# The Concept regarding Vehicular Communications Based on Visible Light Communication and the IoT
## 4 Discussion  
Following the analysis of the proposal offered as a communication and security alternative, new directions were generated, especially concerning the use of VLC-RF and the two systems' integration in lighting systems, both in public and in vehicle lighting systems, to achieve communication of permanent data and in complete safety. These new approaches can address extremely pressing problems in today's society. It should not be overlooked that pollution and congestion are causes of traffic and mismanagement. The purpose of the proposal was to highlight the usefulness of VLC in systems other than the standard ones while, at the same time, indicating the high degree of security offered by the new standard compared to the existing ones. The communication through visible light employed in the proposed approach is performed in the PHY layers, resulting in unidirectional UDP connections in the first instance. The tests are in the early stages and have not passed the first stages where addresses are generated and packets with digital samples and minimal processing blocks are sent. Various parameters, sample rates, data rates, and modulation schemes have been studied, but no conclusions have yet been drawn, as these digital samples are routed internally without processing. An outline of a GNURadio-type processing block can be proposed that targets a future direction of being able to modulate the transmission bandwidth in both directions of the optical channel. When the intensity of the transmitted light is detected by a receiver and converted into an electrical current, unforeseen effects can occur. In this case, a file-type protection board on the transmitter-receiver path that can demodulate the received carrier signal is imperative. Thus, the data in Table 3 were extracted from the first stage of analysis of the presented proposal. The sources were retrieved and identified as the main data providers within the network, while the nodes represented the control units with destinations and sources. Figure 8 presents the degree of security of the data exposed in the information transmission process, showing that they do not deviate in the process they follow, nor do they present certain violations.

Visible light communication is considered extremely important because it is a new physical environment that promises to alleviate the pressure hovering over the use of the RF spectrum. This tool is becoming more and more common, highlighting the performance of VLC in the case of end-to-end network integrations. The purpose of this article was to highlight the diverse applications of VLC, its complementarity with RF, and, in particular, to process of emergence through which it can have an important role within the same system. The VLC model was validated by the tests and the measurements undertaken, but there is a need for the independence of VLC to be finalized, and questions arise as to how it can be used with Wi-Fi and RF, encouraging proposals for hybrid networks at scale. Instrumenting binaries with additional code sequences can be used to achieve a higher degree of routing by passing each instruction into the buffer dedicated to validation and generation of execution. Implementation at the architecture or prototype levels demonstrates leaps in tracking binary macs. Arguably, this implies the detection of unknown exploits from the previous parsing that trigger new routines in the buffer and create tags for system-wide validation. Therefore, any type of attack against the networks outlined on board vehicles can be successfully mitigated because such attacks cannot be backed by classic exploitation techniques, penetration tests, buffer overflows, packet injection, or fake routines. Through such an approach, it is possible to ensure that the information is and will remain private and the data are kept within the ECUs until the moment of validation by the issuer and confirmation that the data can travel the unidirectional route.
