Message Forwarding between Vehicles in Dead Spots - English
MetadataShow full item record
The project for this master thesis aimed to study the concept of vehicle-to-vehicle communication in places with no or little Internet connection, so called dead spots. Collecting traffic information along the road is crucial to develop the future smart-car systems evolving. To distribute data to an external system, cellular network connectivity might be necessary. However, dead spots are challenging this approach. What I explore in this project is the idea of vehicles using each other as intermediary nodes when sending messages to infrastructure. Vehicle-to-vehicle communication using Radio Frequency (RF) technology might be the solution to the problem. If a vehicle within a dead spot is to send a message, it can forward this to another vehicle outside the dead spot for further forwarding. A communication application was developed to examine the reliability of vehicle-to-infrastructure communication in areas with intermittent network coverage. During modification, I determined the algorithm for the message forwarding when a vehicle enters a dead spot. Testing the application between different implementations made a basis for challenges to overcome in order to increase reliability. Both by studying related research and evaluating approaches used in the application, I give suggestions in order to achieve high reliability for vehicle-to-infrastructure communication.
