Abstract In recent years, with the great development in assisted driving, traffic monitoring and vehicle entertainment applications, vehicle networking (VANET) attracted a large number of academic research. Because of the vehicle mobility, wireless transmission ranges limit and the loss of wireless channel characteristics in VANET, providing a reliable multi-hop routing protocol in VANET is a significant challenge. This paper proposed a VANET routing protocol OPUVRE (Overall Performance for Urban Vehicular Routing Environments). OPUVRE is an overlay link state routing protocol .It uses traffic density, distribution uniformity and road length to calculate the score of each road, then uses the Dijkstra algorithm to select the best routing path. We evaluate OPUVRE against the traditional geographic routing protocols GSR and LOUVRE. The result shows that OPUVRE provides a higher performance in average packet delivery radio (PDR) and average latency.
