Über dieses Buch

This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature.A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle-to-infrastructure communications.This book offers useful insights into protocol design and inspires a new line of thinking in performance improvements for safety applications in vehicular networks. It is a valuable resource for professionals, researchers, or advanced-level students working in vehicular networks or quality of service.

Chapter 1. Introduction
Abstract
With the ever-rapid development of the wireless communication technology, vehicular networks have been emerging as one of the most promising solutions to reduce vehicle accidents and improve traffic efficiency in intelligent transportation systems (ITS). Catering to the aforementioned demands, safety-related information about an accident, blocked streets, and traffic congestion, should be quickly broadcast to nearby vehicles by either vehicle-to-vehicle (V2V) communications or vehicle-to-infrastructure (V2I) communications. As a result, the design of an efficient broadcast protocol has become a relatively nascent research field in vehicular networks recently.

Chapter 2. Overview of Safety Message Broadcast in Vehicular Networks
Abstract
In vehicular networks, safety-related applications usually operate based on wireless broadcast since warning messages (e.g., accident, blocked street, traffic congestion, etc.) need to be delivered to all nearby vehicles. Sometimes vehicles that have detected emergency events only need to broadcast the emergency messages to nearby vehicles within the transmission coverage, and a single-hop packet broadcast may be acceptable for this type of applications. In such a case, the MAC protocol will become the dominant component that determines the transmission efficiency of an emergency message.

Chapter 3. Cross-Layer Broadcast in V2V Communication Networks
Abstract
Broadcast transmissions in inter-vehicle communications are usually confronted with fundamental challenges that greatly degrade the network performance. To this end, we firstly design a novel metric for selecting a proper relaying node to forward the emergency message. Based on the derived metric, we propose a cross-layer approach to efficiently broadcast emergency messages in the desired propagation direction. We analyze the network performance in terms of the packet error rate of the emergency message, relay selection delay, and emergency message access delay.

Chapter 4. Urban Multi-hop Broadcast in V2V Communication Networks
Abstract
In VANETs, multi-hop wireless broadcast has been considered as a promising technology to support safety-related applications that have strict QoS requirements, such as low latency, high reliability, scalability, etc.

Chapter 5. Safety Message Dissemination in V2I Communication Networks
Abstract
Vehicular networks are targeted to provide efficient communications between mobile vehicles and fixed RSU, and support mobile multimedia applications and safety services with diverse QoS requirements. In this chapter, we propose a busy tone based MAC protocol with enhanced QoS provisioning for life-critical safety services.
