Improving Traffic Information Retrieval in VANET with NDN

Traffic Information System (TIS) is a major application over vehicular networks. Decentralized TIS relies on vehicle-2-vehicle communications, and efficient traffic information dissemination is a major challenge. In this paper, we propose a preliminary design to support the traffic information retrieval in vehicular ad hoc networks (VANET). Our design adopts an information-centric communication model, and a probabilistic forwarding strategy based on names and geolocations. We implemented a prototype of our design and evaluated its performance in ndnSIM.
