城市环境下跨层VANET路由协议研究
发布时间：2018-07-21 15:11
【摘要】：车载自组织网络(VANET)单一分层结构路由协议考虑因素较少,导致分组投递率低、端到端时延较高。为此,考虑车辆位置、速度、路口密度、无线链路质量、MAC层误帧率等影响因素,提出一种应用于城市环境的基于位置信息的VANET跨层路由协议(MCLPR)。设计路口车辆节点选择算法提取无线链路质量和MAC层误帧率的跨层信息,采用层次分析法计算各影响因素的权重值,确定最佳转发路径。仿真结果表明,与AODV,DSDV等路由协议相比,MCLPR路由协议具有较高的分组投递率及较低的端到端时延,保证了数据传输的可靠性与高效性,适用于网络密度与负载较大、车辆移动速度较快的城市环境。
[Abstract]:The single layered routing protocol in vehicle Ad Hoc Networks (VANET) takes less factors into account, which leads to low packet delivery rate and high end-to-end delay. Therefore, considering the influence factors such as vehicle location, speed, intersection density, wireless link quality and MAC layer frame error rate, a VANET cross-layer routing protocol (MCLPR) based on location information is proposed for urban environments. A vehicle node selection algorithm is designed to extract the cross-layer information of wireless link quality and MAC layer frame error rate. The weight of each factor is calculated by AHP and the optimal forwarding path is determined. The simulation results show that the MCLPR routing protocol has higher packet delivery rate and lower end-to-end delay compared with AODVO DSDV and other routing protocols, which ensures the reliability and efficiency of data transmission, and is suitable for high network density and load. Urban environment where vehicles move faster.
