JDDR: A Joint Distance and Direction Routing Algorithm in Vehicular Ad Hoc Network

Abstract

Vehicular Ad Hoc Network (VANET) is nowadays an advanced and promising technology Vehicular routing often using Distance-Greedy (Always choose the vehicle which is the nearest to the destination geographically in the transmission range ) way to select next-hop However the main problem of this method is that the method just consider next hop not the overall situation; therefore perhaps the chosen next-hop’s future position is far away from the destination and even causes Local Maximum Accordingly the paper proposes the approach using GPS (Global Position System) navigation to obtain vehicles’ future moving direction to help us select an ideal relay to transmit the data in an effort to reduce the cost of VANET and to improve the transmission rate The main contribution of the work is proposing the method which considers vehicles’ position and future moving trajectory and to analyze proposed method in comparison with Distance-Greedy in terms of delay time cost and successful rate Finally the paper validates proposed method shows good performances on cost and successful rate
