Abstract: This paper investigates the scalable dissemination of databetween vehicles. The application context of this work is trafficinformation systems where cars are not only consumers but alsoproducers of information. The key challenge in those systems is toensure scalability in an environment where data is provided andrequested by all participating vehicles in a large area. We discusstwo fundamentally different approaches to this problem: usingdirect communication between cars and compressing the data viaaggregation versus relying on infrastructure. The latterapproach can further be divided into client-server and peer-to-peersystems. We outline all three approaches and highlight theiradvantages and disadvantages
