摘要
结合动态渗流理论对车载自组织网连通性能进行分析,利用NS2仿真平台,针对不同的车辆密度和车辆运行速度,对传统的路由协议(AODV、DSDV、DSR)进行仿真,分析了影响其网络性能的因素。研究表明,为保持连通性,需要满足一定的节点密度;与DSR和DSDV协议相比,AODV更适合于车载自组织网。
The VANET connectivity performance is analyzed using NS2 simulation platform, the traditional routing protocols with different vehicle density and vehicle speed, and the influ are analyzed. The results show that connectivity is associated with dynamic percolation theory. By （ AODV, DSDV, DSR） are simulated encing factors of network performance with the node density, and AODV is more suitable for VANET compared with DSR, and DSDV routing protocol
