Ensuring smooth communication by fixed‐cycle message beaconing in vehicular environments is necessary to address vehicles safety. However, fixed‐cycle beacon messages cannot accommodate the characteristics of fast vehicle speeds and variable network topologies and can cause problems such as channel congestion when traffic density is too high. Therefore, in order to realize safe and reliable information transmission between vehicles, this paper proposes a strategy for adaptive update of beacon message cycle based on vehicle driving stability. It is based on two rules: one is that the vehicle position prediction error is defined as an unstable vehicle, and the small error is defined as a stable vehicle; and the other is that the adaptive beacon message cycle is ranged, which is determined according to the channel load capacity. The experimental results show that the strategy can effectively avoid the channel congestion problem and improve the driving safety of the vehicle. Compared with the fixed‐cycle beacon message, the communication delay is reduced by about 10%, the packet loss is reduced by about 22%, and the energy consumption is reduced.

基于车辆行驶稳定性的自适应信标消息广播周期研究
为了解决车辆安全，必须在车辆环境中通过固定周期的信标信标确保顺畅的通信。但是，固定周期的信标消息无法适应快速的车速和可变的网络拓扑的特性，并且可能会在流量密度过高时引起诸如信道拥塞之类的问题。因此，为了实现车辆之间安全可靠的信息传输，本文提出了一种基于车辆行驶稳定性的信标消息周期自适应更新策略。它基于两个规则：一是将车辆位置预测误差定义为不稳定车辆，小误差定义为稳定车辆。另一个是自适应信标消息周期是有范围的，它是根据信道负载能力确定的。实验结果表明，该策略可以有效避免信道拥塞问题，提高车辆的行驶安全性。与固定周期信标消息相比，通信延迟减少了约10％，数据包丢失减少了约22％，能耗降低了。
