Recently, Vehicular Ad hoc Networks (VANETs) have achieved widespread applicability in different application domains related to transportation systems such as providing public safety and assistance, driving improvement, toll collection, roadside service finders, traffic monitoring and control, highway Internet access and enhancing safety and efficiency of highway systems. VANETs are also known as Wireless Access in Vehicular Environment (WAVE) that supports Intelligent Transportation Systems (ITS) through Dedicated Short-Range Communication (DSRC). In VANETs, there are two types of communications: vehicle to vehicle (V2V) and vehicle to infrastructure (V2I). Vehicles have On Board Units (OBUs), which consist of Omni directional antennas, processors, GPS unit, and sensors for V2V communications.Vehicles also perform V2I communications with roadside infrastructures, which are placed within a fixed distance of each other depending upon the communication range of the roadside devices, also known as Road Side Units (RSUs). RSUs communicate each other through wireless medium or wired connections.
