A Safety Application of C-V2X Using Open-source MS_VAN3T Framework and IOT Protocol
The automotive industry is steadily progressing toward automation and making new technological revolutions. In the coming years, every vehicle will be connected through Vehicle-to-Everything (V2X) technologies. The important standardization bodies have done their part: IEEE, with the Wireless Access in Vehicular Environment (WAVE) stack, and ETSI, with the ITS-G5 stack, have contributed to defining the foundations of the Intelligent Transportation System (ITS) scenario for the United States and Europe. Additionally, IEEE proposed a protocol from the 802.11 wireless-LAN family, while 3GPP proposed a solution derived from the cellular networks (C-V2X).All these technologies will enable an incredible number of applications, which will overturn the mobility experience in all its forms. Simulation tools play a pivotal role in the automotive industry. Because of the complexity and the high deployment costs of vehicular applications, it is usually convenient to extensively test them through simulation. This thesis introduces an application of vehicular scenarios based on the open-source MS-VAN3T, an open source ETSI ITS-G5 model for the ns-3 simulator and that is coupled with SUMO (Simulation of Urban Mobility) which allows the reproduction of complex vehicular scenarios. Moreover, MS- VAN3T can be used to develop any kind of application and comes with the possibility of transparently changing the underlying access technology. These applications will leverage V2X technologies to improve road safety. For this reason, MS-VAN3T is used in this thesis to develop a Vehicle-to-Vehicle (V2V) system that, leveraging Cooperative Awareness Messages (CAMs) and Decentralized Environmental Notification Messages (DENMs), can warn vehicles and vulnerable users about possible collisions. V2X communication can be achieved through the internet of things (IOT) which can help stream information about all entities in the vehicular environment. The IOT technology has different protocols such as MQ Telemetry Transport (MQTT), Long Range Wide Area Network (LoRaWAN) and Narrow Band-IOT (NB-IOT), which is used to control the objects in the road infrastructure. For this reason, this thesis employs the MQTT protocol to develop a Vehicle-to-Pedestrian (V2P) system that leverages the pedestrians' time and safety.
