智能交通系统(ITSS)在智能城市平台下重塑交通，走向更安全的道路、无缝物流和面向数字商业的服务方面发挥了重要作用。毫无疑问，它的应用将需要稳定的路由协议，这些协议不仅专注于车辆间通信，而且还致力于为基础设施提供快速、可靠和安全的接口。在本文中，我们提出了一种新的稳定的基于基础设施的城市VANET路由协议。它使车辆能够主动保持通往路旁单位(RSU)的新路线，同时主动发现通往附近车辆的路线。它使用一种新的交叉口稳定性度量的选择策略，从高度稳定的连通交叉口建立路线。使用精确的移动和传播模型进行的仿真实验证实了新协议的有效性和对城市环境中不断变化的网络状态的适应性。
Intelligent Transportation Systems (ITSs) have been instrumental in reshaping transportation towards safer roads, seamless logistics, and digital business-oriented services under the umbrella of smart city platforms. Undoubtedly, ITS applications will demand stable routing protocols that not only focus on Inter-Vehicle Communications but also on providing a fast, reliable and secure interface to the infrastructure. In this paper, we propose a novel stable infrastructure-based routing protocol for urban VANETs. It enables vehicles proactively to maintain fresh routes towards Road-Side Units (RSUs) while reactively discovering routes to nearby vehicles. It builds routes from highly stable connected intersections using a selection policy which uses a new intersection stability metric. Simulation experiments performed with accurate mobility and propagation models have confirmed the efficiency of the new protocol and its adaptability to continuously changing network status in the urban environment.
