EXPERIMENTAL ANALYSIS OF 802.11P BOARDS ON REAL VEHICLES

In this master's degree thesis, the tests are planned for real-world automotive scenarios using APU1D boards, built by PC Engines; a Swiss producer. On these boards an embedded Linux operating system (OpenWrt) is used, providing open-source development environment with a high degree of adaptability. IEEE 802.11p protocol was already implemented on these boards. These PC Engines boards are used as On-Board Units integrated with the electric vehicle that is used in this work. The main focus is to test the implementation of IEEE 802.11p and to investigate experimentally the data in real-world settings, with the main focus on Key Performance Indicators such as latency and throughput. The goal is to test our implementation and to analyze the performance of collected data, highlighting strengths and possible problems that could arise in real world implementation. The GPS device is also used in this work that is fixed inside the electric vehicle, and gives the speed and the distance covered by a car. The CAN network interface of the electric vehicle was also used to get the Engine RPM values. These RPM values are used to determine a real-time estimate of the vehicle speed by using a GPS and CAN data, by applying different speed filtering methods as it is not directly available through CAN.
