车辆间通信可以成为ITS远程信息处理应用（如安全和警告功能）的重要组成部分。移动的自组织网络（MANET）可以用作本地无线网络，用于在汽车之间交换信息以用于协作驾驶员辅助应用。对于这种由道路上的车辆组成的大规模移动自组网中的数据包路由，地理多跳分组转发是一种很有前途的方法。然而，一个主要的缺点是，它表现不佳的网络中有许多拓扑漏洞。在本文中，我们提出了一个空间感知的数据包路由方法来预测永久的拓扑空洞所造成的空间限制，并事先避免它们。这种方法是通用的，并且可以与任何现有的地理转发协议结合使用作为扩展。我们的模拟表明，空间感知可以显着提高地理转发性能的情况下，许多永久的拓扑漏洞，如在动态车辆网络。
Inter-vehicle communication can become an important building block for ITS telematics applications like safety and warning functions. Mobile ad hoc networks (MANETs) can serve as a local wireless network for exchanging information between cars for cooperative driver assistance applications. For the routing of data packets in such large-scale MANETs consisting of vehicles on the road, geographic multi-hop packet forwarding is a promising approach. However, a main drawback is that it performs poorly in networks with many topology holes. In this paper, we propose a spatially aware packet routing approach to predict permanent topology holes caused by spatial constraints and avoid them beforehand. This approach is generic and can be used in combination with any existing geographic forwarding protocol as an extension. Our simulations demonstrate that spatial awareness can significantly improve geographic forwarding performance in situations with many permanent topology holes, like in dynamic vehicle networks.
