Abstract: The vehicle as a network nodes move faster, the network topology changes frequently, the link quality is unstable in the vehicle ad hoc network, which leads to the data can not be transmitted in a timely and reliable manner. Therefore, it is of great importance to enhance the robustness of the link. Considering these characteristics of the vehicle ad hoc network, a routing protocol based on link quality LQDF is proposed. Determine the size of the forwarding range according to the traffic density. In the forwarding range, the maintenance time of the link is calculated, including the position, speed and direction of the nodes. The longest link maintenance time is chosen as the relay node to transmit data. The simulation results show that the LQDF protocol improves packet delivery rate, and reduces end-to-end delay and network overhead to some extent.
