Geographic information-based data delivery in vehicular networks: A survey

With the convergence of IT and automobile technologies, one of the key challenges is to effectively deliver Internet-based data through the vehicular network. The conventional topology-based data routing mechanisms are not suitable in the highly dynamic environment of vehicular networks. The geographic location information acquired from the GPS can help in efficiently finding routes to the destination in the vehicular network. Therefore, in this paper, we provide the survey on geographic addressing and forwarding mechanisms for the vehicular network, especially focusing on the close relationship between addressing and forwarding.
