Abstract: Combining the repair link routing protocol and vehicular network, this paper proposes a new algorithm to predict the link break-time by turning time. It creates two accelerate model. One is accelerates velocity from current speed to the max speed, and the other is in the opposite. It discusses the movement of vehicle in 3 time zones to design the moving predict algorithm. It adds empirical prediction factor and enviroment prediction factor to improve the weighted prediction algorithm. Experimental results show that the algorithm can improve the predictive accuracy rate to 12.8%.

Key words: vehicular network, empirical prediction, environment prediction, link break-time
