集成车载自组织网络（VANET）和通用移动通信系统（UMTS）可能是未来机器对机器应用的一个有前途的架构。这种集成可以帮助车辆通过UMTS网络获得稳定的互联网连接，并与其他车辆进行通信。然而，车辆高速行驶造成的盲区和不成功的切换过程可能会破坏这种架构的实现。在VANET - UMTS集成网络中，提出了一种简化的多跳中继网关选择方案。拟议的方案扩大了覆盖范围或/并缓和了频繁的切换过程，并允许车辆继续连接到UMTS基础设施网络。利用VanetMobiSim和NS2相结合的集成仿真环境对该方案进行了仿真和评估。仿真结果表明，在需求距离矢量路由协议和目的地顺序距离矢量路由协议下，采用ad hoc协议实现的SGS方案具有更好的性能。此外，还将SGS方案与先前工作中使用的其他基于集群的网关选择进行了比较。结果表明，我们的SGS方案在选择延迟、控制数据包开销、数据包传送率和总体吞吐量方面优于其他基于集群的网关选择方案。版权所有©2013 John Wiley & Sons， Ltd
Integrating vehicular ad hoc network (VANET) and universal mobile telecommunication system (UMTS) could be a promising architecture for future machine‐to‐machine applications. This integration can help vehicles have steady Internet connection through the UMTS network and in communicating with other vehicles. However, dead spot areas and unsuccessful handoff processes caused by the high speed of vehicles can disrupt the implementation of this kind of architecture. In this paper, a new simplified gateway selection (SGS) scheme for multihop relay in a VANET‐UMTS integration network is proposed. The proposed scheme extends the coverage or/and calming of the frequent handoff process and allows vehicles to continue to be connected to the UMTS infrastructure network. An integrated simulation environment that combines VanetMobiSim and NS2 is used to simulate and evaluate the proposed scheme. The simulation results show that the SGS scheme performed better when it was implemented with ad hoc on a demand distance vector routing and destination‐sequenced distance vector routing protocols. Furthermore, the SGS scheme is compared with other cluster‐based gateway selections used in the previous works. The results show that our SGS scheme outperforms other cluster‐based gateway selections scheme in terms of selection delay, control packet overhead, packet delivery ratio, and overall throughput.
