A Study of LTE-V2X Mode 4 Performances in a Multiapplication Context

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 which vehicles allocate radio resources autonomously without cellular infrastructure support for direct vehicle-to-vehicle (V2V) communications. However, as is recent technology (compared WAVE and ITS-G5), it not sufficiently evaluated literature. In this work, we propose an evaluation performances considering impact sensing-based resource allocation mechanism parameters, traffic load Quality service (QoS) mechanism. addition, comparative study with ITS-G5. Based on several simulation scenarios from 3GPP, prove that Sensing-based SPS parameters significantly performance offered by LTE-V2X. show QoS outperforms ITS-G5 one realistic multi-application context.
