Resources management in vehicular networks

车载网络技术的进步使新的安全、信息和娱乐应用成为可能，例如危险早期预警、车辆交通信息以及视频流和互联网接入。车载网络由在街道/高速公路上行驶的多辆车(配备了一个或多个无线接口)组成，能够相互通信。车载网络有三种可能的配置：纯无线自组织网络、无线基础设施或结合两者的混合/集成架构。在公开文献中，很少有人研究(1)车载无线基础设施的设计；事实上，现有的大多数相关研究只考虑了车辆和路边AP之间的数据传输问题；以及(2)在考虑车载网络资源的剧烈波动和瞬时容量变化的同时，支持/保证服务质量(Qos)以支持不同类别的流量。

Advances in vehicular networking technology enable novel safety, information, and entertainment applications, such as early warning of hazards, vehicular traffic information, and video streaming and Internet access. Vehicular networks consist of a number of vehicles (equipped with one or more wireless interfaces) traveling on streets/highways, capable of communicating with each other. There are three possible configurations of vehicular networks: a pure wireless ad-hoc network, wireless infrastructure, or a hybrid/integrated architecture combining the two. In the open literature, little work has been done to investigate (1) the design of the vehicular wireless infrastructure; indeed, most existing related research considers only the problem of transmitting data between vehicles and roadside APs; and (2) Quality of Service (QoS) support/assurance to support different classes of traffic while taking into account the severe fluctuation of resources in vehicular networks and the instantaneous capacity variation.
