基于按需距离矢量修正的车联网稳定路由
|
摘要
车辆的高速移动以及城市场景中的障碍物使得车辆间的通信路径变得异常脆弱。为此,提出基于路径判据的按需距离矢量(AODV)的路由算法(PA-AODV),进而增强路径的稳定性。PA-AODV路由首先计算路径质量因子、移动方向因子,然后再计算路径判据权值,最后择优选择权重小路径传输数据。仿真结果表明,提出的PA-AODV路由提高了数据包传递率,并降低了端到端传输时延。
The high-speed mobility of vehicles and obstacles existing in urban area make the communication path between vehicles unreliable. Therefore,the path weight based Ad Hoc on-demand distance vector(PA-AODV) routing algorithm is proposed to enhance the path stability. In PA-AODV routing,the path quality factor and moving direction factor are computed,then the weight of path criterion is calculated,and the transmission data with light path weight is selected optimally. The simulation results show that the PA-AODV routing can improve the packet transfer ratio,and shorten the end-to-end transmission delay.
