Secure Multi-Hop Relays And Cooperative Collision Avoidance For Autonomous Vehicles

Autonomous cars are receiving a great deal of attention, with many automotive companies expending time, money and resources to research and development in this area. However, there are still many challenges that need to be addressed before autonomous cars can be allowed on the public highway.

Collision avoidance is one of the main challenges and this requires accurate localisation information to be available to the vehicle at all time. Generally, this is obtained from GPS satellites, but there are many environments where the GPS signal is weak or lost and alternative sources of location information are needed.

Technologies such as Lidar, inertial navigation systems, 5G and Wi-Fi can all be utilised, as well as the internet of vehicles (IoV). It is therefore, important to design a protocol that can apply data fusion techniques to ensure the vehicle always knows its location under any conditions. However, in addition to precise positioning using data fusion methods, the sharing of location data between neighbouring vehicles is susceptible to security attacks, thus, the field of security in vehicle-to-vehicle (V2V) communication networks is receiving much attention and emerging standards such as IEEE802.11i, p and r allow data connectivity for fast moving devices. However, much of the data being carried across the vehicular network will be confidential only for a short time due to location information of the vehicle changing so rapidly.

This project will focus on obtaining precise positioning in real-time and providing solutions that minimize the security overhead.
