This study focuses on wireless communication for data transmission between vehicles. Wireless communication has become an essential part of modern life, playing a fundamental role in various applications. Different types of wireless communication networks are used in Vehicle-to-Vehicle (V2V) communication, including Radio Frequency (RF), Wi-Fi, and others. However, these technologies have certain limitations. For instance, RF-based communication has slower data transmission, which can delay vehicle responses and potentially lead to accidents. Wi-Fi offers faster transmission, but low signal strength can cause inaccurate data transfer, again posing safety risks. To address these challenges, Li-Fi technology is proposed. Li-Fi is an advanced wireless communication method that provides higher transmission speeds compared to Wi-Fi and RF. In this approach, Li-Fi is used for vehicle communication to help reduce road and fire accidents. The system includes sensors such as a gas sensor, fire sensor, alcohol sensor, and pressure sensor, along with an LCD display, Li-Fi transmitter, and an LDR as the receiver. Data is transmitted using LEDs. By integrating this technology into vehicles, safety can be significantly enhanced, reducing the likelihood of accidents. Beyond automotive applications, Li-Fi can also be utilized in smart homes, healthcare systems, industrial automation, and intelligent transport systems.
