Book Description
Safety-critical, safety and non-safety related Vehicular Ad hoc Network (VANET) messages have localized spatial scope. These messages have also limited time relevance in the vehicular network. A vehicular communication protocol set must ensure timely delivery of such messages with high reliability over a shared wireless medium. The vehicles moving on the road form a fluid straitjacketed topology. In this work, a vehicular communication protocol is proposed to minimize channel allocation time and management overhead in the vehicular networks. Moreover, a time slot is allotted to a vehicle in accordance with the priority of the request and availability of the channel. This communication protocol indicates that the allocation scheme is able to deliver packets within the stipulated time with high reliability for different vehicle speeds and density for channel allocation. Furthermore, the technique does not suffer from the hidden and exposed node problem during vehicular communication.

Book Description
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.

Book Description
What Is Vehicular Communication Systems Computer networks known as vehicular communication systems consist of communicating nodes located in cars and roadside devices. These nodes share information with one another, including safety alerts and traffic data, as part of the network. They have the potential to be useful in reducing the occurrence of accidents and alleviating congestion. Each kind of node is a device that is intended only for use in dedicated short-range communications (DSRC). The DSRC operates in the 5.9 GHz band and has a bandwidth of 75 MHz. Its range is about 300 meters (980 ft). Intelligent transportation systems often include the development of vehicular communications as one of its components (ITS).

Book Description
Universal vehicular communication promises many improvements in terms of ac- dent avoidance and mitigation, better utilization of roads and resources such as time and fuel, and new opportunities for infotainment applications. However, before widespread acceptance, vehicular communication must meet challenges comparable to the trouble and disbelief that accompanied the introduction of traf c lights back then. The rst traf c light was installed in 1868 in London to signal railway, but only later, in 1912, was invented the rst red-green electric traf c light. And roughly 50 years after the rst traf c light, in 1920, the rst four-way traf c signal comparable to our today’s traf c lights was introduced. The introduction of traf c signals was necessary after automobiles soon became prevalent once the rst car in history, actually a wooden motorcycle, was constructed in 1885. Soon, the scene became complicated, requiring the introduction of the “right-of-way” philosophy and later on the very rst traf c light. In the same way the traf c light was a necessary mean to regulate the beginning of the automotive life and to protect drivers, passengers, as well as pedestrians and other inhabitants of the road infrastructure, vehicular communication is necessary to accommodate the further growth of traf c volume and to signi cantly reduce the number of accidents.

Book Description
Vehicles are an integral part of modern life. People depend on vehicles for transportation between work, home, and entertainment. As populations have grown and lower production costs have made vehicle ownership more accessible to more people, the number of vehicles on the road has skyrocketed. The potential for a collision with other drivers increases as more vehicles are added to the roadways. These additional vehicles also create congestion, consuming drivers' valuable time, and contributing to traffic delays. Huge advances have been made in technology since the introduction of the first vehicle at the turn of the 20th century. Modern vehicles are equipped with sensors, navigation systems, and communication devices that enable data collection and information sharing like never before. This technology can be leveraged to improve traffic efficiency and safety. The first contribution of this dissertation is the introduction of a framework that uses historical and real-time traffic data to access the risk levels of various routes to provide drivers with the ability to consider their safety when making travel plans. The second contribution is a protocol that relies on cooperation between vehicles through wireless communication to improve the overall traffic state of all vehicles along a roadway. The third contribution is a scheme that reduces the load placed on cellular infrastructure that provides vehicles access to Internet content. The results in this work further the movement of vehicular technology-based solutions, creating safer and more efficient driving experiences.

Book Description
The main goal of intelligent transportation systems (ITS) is to improve traffic efficiency and mobile safety. The Dedicated Short Range Communication system (DSRC) standard based inter-vehicle communications system plays a key role in ITS [1]. In October 1999, the Federal Communications Commission (FCC) allocated the frequency spectrum between 5.850 and 5.925 GHz for DSRC, which will enable vehicles to communicate with the road infrastructure, and allows for a large number of ITS applications. This provides an opportunity for automakers, government agencies, and related commercial entities to improve highway safety. However, inter-vehicle communications must operate effectively within transmit power limits and under received signal strength uctuations and Doppler spread. Conventionally, Convolutional coding was employed for forward error correction (FEC);however, in this book, we consider DSRC performance using Low Density Parity Check (LDPC) codes and Quasi-Cyclic (QC)-LDPC codes under different channel conditions. Results show that a QC-LDPC code provide an attractive trade off between performance and complexity, and should be considered as an alternative for DSRC systems.

Book Description
Intelligent Transportation System (ITS) is the integration of advanced communication technologies into the transportation infrastructure and in vehicles. It is aimed to improve transportation safety and to enhance traffic management. Vehicular networks and traffic monitoring are two important research topics in ITS. Dedicated Short-Range Communications (DSRC) is a wireless communication standard specially designed for vehicular networks. DSRC provides traffic safety operations in vehicle-to-vehicle communications and vehicle-to-infrastructure communications with low communication latency and a long transmission rang of up to 1000 meters. Many possible applications are able to be implemented on DSRC. However, the insufficient capacity of a DSRC roadside unit limits the deployment of DSRC in cities. We propose a multi-radio DSRC scheme in this dissertation. Multi-radio technology can improve the safety characters of DSRC, and can increase DSRC bandwidth. Then we analyze and provide the antenna isolation requirement of multi-radio DSRC. The feasibility study in multi-radio DSRC will be discussed in this dissertation too. 40 percent of crashes occurred in the states were intersection-related crashes [76]. It is imperative to monitor intersections. Video cameras are deployed at main intersections for area surveillance, traffic monitoring, traffic light control, ticket issuing, crime fighting, etc. However, the hardware deployment, data transmission, data storage, and real-time data processing of each video camera cost a lot of money. Traffic cameras are only deployed at a few main intersections in most cities. We propose a low cost low data-rate pyroelectric sensing system to monitor non-camera-monitored intersections. A high dynamic signal conditioning circuit for pyroelectric sensor is implemented and tested to detect vehicles. We also propose and evaluate a hierarchical wireless mesh network structure for the pyroelectric sensing system.

Book Description
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.
