The topics addressed in this book are crucial for both the academic community and industry, since the vehicular network has become an essential building block for intelligent transportation systems. The systematic principle of this book provides valuable guidance on the deployment and implementation of V2X-enabled road-safety applications. In addition, this book carries out structured technologies from the MAC layer to the link and network layer, which can provide a general introduction for interested readers with a comprehensive understanding of applying vehicular networks in enhancing road safety, and offers a systematized view for researchers and practitioners in the field of vehicular networks to help them optimize and improve the desired vehicular communication systems. Road safety has always been the first priority for daily commuters on the road. Vehicular networks can be an effective solution to enhance road safety, via which vehicles can exchange cooperative awareness messages rapidly, contributing to better situation awareness and maneuvering cooperation. However, with the fast-changing network topology, intermittent wireless link, and dynamic traffic density, it is challenging to achieve satisfying network performance. This book introduces the background of vehicular networks, provides a comprehensive overview of networking techniques in supporting road-safety applications, states the technical motivations per the MAC, link, and network layer, and proposes/designs vehicular networking technologies at the corresponding layer respectively to guarantee low-latency and reliable V2X communications for road-safety applications. By extending the proposed networking technologies to support all types of vehicular services, this book also outlines open issues and research directions in future 5G and beyond vehicular networks....

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....

Vehicles that talk to each other are expected to unleash a broad spectrum of applications that will make road travel safer, faster, efficient and more entertaining. We study safety messaging, which enables applications that provide different levels of driver assistance to improve on-road safety, for different vehicular network scenarios. Initial deployments of safety applications in vehicles are expected to be sparse with support for event-driven messaging over a few wireless hops, for example, a car broadcasting messages when in distress. We propose GeoMAC, a protocol that exploits spatial diversity of forwarder nodes, and a geo-backoff mechanism to resolve contention between them, and achieves message delivery with smaller latency and jitter, and greater reliability. Eventually, all on-road vehicles will broadcast their state information, such as location and velocity, many times a second. Each vehicle's state must be received in a timely manner and be refreshed periodically at all other vehicles of interest. The network objective of minimizing the system age, which we define, is then explored for single and multi-hop networks. For single-hop networks we assume a carrier-sense-multiple-access (CSMA) based sharing of the wireless medium. We show that the minimum system age cannot be achieved in 802.11 networks through pure MAC techniques. We propose, and evaluate on ORBIT, an application broadcast rate adaptation algorithm that allows nodes to locally adapt their messaging rate to keep the system age to a minimum. Next, we explore the benefits of a multi-hop wireless connectivity for a given physical network of on-road vehicles, when nodes can piggyback other nodes' states. The system age optimization is formulated for arbitrary network graphs and round robin schedules. We show that, under certain conditions, significant improvements in system age may be obtained. For tree topologies, an algorithm that gives schedules that minimize system age is proposed. We end our study on messaging with an empirical evaluation of how enabling location prediction can help reduce rate of messaging and hence channel congestion. Finally, we measure and model the effect of a car's own geometry, antenna placement, and of other cars in vicinity, on the vehicle-to-vehicle link and the network....

Over the last few years vehicular networks have been receiving a lot of attention from academia, industry, standardization bodies, and the various transportation agencies and departments of many governments around the world. It is envisaged in the next decade that the Intelligent Transportation System (ITS) will become an essential part of our daily life. This book describes models and/or algorithms designed to investigate evolutionary solutions to overcome important issues such as congestion control, routing, clustering, interconnection with long-term evolution (LTE) and LTE advanced cellular networks, traffic signal control and analysis of performances through simulation tools and the generation of vehicular mobility traces for network simulations. It provides an up-to-date progress report on the most significant contributions carried out by the specialized research community in the various fields concerned, in terms of models and algorithms. The proposals and new directions explored by the authors are highly original, and a rather descriptive method has been chosen, which aims at drawing up complete states of the art as well as providing an overall presentation of the personal contributions brought by the authors and clearly illustrating the advantages and limitations as well as issues for future work.

This book provides probabilistic, deterministic and geolocation-aware approaches for adaptive connectivity, robust security and privacy-aware communications for vehicular cyber physical systems (CPS). It presents mathematical models and numerical results obtained from experiments and simulations, and a trade-off between connectivity, security and privacy for vehicular communications. Connectivity between vehicles is crucial for vehicular CPS. Intelligent vehicular CPS provides not only road safety and traffic efficiency by exchanging information among vehicles, but also offers infotainment services to passengers using a variety of wireless technologies to forward the traffic/trajectory information with Vehicle-to-Vehicle (V2V), vehicular ad hoc network (VANET), and Vehicle-to-Roadside-to-Vehicle (V2R2V) communications. The book covers how to ensure that the message received from other vehicles is secure and trustworthy, rather than malicious. Further, it reveals how to make sure that the privacy of participants is not revealed while validating the received message. Researchers and professionals working with vehicular networks, smart systems, cyber physical systems, and mobile privacy will find this book valuable....
