服务车际通信的混合网络系统

A hybrid network for Inter-vehicle-Communication

提出了一种VANET与UMTS相结合的混合网络系统,在VANET的网络拓扑结构不完整时,它可以有效地解决通信畅通的问题.它借助UMTS覆盖面广和Ad hoc Networks结构灵活的特点,通过在不同网络接口间的切换从而实现了车际间不间断通信.

The paper proposed a hybrid network, which combines VANET and UMTS networks, when communication link is broken in the VANET, hybrid networks would efficiently provide communication link. Utilizing the characteristics of UMTS of wide coverage and flexible structural of Ad hoc Networks, the uninterrupted communication between vehicles through handoff between the different network interfaces has been realized.
