It is defined as [n+T1, n+T2] where n is the instant at which the vehicle makes the decision for a new resource allocation, 1≤ T 1 ≥ 4 and 20 ≤ T 2 ≥ 100 (T1 and T2 are selected by the vehicle).…”

“…The papers [14], [15], [8], [16] present comparisons of the LTE-V2X performance with that of ITS-G5. Cecchini et al has shown in [14] that in a scenario characterized by a congested highway, the LTE-V2V mode 3 always outperforms ITS-G5 and LTE-V2V mode 4 regarding PRR, and that ITS-G5 provides better performance than LTE-V2V mode 4 for short communication distances.…”

“…These work are focused on the evaluation of the sensing-based SPS mechanism and the impact of its parameters on the performance offered by LTE-V2X ( [4] [5] [6] [7]). In addition, several work have been interested on the comparison of LTE-V2X and the IEEE802.11p type technologies (ITS-G5, WAVE) [8] [9]. Despite the number of works related to this issue, several shortcomings make that current knowledge of LTE-V2X performances remains partial.…”

With the growing importance of cooperative intelligent transport systems (C-ITS), 3GPP has standardized LTE-V2X (Long Term Evolution -Vehicle-to-everything) in Release 14 to address specifically vehicle-to-everything (V2X) connectivity. This standard introduces a mode 4 in which vehicles allocate radio resources autonomously without cellular infrastructure support for direct vehicle-to-vehicle (V2V) communications. However, as LTE-V2X is a recent technology (compared to WAVE and ITS-G5), it is not sufficiently evaluated in the literature. In this work, we propose an evaluation of LTE-V2X mode 4 performances considering the impact of the sensing-based resource allocation mechanism parameters, the traffic load and the Quality of service (QoS) mechanism. In addition, we propose a comparative study of LTE-V2X mode 4 with ITS-G5. Based on several simulation scenarios from 3GPP, we prove that the Sensing-based SPS mechanism parameters and the traffic load significantly impact on the performance offered by LTE-V2X. In addition, we show that the QoS mechanism of LTE-V2X outperforms the ITS-G5 one in realistic multi-application context.

“…OpenCV2X has been fully validated against [5] to ensure correctness of the model. Existing research published in [7], [8] use custom system level simulators but these are not available to the wider vehicular communications community limiting reproducibility. To the best of the authors knowledge, there exists only 2 system level simulators [9], [10], intended for contribution to the wider research community.…”

This paper presents OpenCV2X, the first publicly available, open-source simulation model of the Third Generation Partnership Project (3GPP) Release 14 Cellular Vehicle to Everything (C-V2X) sidelink, which forms the basis for 5G NR Mode 2 under later releases. This model is fully compliant with the existing vehicular service and application layers, including messaging sets as defined by the automotive and standards communities providing a fully standardised, cross-layer communication model. Using this model, we show how the current sidelink scheduling mechanism performs poorly when scheduling applications with highly aperiodic communication characteristics, such as ETSI Cooperative Awareness Messages (CAMs). We then provide the first indepth evaluation of dedicated per-packet aperiodic scheduling mechanisms, in contrast to schemes that parameterise the existing algorithm. This paper highlights that the level of aperiodicity exhibited by the application model greatly impacts scheduling performance. Finally, we analyse how such scheduling mechanisms might co-exist.

Two technologies are currently competing for providing Vehicle-to-Everything (V2X) communication services in Europe and in the 5.9 GHz ITS band. The oldest one is known as ITS-G5 and specified by ETSI, and the new comer is standardized in 3GPP and derived from LTE technology. It is now conjectured that both technologies will coexist in the deployment phase, at least during a transition period. Several coexistence scenarios are currently under study. Some of them are even considering the option to share a 10 MHz radio channel in the 5.9 GHz band among both technologies under the same geographical area. This approach is called co-channel coexistence. New mechanisms are currently explored and assume some modifications of the standards aimed at minimizing the performance losses. This co-channel coexistence scenario requires a careful assessment, and this article proposes the first performance evaluation in this particular context of coexistence between ITS-G5 and LTE-V2X standards. It presents a simulation work that has been carried out with the purpose of assessing performance of mixed deployments, and also assessing the efficiency of one possible coexistence mechanism. It is based on system level simulation which is itself relying on physical layer performance assessment pertaining to both technologies. The simulation methodology is presented and evaluation results are provided and commented.
