One main characteristic of Vehicular Ad Hoc Networks (VANETs) is the intermittent connectivity, which leads to failures of end to end paths between end nodes. Named Data Networking (NDN) is a network paradigm that deals with such problems, since information is forwarded based on content and not on the location of the hosts. Hence, NDN has been proposed in VANET scenarios. In this paper, we propose a multihop and multipath VANET routing algorithm that exploits several paths to achieve faster content retrieval. We create a new routing approach for NDN in VANETs, by introducing new fields to messages and to data structures. Simulation results show that our approach does not only guarantee faster data delivery, but also saves network resources, due to the lack of message retransmissions.
