摘要:

随着信息通信技术(ICT)和无线嵌入式传感设备进入现代车辆,智能交通系统(ITS)成为现实,成为智慧城市不可或缺的组成部分。ITS的目的是提高道路安全和交通效率,并提供信息服务。事实上,在正确的时间警告驾驶员道路上的危险情况,并为他们提供有关交通的先验信息,无疑会提高驾驶员的安全性,减少交通拥堵。从技术上讲,ITS是基于自组织无线网络,称为车载自组织网络(VANESTs)。在VANET中的移动车辆可以在基于基础设施的网络中扮演固定传感器的角色。它们可以检测、收集和传播有关交通、驾驶条件和道路上潜在危险的实时数据。在这方面,我们在这项研究中,最近的发展VANET协议和应用程序的设计。我们首先介绍了VAN的体系结构,然后我们回顾了它们独特的特点和应用。此后,我们讨论了主要的研究挑战和开放的问题,要考虑设计高效和具有成本效益的VANET协议和应用。

英文摘要:

With the emergence of Information and Communication Technologies (ICT) and wireless embedded sensing devices into modern vehicles, Intelligent Transport System (ITS) becomes a reality and an indispensable component of smart cities. The purpose of ITS is to improve road safety and traffic efficiency as well as offering infotainments services. In fact, warning drivers in the right time about dangerous situations on the road and providing them with prior information about traffic will undoubtedly leads to enhance driver's safety and reduce traffic congestion. Technically speaking, ITS is based on self-organizing wireless networks, known as vehicular ad-hoc networks (VANETs). Mobile vehicles in VANET might play the role of stationary sensors in infrastructure-based networks. They can detect, gather and disseminate real-time data about traffic, driving conditions and potential hazards on roads. In this respect, we review in this study, recent developments on the design of VANET protocols and applications. We first introduce the architecture of VANETs then we review their unique characteristics and applications. Thereafter, we discuss the main research challenges and open issues to be considered for designing efficient and a cost-effective VANET protocols and applications.
