Vehicular Ad-Hoc Network: Current Challenges_2
IntroductionWith the increase in the technological advancements and the decrease in the costs of electronic components, the manufacturers have oriented towards introducing new things in their vehicles. One such component is the Vehicular Ad-hoc Network (VANet). Now the manufacturers are moving faster towards building vehicles that can communicate with each other on the road and become automated or, in other word, driver less (Raya & Hubaux, 2005). Various initiatives are being taken to consider the introduction of VANET based vehicles for the actual passengers. However, it has been observed that this technology is facing multiple challenges in terms of security. These security challenges are making the instant application of this technology less plausible (Junyuan et al, 2007). The vehicular communication brings huge opportunity 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 the vehicular ad-hoc network to understand whether the system can be implemented for the general public. Moreover, the focus will be to gain brief understanding of this technology along with the various security challenges posed by it.The paper has been divided into three key sections. The first is the background, where the focus would be to understand the technology in brief and the need for the study. The second section is focused on understanding the problems associated with the security aspects of VANET. The third section is concerned with understanding whether there are ways to handle the security challenges and make the system implementable for the masses.

BackgroundVANET is also called as intelligent transportation system. In this system the vehicles receive the information from the other vehicles or communication points on the road, sends the information and 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 that all 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, and another is On-Board Unit. These two units and the OBUs of the other vehicles together form an ad hoc network (Kudoh, 2004). Also it is required that the vehicles have global positioning system installed to track its actual location. The road side units can be placed at specific distance to 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 highly accurate and reliable. During the communication with the other vehicles, the multi-hop broadcasting is used for the transmission of the information that is associated with the traffic to the 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 from the vehicle. There are two forms of broadcasting of the information that takes place in the VANET (Festag, 2009). The first form is called as naïve broadcasting. In this broadcasting method, the vehicle regularly sends all the communication on the regular basis to the various receivers under its range.
