The priority assignment of messages effects on delay performance in VANET

Low delay performance between neighbor vehicles in VANT need to an indepth research. In this paper, we conceived a novel priority assignment plan to reduce transmission delay. A priority was assigned to each message based on static and dynamic factors and size of the message. Dynamic scheduling sequence was carried out based on the messages priority assigned. The performance of proposed method was analysed in highway scenario on the average delay and waiting delay in queue. Simulation results are consistent with theoretical deriving. Therefore, low latency environments can be provided in Vehicular Ad-hoc Network using the novel plan.
