For effective packets scheduling in inter-vehicular communication, we design a hybrid priority-queuing model with a view to the difference of delay-sensitivity and packet length of services. By studying the transmission delay of 5 schemes, we prove that the non-preemptive short-packet-first scheme results in the minimal overall delay. In our scheduling model, the preemptive scheme is adopted for delay-sensitive services and the non-preemptive short-packet-first scheme is adopted for non-delay-sensitive services. The results from simulation experiments in NS-2 verified the superiority of our model by such performance indices as packet delivery ratio and throughput.
