| 摘 要： | 车载自组织网络中节点的高速移动性使得网络拓扑频繁变化，造成路由效率低下.本文提出了一种面向高速路车联网场景的自适应路由方法.本方法采用了贪婪机会转发（GOF）算法，在选择下一跳转发节点时，同时考虑到目的节点的距离计算、节点间的链路状态以及下一跳的有效节点度状况来找出最优转发节点，并提出新的计算连通概率的方法.仿真实验和实际道路场景的测试表明，与相关算法相比在路由稳定性方面表现出较好的效果.

| Abstract: | The high-speed mobility of the nodes makes the network topology change frequently,and the transmission path can be easily interrupted,so the routing efficiency is lower in Vehicular ad hoc network (VANET).We present an adaptive routing method for high-speed-road scenario of the Internet of Vehicle in this paper.This method uses Greedy Opportunity Forwarding (GOF) algorithm to find the optimal forwarding node when the next hop forwarding node is selected and it takes into account the distance calculation of the destination node,the link state between the nodes and the effective node degree of the next hop.We propose a new method to calculate the probability of connectivity.The simulation results and tests of the actual high-speed-road scenario show that our RAR method has good performance in the stability of routing,which is compared with the relative algorithms. |
