Demo: OverDrive - an Overlay-based Geocast Service for Smart Traffic Applications

For smart traffic applications like dynamic route planning, communication between traffic participants is of high importance. Traditional approaches rely on centralized, serverbased communication architectures, which raises scalability and privacy concerns. To address these problems, we proposed OverDrive [5], an overlay-based geocast service that is applicable in smart traffic scenarios and not prone to the shortcomings of centralized designs. Here, we present an interactive demonstrator of the OverDrive protocol that visualizes OverDrive’s neighborhood structures and routing approach in a realistic and highly mobile traffic scenario. Our demonstrator is realized as an extension to the overlay simulation framework OverSim [2].
