Routing protocols in Vehicular Ad hoc Network (VANET) have drawn lots of attention in recent years, most existing research efforts focus on designing IP-based protocols. In this paper, we present a new routing protocol for VANET based on Named Data Network (NDN). We optimize the routing path by using a new distance metric in the protocol, avoiding the shortcomings of hop-count based metric. Moreover, we use incremental broadcast and adaptive broadcast strategy according to vehicle density. In the experiment part, we construct a virtual urban scenario V-City to generate real world traffic and establish a coordinative test bed integrating SUMO with NS3. Simulation result shows that our protocol is more suitable for VANET environment than AODV.
