Abstract

Vehicular ad hoc networks (VANETs) present an intriguing platform for several applications on e.g., intelligent transportation system (ITS) and infotainment applications aspire to be the main pattern of communication among vehicles while travelling. This can significantly impact on the amount of data exchanged by vehicles, increasing the contention on communication links and thus, degrading the quality of service of these applications. So, discrimination of data becomes imperative and forwarding critical information on suitable routes becomes decisive. Hence, a quality of service (QoS)-driven mechanism is needed to handle and assign network resources according to the stringent application data traffic demands. But, VANETs high node mobility and frequent link failure, stuck a big challenge in implementing an effective policy to meet and enforce these QoS requirements. A promising way to tackle this issue is to enforce QoS at the network layer, since it is the crucial point in VANETs’ communication. So, over the years, many QoS-aware routing protocols were specifically conceived for VANETs. In this paper, we present a comprehensive survey of QoS-aware routing protocols in VANETs’ literature. We examined the protocols based on their ability to support ITS infotainment services, their multi-constraint path problem (MCP), protocol’s functionality and weakness, objectives and design challenges. This way, we outline future directions for VANETs QoS-aware protocol research.

基于VANET的基于QoS的路由协议,该协议基于支持ITS信息娱乐服务的多约束能力

摘要

车载自组织网络(VANET)为智能交通系统(ITS)和信息娱乐应用等多种应用提供了一个有趣的平台,希望成为行进途中车辆之间通信的主要模式。这会严重影响车辆交换的数据量,增加对通信链路的争用,从而降低这些应用程序的服务质量。因此,区分数据变得势在必行,并且在适当的路由上转发关键信息变得至关重要。因此,需要一种服务质量(QoS)驱动的机制来根据严格的应用程序数据流量需求来处理和分配网络资源。但是,VANET具有高节点移动性和频繁的链路故障,在实施有效的策略来满足和执行这些QoS要求方面遇到了巨大挑战。解决此问题的一种有前途的方法是在网络层上实施QoS,因为这是VANET通信的关键点。因此,多年来,专门为VANET设计了许多QoS感知路由协议。在本文中,我们对VANET文献中的QoS感知路由协议进行了全面的调查。我们根据协议支持ITS信息娱乐服务的能力,多约束路径问题(MCP),协议的功能和弱点,目标和设计挑战来检查协议。这样,我们概述了VANET QoS感知协议研究的未来方向。因为这是VANET通信的关键点。因此,多年来,专门为VANET设计了许多QoS感知路由协议。在本文中,我们对VANET文献中的QoS感知路由协议进行了全面的调查。我们基于支持ITS信息娱乐服务的能力,多约束路径问题(MCP),协议的功能和弱点,目标和设计挑战,对协议进行了检查。这样,我们概述了VANET QoS感知协议研究的未来方向。因为这是VANET通信的关键点。因此,多年来,专门为VANET设计了许多QoS感知路由协议。在本文中,我们对VANET文献中的QoS感知路由协议进行了全面的调查。我们根据协议支持ITS信息娱乐服务的能力,多约束路径问题(MCP),协议的功能和弱点,目标和设计挑战来检查协议。这样,我们概述了VANET QoS感知协议研究的未来方向。他们的多约束路径问题(MCP),协议的功能和弱点,目标和设计挑战。这样,我们概述了VANET QoS感知协议研究的未来方向。他们的多约束路径问题(MCP),协议的功能和弱点,目标和设计挑战。这样,我们概述了VANET QoS感知协议研究的未来方向。
