Vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communications and cooperative driving

Abstract

Cooperative vehicle to infrastructure and vehicle to vehicle safety and mobility applications are described. Applications are separated into static and dynamic categories, such as fixed roadway hazards versus changing traffic signals. Communications requirements are discussed in the context of overall application functional requirements including the specific safe distances required for driver to react to alerts and warnings and to take appropriate action. These requirements are translated into conventional link budget terms relative to those that affect communication reliability such as a transmitter power and receiver sensitivity, multipath fading, and overall channel capacity. The implications of networked transmissions versus broadcast, non-network transmissions are discussed in the context of safety applications.
