车载网络WAVE中车与车之间能够通信靠的是移动过程中车与车之间建立起来的网络连接,路由是实现网络连接的一个关键问题。基于行车速度与距离的快速多跳路由算法FMHR是以中间车辆与目标车辆之间通信时间值最小为策略来选择信息传递的下一跳。提出的保持最大通信时间KMCT路由算法与FMHR不同,KMCT是以中间车辆与发送信息车辆之间通信时间的最大值为策略来选择信息传递的下一跳,实验结果表明,当车辆速度较高时,KMCT性能要优于FMHR。
Car network WAVE in the car and the car can communicate between the car and the car is set up during the mobile network connection, routing is a key issue to achieve network connectivity. A fast multi-hop routing algorithm based on traffic speed and distance FMHR is the next hop to select the message delivery based on the strategy of minimizing the communication time between the intermediate vehicle and the target vehicle. The KMCT routing algorithm proposed in this paper is different from FMHR. KMCT chooses the next hop of information transmission based on the maximum communication time between the intermediate vehicle and the sending vehicle. The experimental results show that when the vehicle speed is high , KMCT performance is better than FMHR.
