摘要/Abstract

摘要： 为实现应急车辆与目的地之间的数据快速传输,提出一种面向应急车辆自组织网络的快速路由协议。该路由协议主要包括目的节点与通信车辆自适应选取、基础通信设施最优选择及应答消息快速回传4个步骤。依据传输距离、传输时间、车辆速度和中断链路数量计算相邻基础通信设施之间的类距离值,选择类距离值最小的基础通信设施作为数据传输的下一个基础通信设施,从而减少运行时间。仿真结果表明,与EM-AODV和EN-AODV路由协议相比,该路由协议可以明显降低端到端平均传输延时和应答消息平均响应延时,提高应急事件处理效率。

Abstract: A fast routing protocol for emergency Vehicular Ad Hoc Network(VANET) is proposed to achieve rapid transmission of data between the emergency vehicle and the destination.This routing protocol mainly includes four stages,i.e.,adaptive selection of destination node,adaptive selection of communication vehicles,optimist selection of infrastructures and quick return of reply messages.It calculates the similar-distance value between two adjacent infrastructures according to four factors,including transmission distance,transmission time,vehicle speed and the number of broken links,and selects the optimist infrastructures with minimum similar-distance value as the next basic communication facility for data transmission to recuce running time.The simulation results show that,compared with the EM-AODV and EN-AODV routing protocols,the proposed routing protocol can significantly reduce the average end-to-end transmission delay and average response time delay of reply messages,and improves the efficiency for dealing with emergencies.

Key words: Vehicular Ad Hoc Network(VANET), routing protocol, emergency vehicle, transmission delay, adaptive selection
