提出了一种基于IPv6的车载自组网移动切换方案MHVA。在MHVA中，车辆由其归属IPv6地址唯一标识，并且在移动过程中，车辆可以在没有转交地址的情况下与其他节点保持通信。此外，MHVA采用高级移动性切换机制，其中在网络层中的移动性切换操作在链路层中的移动性切换操作被执行之前被完成。因此，在高级移动性切换过程期间，车辆可以在链路层中保持与其当前关联的AP的连接，因此其可以接收由AP转发的数据。因此，降低了丢包率，降低了移动性切换成本，缩短了移动性切换延迟。从理论和仿真两个角度对MHVA的性能参数进行了评估，数据结果表明MHVA的移动切换代价较低，移动切换时延较短。
The paper proposes a mobility handover scheme MHVA for IPv6-based vehicular ad hoc networks. In MHVA, a vehicle is uniquely identified by its home IPv6 address, and it can keep the communication with other nodes without a care-of address during the mobility process. In addition, MHVA adopts an advanced mobility handover mechanism where the mobility handover operation in the network layer is completed before the one in the link layer is performed. As a result, during the advanced mobility handover process, a vehicle can keep the connection with its current associated AP in the link layer, so it can receive the data forwarded by the AP. Therefore, the packet loss rate is reduced, the mobility handover cost is decreased, and the mobility handover delay is shortened. From both the theoretical perspective and simulative perspective, the performance parameters of MHVA are evaluated, and the data results show that the mobility handover cost of MHVA is lower and the mobility handover delay is shorter.
