TR-13-04: A Store-and-Forward Dissemination Algorithm Using Locally Shared Vehicle Route Information

Abstract

Data dissemination within vehicle networks is an important research area as intelligent control algorithms can greatly benefit from accurate up-to-date information. This report proposes a dissemination algorithm that relies on the local exchange of vehicle routes to select appropriate data to broadcast, which can result in a more efficient use of limited bandwidth. The proposed algorithm is implemented within the Omnet++ communication simulator and experiments are performed to evaluate the algorithm’s behaviour using a bidirectional coupling with the SUMO traffic simulator. The results of the initial investigation of the algorithm’s performance show that it is capable of both selecting appropriate data to broadcast from a vehicle and limiting the amount of data broadcast to prevent flooding of the network. With these promising results, future improvements to the algorithm and intelligent traffic control research are discussed.
