Exchanging information among vehicles is one of the key technological enablers to support foresighted driving, thus making traffic, in total, safer, more comfortable, and more efficient. In order to make the vision of a widespread intervehicle network come true, where arbitrary data can be transfered among nodes and reliably disseminated within certain geographical regions with low latency, a number of technological challenges have to be solved. This chapter gives an overview on those challenges and presents various approaches with respect to data dissemination in vehicular networks. In particular, an integrated approach is presented that explicitly aims to maximize the overall network utility in all traffic situations and thereby seamlessly scale between high and low traffic densities. Book Synopsis: Vehicular networks have special behavior and characteristics, distinguishing them from other types of mobile networks. 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 autoconfiguration, mobility management, security, and the privacy of drivers and passengers. In addition, it considers the possible business models for deploying such networks.
