The sharp increase of vehicles in recent years has made driving more challenging and dangerous. For safe driving, leading car manufacturers have been jointly working with national government agencies to develop solutions to help drivers anticipate hazardous events and avoid traffic jams. One of the recent outcomes is a novel wireless architecture called wireless access for the vehicular environment (WAVE) that provides short-range intervehicular communications to enable fast dissemination of emergency related messages. To reap the benefits of inter-vehicle communication in a short time with minimal investment, use of vehicular ad hoc networks (VANETs) is envisioned.
