Mobile Ad Hoc Networks in road transport applications exhibit special characteristics, mainly due to their dynamic chain behaviour. In this paper, we introduce a node decision algorithm in both the routing and packet priority mechanism, based on the node's driving direction with respect to the next hope towards packet destination. In the routing algorithm, a Router Direction Index (RDI) parameter is introduced to enhance the performance of AODV in updating its routing table, as well as to assist the destination nodes to choose route requests from different paths in inter-vehicular ad hoc network scenarios. A packet transmission priority is set according to the driving direction of both transmitter and receiver of the packet Simulation results of the proposed algorithm for 200 vehicles travelling at speeds between 60 - 120 km/h on a 2-directional highway demonstrate a performance increase in the packet delivery ratio, and decrease in the packet end to end delay and routing overhead for the proposed algorithm. © 2007 IEEE.
