Electronic Control Units (ECUs) of a vehicle control the behavior of its devices–e.g., break and engine. They communicate through the in-vehicle network. Vehicles communicate with other vehicles and Road Side Units (RSUs) through Vehicular Ad-hoc Ne
随着车联网VANETs(Vehicular Ad hoc Networks)应用日益受到关注, 研究者对VANETs路由协议进行了深入研究。为此,首先总结VANETs的特点及应用,再介绍了基于位置的、基于拓扑以及基于广播路由的概念,并着重分析和总结了近期路由协议的核心思想以及特点,此外,还从应用场景、前提条件、虚拟设备要求、电子地图需求、路由恢复策略以及转发模式六个方面对路由协议进行全面比较,最后,展望了VANETs路由技术的未来研究方向。
Nowadays, message propagation has been one of the major tasks of Vehicular Ad-Hoc Networks (VANETs).The main obstacle of message propagation, which relies on the data forwarding among vehicles, is the frequent change innetwork topology, as the interm
The mobility of mobile nodes is a distinctly important influence factor for video sharing performance, user quality of experience and traffic load remission of core networks in vehicular ad hoc networks (VANETs). In this paper, we propose a novel mo
In this paper, we address the low efficiency of cluster-based communication for the crossroad scenario in VANETs, which is due to the overload of the cluster head resulting from a large number of transmission bandwidth requirements. We model this iss
在车载自组织VANETs中,为解决车辆间通信数据传输不流畅的问题。提出采用3G辅助VANETs的数据传输技术。在无法利用VANETs多跳通信传输数据时,启动3G传输,将此方案命名为3GDD,首先建立数据传输率和数据传输时延的效用函数,利用3G辅助VANETs数据传输实现最大化效用;其次,为了避开优化问题的复杂性,将原始的优化问题变换成整数线性规范问题ILP(integer linear programming problem);最后通过解决ILP,在不同时刻分配3G预算,并选择最不可能通过VAN
