In this paper, we present an enhanced next forwarder selection scheme based on our previous work CODS-AD [4]. It enable vehicles to cooperatively assist source vehicle to discover the position of the destination without the help of location services and to adjust the forwarding strategy according to the road density. The proposed scheme overcomes the disadvantage of the greedy forwarding strategy used in CODS-AD where route stability is not considered and thus link-breakage probability is increased. In addition, proposed scheme make better decisions on how to select a more efficient and stable next forwarder by using location prediction and link duration estimation. The simulation result shows that the proposed scheme not only achieves a higher delivery ratio, but also significantly reduces control overhead and end-to-end delay.
