This book illustrates their benefits and real-life applications. It examines possible services that these networks can provide and presents their possible deployment architectures, while also showing the roles of the involved contributors (networks operators, car manufacturers, service providers, and governmental authorities). The book explores the technical challenges in deployment, such as MAC protocols, routing, information dissemination, dynamic IP auto configuration, mobility management, security, and the privacy of drivers and passengers. In addition, it considers the possible business models for deploying such networks. Vehicular networks have special behavior and characteristics, distinguishing them from other types of mobile networks.
