The emerging adoption of wireless communications on surface transportation systems has generated extensive interest among researchers over the last several years. Innovative inter-vehicular communications and vehicle-to-infrastructure communications achieve road traffic safety, ecstatic driving and delightful travelling experiences. Multi-hop information dissemination in vehicular ad hoc networks is challenged by high mobility and frequent disconnections of wireless nodes. This paper presents a new routing scheme for Highway/Freeway VANETs, which consists of a unicast destination discovery process, a robust forward node selection mechanism and a positional hello mechanism. In this paper, no dedicated path is framed in order to prevent frequent path maintenance. In addition, the avoidance of flooding and location services substantially reduces the control overhead. Positional hello scheme ensures connectivity and diminishes control overhead concurrently. Simulation results signify the benefits of the proposed routing strategy (i.e. DDOR) has higher packet delivery ratio, reduced routing overhead and shorter delay compared with previous works.
