Awareness Information Dissemination using Aggregation into Collective Perception Messages for Connected Vehicles.

In the last few years, two critical situations have arisen in the ecosystem of Intelligent Transportation Systems (ITS) related to the Vehicle-to-Everything (V2X) radio technologies, that are delaying their commercial development. One is the unclear standard to use for this radio access layer, and the other is the limited coverage range of the used frequencies in the presence of obstacles, like buildings in an urban scenario. In this paper we present an infrastructure architecture, which utilizes edge computing that receives V2X messages in varying radio technologies and optimally forwards awareness information, using CPM messages, to all vehicles regardless of their radio technology, increasing at the same time the area where these messages are received.
