IntroductionWith the increase in the technological advancements and the decrease in the costs of electroniccomponents, the manufacturers have oriented towards introducing new things in their vehicles.One such component is the Vehicular Ad-hoc Network (VANet). Now the manufacturers aremoving faster towards building vehicles that can communicate with each other on the road andbecome automated or, in other word, driver less (Raya & Hubaux, 2005).Various initiatives are being taken to consider the introduction of VANET based vehicles for theactual passengers. However, it has been observed that this technology is facing multiplechallenges in terms of security. These security challenges are making the instant application ofthis technology less plausible (Junyuan et al, 2007). The vehicular communication brings hugeopportunity in terms of increase in the safety, reduction in traffic, reduction in the road accidents,and others (Harsch et al, 2007).The current paper is concerned with investigating the various aspects associated with thevehicular ad-hoc network to understand whether the system can be implemented for the generalpublic. Moreover, the focus will be to gain brief understanding of this technology along with thevarious security challenges posed by it.The paper has been divided into three key sections. The first is the background, where the focuswould be to understand the technology in brief and the need for the study. The second section isfocused on understanding the problems associated with the security aspects of VANET. Thethird section is concerned with understanding whether there are ways to handle the securitychallenges and make the system implementable for the masses.
BackgroundVANET is also called as intelligent transportation system. In this system the vehicles receive theinformation from the other vehicles or communication points on the road, sends the informationand also acts as the router (Stampoulis & Chai, 2007). The information is used by all the vehiclesin a network to ensure that the movement of vehicle is handled appropriately. It is necessary thatall the vehicles have the radio installed on it for easy communication with the road side units(Balon, 2006).There are two types of units necessary to form the communication, one is Road-Side Unit, andanother is On-Board Unit. These two units and the OBUs of the other vehicles together form anad hoc network (Kudoh, 2004). Also it is required that the vehicles have global positioningsystem installed to track its actual location. The road side units can be placed at specific distanceto each other depending on the requirement of the communication with the vehicles (Yin et al,2004).For smooth transportation, it is important that the network communication is instant and highlyaccurate and reliable. During the communication with the other vehicles, the multi-hopbroadcasting is used for the transmission of the information that is associated with the traffic tothe various receivers in the network (Jiang & Delgrossi, 2008.The vehicle needs to be concerned with what is in the front of it and receiving information fromthe vehicle. There are two forms of broadcasting of the information that takes place in theVANET (Festag, 2009). The first form is called as naïve broadcasting. In this broadcastingmethod, the vehicle regularly sends all the communication on the regular basis to the variousreceivers under its range.
