Prioritering av meddelanden för kommunicerande autonoma fordon (Swedish)
Abstract [en]

For autonomous vehicles to operate safely and efficiently they need to communicate messages with each other and the roadside infrastructure. Messages related to safety are more important than messages related to e.g. entertainment but the communication protocols of today do not allow for prioritization between these message types. In this report we analyze the possibility of such prioritization by extending simple medium access control protocols such as slotted-ALOHA and frequency division multiple access to allow for this. The performance of these extended protocols are then evaluated and compared using custom made simulations. We conclude that it is possible to prioritize between message types and that a combination of extended frequency division multiple access and slotted-ALOHA yields better performance results than one used separately.

Abstract [sv]

För att autonoma fordon ska fungera säkert och effektivt behöver dem kommunicera med varandra och infrastrukturmoduler. Meddelanden som är kopplade till säkerhet är viktigare än de som relaterar till t.ex. underhållning men dagens kommunikationsprotokoll kan inte prioritera mellan dessa meddelanden. I denna rapport undersöker vi möjligheterna för sådan prioritering genom att vidareutveckla enkla medium access control protokoll för att kunna hantera detta. Särskilt analyseras protokollen slotted-ALOHA och frequency division multiple access. Prestandan för dessa modifierade protokoll utvärderas sedan och jämförs mellan varandra med hjälp av egenbyggda simuleringar. Vi drar slutsatsen att det är möjligt att prioritera mellan meddelanden av olika typer och att en kombination av frequency division multiple access och slotted-ALOHA ger bättre prestanda än när man använder endast ena.
