# Supporting Immersive Video Streaming via V2X Communication
## 3 Simulation Results and Discussion
THz [54; 55] and mmWave [56] communications are employed to provide bandwidth for vehicle passengers' applications via V2I communication, while Li-Fi technology within the realm of optical wireless communication [57] is used to relay bandwidth for vehicle passengers' applications via V2V communication. Table 8 details the maximum achievable bandwidth and transmission distances for these wireless communication technologies. \begin{table}

Table 5: Minimum bandwidth requirements for PtCl live video. Figure 3 illustrates the variation in the number of vehicles throughout the day. The graph highlights significant peaks during the morning commute from 7 a.m. to 10 a.m. and the evening commute from 5 p.m. to 8 p.m., with peak values observed at 9 a.m. and 7 p.m., respectively. Vehicle flow increases notably during these peak periods. Between 11 AM and 4 PM, outside of the commute peaks, vehicle flow remains relatively stable, consistently above 3700 vehicles. As night approaches, vehicle flow gradually declines, with the lowest traffic occurring during the late night to early morning hours. Figure 4 illustrates the usage of video applications among vehicle passengers across various time periods, encompassing 2D video, 360-degree video, PtCl video, and MIV video, categorized into live and VoD formats. The graph demonstrates that VoD usage exceeds live usage across all video types, driven by the convenience of on-demand viewing. Furthermore, due to its widespread availability, 2D video shows the highest usage among all formats. Although the usage numbers for 360-degree video, PtCl video, and MIV video are significantly lower than for 2D video, the immersive video market is anticipated to grow significantly in the future, especially for 360-degree video, projected to rival or surpass the viewership of 2D video.
