【摘要】:针对城市场景下车辆多、移动速度快、道路拓扑结构固定导致VANET路由协议通信性能很大下降的问题,提出一种适用于城市场景的基于地理位置的跨层多跳路由协议(city cross-layer multi-hop geography routing,CCMGR)。该协议综合考虑车辆的移动信息和物理层、数据链路层的跨层信息作为数据转发的权值,提出节点选取算法和权重决策方法动态选择权值小的节点进行数据的转发。基于NS-3网络仿真表明,CCMGR路由协议在数据传输成功率和端到端平均延迟性能方面优于GPSR、DSDV、OLSR和DSR协议,适合城市VANETs。
[Abstract]:Aiming at the problem that there are more vehicles, faster moving speed and fixed road topology in urban scenarios, the communication performance of VANET routing protocol is greatly degraded. A city cross-layer multi-hop geography routing protocol (city cross-layer multi-hop geography routing CCMGR) based on geographical location is proposed for urban scenarios. The protocol synthetically considers the mobile information and physical layer of the vehicle and the cross-layer information of the data link layer as the weight of data forwarding. The node selection algorithm and the weight decision method are proposed to transmit the data to nodes with small dynamic selection value. Simulation results based on NS-3 network show that the CCMGR routing protocol is superior to the GPSR-DSDV OLSR and DSR protocols in data transmission success rate and end-to-end average delay performance, and is suitable for urban VANETs.
