Susana Sargento discusses connecting 1 billion vehicles to the internet and each other through vehicular networks. She envisions a global network of connected vehicles that can expand wireless coverage, enable the internet of things, and improve urban life. Vehicles would act as WiFi hotspots using existing infrastructure and vehicle-to-vehicle communication to share real-time and non-time sensitive data. This could offer free WiFi on public transport to increase ridership while reducing emissions, and collect city-wide sensor data from vehicles to increase safety and efficiency of municipal services. The city of Porto has over 600 vehicles in its vehicular network pilot to transmit sensor information for applications like smart mobility, transportation, and urban planning.
