Susana Sargento from the University of Aveiro presented on a vehicular network platform developed by her team. Over the past 5 years, they have built the largest real-world vehicular mesh network testbed in Porto, Portugal. They have deployed prototype networking devices in over 500 public buses, trucks, and roadside units. This network provides continuous connectivity between vehicles as they move throughout the city. The presentation outlined the benefits of vehicular networks, how they work using WAVE and IEEE 802.11p standards, and the team's progress installing devices and visualizing the live network. Next steps include expanding the network to more vehicles and roadside units around the city to improve traffic efficiency and integrate sensor data.

2. Connecting Vehicles
Why communication in the
roads?
mobile data
(telcos are seeking WiFi
offloading solutions to
cope with 18x growth
in traffic until 2016)
continuous connectivity
(connectivity anywhere,
everytime)
connected cars
(all Internet-based
services in the cars)

10x range
100x faster

6. WIFI and WAVE
10x cheaper than cellular
(even 4G /LTE)
But, traditional WiFi is not prepared
for the vehicular dynamics: range
and association time
WAVE and IEEE 802.11p

7. Back 3 Years Ago
No WAVE/DSRC equipments available, or too expensive
We promise to connect 500 vehicles (by far the largest vehicular
testbed in the world)…
We developed our first prototype of WAVE /DSRC (drivers)

11. Pilot trials
After 5 years of R&D, we have built the largest
real-world test bed and collecting data in
Porto, Portugal.
We deployed new prototype vehicular mesh
networking devices with customers in more
than 500 vehicles (public buses, several
dozen trucks, road side units).
This is the most robust vehicular mesh network
in the world, delivering
The connectivity between the vehicles
The Quality of service and bandwidth while on
the move.

16. Next Steps
Expanding the Network
Other types of vehicles
Road side units around the city (expand in the central Porto)
Improve Network Functionalities
Integrating Sensor Information
Sensors in the buses
Sensors in the street
Cameras, environmental, polution
Driving and traffic efficiency
