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.
