What is V2X Communication Standards?
V2X Communication Standards define the protocols for vehicle-to-everything communications, primarily comparing DSRC (IEEE 802.11p), C-V2X, and LTE-V2X standards in terms of latency, range, and interoperability within VANETs.
DSRC relies on IEEE 802.11p for short-range direct communications, while LTE-V2X uses 3GPP's PC5 sidelink for cellular-based V2X (Molina-Masegosa et al., 2017; 738 citations). C-V2X evolves to 5G NR V2X in 3GPP Release 16, adding advanced sidelink features (Castañeda García et al., 2021; 833 citations). Over 10 papers from the list analyze these standards' performance in vehicular simulations.
Why It Matters
Standardization of DSRC, C-V2X, and LTE-V2X enables deployment of cooperative intelligent transportation systems, reducing accidents through low-latency warnings (Naik et al., 2019; 544 citations). LTE-V2X supports short-range V2V via PC5 interface, improving traffic efficiency in urban scenarios (Molina-Masegosa et al., 2017). 5G NR V2X in Release 16 enhances reliability for autonomous driving applications (Castañeda García et al., 2021). These standards drive real-world pilots in Europe and field testing (Weiß, 2011; 152 citations).
Key Research Challenges
Interoperability Across Standards
DSRC and C-V2X lack seamless handover, causing communication gaps in mixed deployments (Naik et al., 2019). LTE-V2X faces compatibility issues with 5G NR evolution (Molina-Masegosa et al., 2017). Researchers simulate hybrid scenarios using SUMO to quantify impacts (Behrisch et al., 2011).
Low-Latency Performance Limits
DSRC struggles with high mobility-induced packet loss, while C-V2X improves via sidelink resource allocation (Ye et al., 2019; 791 citations). 5G NR V2X targets sub-1ms latency but requires spectrum optimization (Castañeda García et al., 2021). Evaluations use VSimRTI for runtime testing (Schünemann, 2011).
Spectrum Sharing Conflicts
V2V links reuse V2I spectrum, leading to interference in dense networks (Liang et al., 2019; 503 citations). Multi-agent reinforcement learning addresses dynamic allocation (Ye et al., 2019). LTE-V2X TD-LTE mode mitigates this but needs 6G extensions (Chen et al., 2016).
