Abstract


The performance of reliability and efficiency are very important for message dissemination in vehicular networks. However, due to the high mobility of vehicles and the complexity of urban road environment, it is difficult to achieve good performance. In this paper, to solve these problems, we propose an effective message dissemination mechanism based on link lifetime and link utility. With full consideration of the characteristics of urban road, we present a new link lifetime prediction method in various scenarios. Furthermore, to evaluate the quality of the communication link between vehicles, a new link utility calculation method is proposed and the effects of different parameters involved on link utility are analyzed in details. Finally, simulation experiments are conducted to illustrate the performance of the proposed mechanism with the metrics of message coverage ratio, average delay and forwarding node ratio.
