- Abstract
- Vehicle to everything (V2x) communication is one of the most researched topics today. The main goal behind this new emerging technology is road safety along with traffic and energy efficiency. Vehicular communications can further be sub-divided into certain types. One such type is vehicle to vehicle (V2V) communication, which is the focus of this thesis. V2V is either Wireless Local Area Network (WLAN) based or cellular based. In order to analyze and enhance this technology, real measurements need to be performed, which further require the use of different signal models.

For the thesis, the V2x WLAN based signal model has been used. This involved use of a V2x simulator for various stochastic channels and for a site-specific channel. The thesis is divided into three parts. The first part involves the building of a deterministic V2V channel model in the Unity 3D game engine. This deterministic channel is simulated by mimicking the 3D geographical properties of the Faculty of Engineering (LTH) premises of Lund University. The second part of the thesis is about understanding the V2x simulator. Further, the tasks involved analyzation of IEEE 802.11p and next generation 802.11bd protocols performance in stochastic channels. These stochastic channels were created using real-time measurements in ublox company. The final part of the project involves the use of the V2x simulator to assess the created V2V channel model. The proposed solution was to merge the deterministic channel to the simulator model. This was achieved by mixing the stochastic approach with our deterministic channel and then analyzing the performance. The results show that IEEE signal models in simulated line of sight (LOS) environment and in a stochastic LOS environment behave similarly. (Less) - Popular Abstract
- Since the development of vehicles, our life has become easier. But every positive value has its price in negative terms. With the increase in the car population, the accidents occurring from vehicles increased. Hence, there was a need to find a way to minimize accidents as much as possible, that is why the vehicular communication system was developed. A system is composed in a term called vehicular to everything (V2x), in which vehicles can communicate with each other or with other entities that may affect the vehicle. Therefore, by using V2x communication the number of accidents can be significantly reduced.
In the future, V2x communication will be implemented in a wide range of cars. Using V2x communications makes vehicles respond to...

With the increase in the car population, the accidents occurring from vehicles increased. Hence, there was a need to find a way to minimize accidents as much as possible, that is why the vehicular communication system was developed. A system is composed in a term called vehicular to everything (V2x), in which vehicles can communicate with each other or with other entities that may affect the vehicle. Therefore, by using V2x communication the number of accidents can be significantly reduced.
In the future, V2x communication will be implemented in a wide range of cars. Using V2x communications makes vehicles respond to any situation with a delay much lesser than of the average human’s time to respond to any situation while driving. For instance, if the driver of a car in front suddenly pushed the breaks in a high way, the vehicles behind with a V2x technology will respond immediately before the driver’s mind analyze the situation.
To measure and analyze the performance of the vehicle to vehicle communications (V2V), real-time measurements can be done using the various WLAN signal models (IEEE802.11p and IEEE802.11bd) of V2x. In this thesis project, analyzation of the performance of the WLAN signal models on different real-time stochastic channels is done by using the V2x simulator. A V2V channel model is simulated between two cars in a realistic 3D environment extracted from Google Earth. The latter is done to test the performance of the WLAN signal models on these types of deterministic channels. Hence, instead of doing real-time measurements, simulated channels can be used to measure and enhance the performance of V2x signal models. Lastly, a comparison between the performance of the WLAN signal model and the next-generation model was done on the simulated channel and on the stochastic channels. The performance of these signal models on the simulated 3D channel was noticed to behave similarly to the performance of the same IEEE signal models on one of the real-time stochastic channel scenarios.
