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).

Robust Communication in Vehicular Ad Hoc Networks

Book Description
The development of intelligent transportation systems is one of the most important strategies for making roads safer and more efficient. The key technology underpinning all such systems, from cooperative safety systems to electronic tolling, is wireless communications. Vehicles must be able to communicate with each other, and with fixed infrastructure, in real time. One promising architecture involves forming an ad hoc network among the vehicles and taking advantage of the peer-to-peer connectivity to reduce infrastructure costs. In this dissertation, we consider the design and analysis of medium access control and network layer protocols for vehicular ad hoc networks. In particular, we examine the problem of distributing content over many hops from a source to a destination. The fundamental challenge in such systems is the inability of the vehicles to coordinate with each other. Because of the high frequency at which vehicles enter and exit the road, and the fact that vehicles may be moving at widely varying speeds, the topology is continuously changing. Therefore, centralized scheduling of transmissions to avoid collisions and global routing of packets is either technically infeasible or prohibitively expensive. We propose instead a class of uncoordinated protocols, based on randomized channel access and network coding. The key idea behind the coding is for the vehicles to transmit random combinations of all the packets that they have received, instead of simply forwarding packets. This scheme does not require link level feedback, and thus vehicles do not need to track the identities of their current neighbors. We first consider a minimally coordinated protocol, where the vehicles on a road are partitioned into spatial blocks. The block structure is used to funnel waves of data down the road, while the vehicles within each block randomly contend with each other for the channel. We show that when the vehicles use network coding in this scheme, the end-to-end throughput is constant, as long as the number of blocks in the network does not grow exponentially in the vehicle density. Network coding allows for the reliable transport of data over many hops at the same rate at which data could be sent over a single hop. Then we consider a completely uncoordinated protocol, which does not even require the assignment of vehicles to spatial blocks. We begin by providing a general algorithm for computing the throughput of an arbitrary network using such a protocol. The main technical contribution is to account for the fact that intermediate nodes may temporarily not have any new packets to transmit to their neighbors, due to the random channel access. We prove that the throughput of this wireless network is equal to the throughput of an equivalent wired network, despite the randomized medium access strategy. This result has application in a variety of other contexts, where it is often assumed for tractability that relays always have data when they use the channel. We then apply this result to the problem of finding the throughput in an uncoordinated vehicular ad hoc network. In a congested highway, where the connectivity graph is homogeneous, a constant throughput can be provided to receivers that are located at an arbitrary distance from the source. In essence, every vehicle can be thought of as a digital repeater, despite the packet losses due to collisions.

Book Description
This book introduces the Internet access for vehicles as well as novel communication and computing paradigms based on the Internet of vehicles. To enable efficient and reliable Internet connection for mobile vehicle users, this book first introduces analytical modelling methods for the practical vehicle-to-roadside (V2R) Internet access procedure, and employ the interworking of V2R and vehicle-to-vehicle (V2V) to improve the network performance for a variety of automotive applications. In addition, the wireless link performance between a vehicle and an Internet access station is investigated, and a machine learning based algorithm is proposed to improve the link throughout by selecting an efficient modulation and coding scheme. This book also investigates the distributed machine learning algorithms over the Internet access of vehicles. A novel broadcasting scheme is designed to intelligently adjust the training users that are involved in the iteration rounds for an asynchronous federated learning scheme, which is shown to greatly improve the training efficiency. This book conducts the fully asynchronous machine learning evaluations among vehicle users that can utilize the opportunistic V2R communication to train machine learning models. Researchers and advanced-level students who focus on vehicular networks, industrial entities for internet of vehicles providers, government agencies target on transportation system and road management will find this book useful as reference. Network device manufacturers and network operators will also want to purchase this book.

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.
