Evaluación del desempeño de una HETNET de caravanas de vehículos en un sector del centro histórico de Quito.

Abstract

Mobility in the historical center of Quito has been impaired over the years, as a result of the increase in the city's vehicle fleet, and also due to the narrowness of the streets in the downtown area. To mitigate this effect, the management of intelligent cars can be considered, which have controlled and safe driving for pedestrians and drivers. In smart vehicles, there is a type of technology called vehicle caravans (Platooning), where a certain number of nearby vehicles meet and synchronize speed, braking and send other parameters about the road for better driving through vehicle networks. The standard that governs vehicle networks is IEEE 802.11p, however, this has a limited coverage range, so a type of infrastructure called RSU (Road-Side Unit) is deployed to communicate with distant vehicles. Another infrastructure already installed, such as the LTE network, is chosen to reduce costs, resulting in a HETNET. In this work, the performance of the HETNET of vehicle caravans in a sector of the historic center of Quito is evaluated by simulating two scenarios in which physical and/or technical parameters are changed in order to review the behavior of the network.
