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，例如危险的早期预警、车辆交通信息以及视频流和互联网接入。车辆网络由在街道/高速公路上行驶的能够彼此通信的多个车辆（配备有一个或多个无线接口）组成。车载网络有三种可能的配置：纯无线ad-hoc网络、无线基础设施或结合两者的混合/集成架构。在公开的文献中，很少有工作被做来研究（1）车载无线基础设施的设计;事实上，大多数现有的相关研究仅考虑车辆与路边AP之间的数据传输问题;以及（2）服务质量（QoS）支持/保证支持不同类别的流量，同时考虑到车辆网络中资源的严重波动和容量变化

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.
