Abstract:

传统车联网通过蜂窝网进行信息传输,该传输方式延迟时间较长,难以应用于实时性高的报警信息的传输.然而,通过宽带无线网络的多跳广播方式,传输报警信息可以有效地减少延时.针对分布式车联网的特点,提出了基于地理位置、面向发送端的多跳交替广播协议AMBP(alternatingmultihopbroadcastprotocol).首先,根据邻居车辆信息表中记录的车辆节点信息,选择下一跳中继节点.然后,利用邻居车辆信息表中的信息,计算交替信息发送阈值.最后,根据报警信息数据帧长度与交替信息发送阈值的关系,采取不同的发送策略.实验结果表明,AMBP协议降低了丢包率,减小了多跳传输延迟和延迟抖动,适合应用在分布式车联网环境.
