Executive Summary

Generally vehicular networks are considered to contain two types of nodes; vehicles and roadside stations. Vehicular communications is usually developed as a part of Intelligent Transport Systems (ITS) that seeks to achieve safety and productivity through intelligent transportation which integrates communication between mobile and fixed nodes.
