以车载环境下的无线接入（wireless access in vehicular environments，WAVE）网络中基于 DCF 的信道预约方案为基础，通过排队论的分析方法得出了采用该方案时系统中用户预约服务信道所需的平均时延，并研究了系统的主要参数对该平均时延的影响。研究结果表明，预约数据包生成的速率和最小竞争窗口对平均时延影响较大，最大退避阶数对平均时延影响较小。

We obtain the delay by queue analysis method based on the channel reservation scheme with DCF in WAVE (wireless access in vehicular environments),the delay is the duration from the arrival epoch at the head of the queue to transmission completion point.We research the influence of the main performance param-eters on the average delay.The result shows that the generation rate of reservation packet and the minimum contention window have a great influence on the delay,and the maximum backoff stage almost have no effect on the delay.
