Abstract
V2X applications are based on heterogeneous networks that involve both a wired infrastructure (I) and a wireless network of vehicles (V). In this scenario, the transmission is characterized by broadcast messages (typical in vehicle to vehicle communications V2V) and unicast messages (typical in infrastructure to vehicle communications I2V or V2I).
According to the ETSI standard, vehicles are asked to periodically broadcast information like position, speed, and other specific metrics. The frequency of these messages is 10Hz, i.e. 10 messages per second. These broadcast messages are called Cooperative Awareness Message (CAM) and can be used by the infrastructure nodes, the Road-Side Unit (RSU), to collect the Received Signal Strength Indicator (RSSI) of each vehicle and map the link status between RSU and V.
The goal of the thesis is to create a centralized control system that takes advantages by the RSSI knowledge for solving the problem of routing packets in I2V applications. The novel solution is developed and compared with existing routing protocols. Results show that the new approach is able to maximize the number of correctly transmitted packets by minimizing the energy consumption of both RSU and V.
