Security Challenges in VANET: A Comprehensive Survey_1

VEHICULA AD-HOC NETWORKAbstractVehicular Ad-hoc Network (VANET) is considered as the subclass of the mobile ad hoc networks (MANETs) and is considered as the promising approach in case of intelligent transportation system (ITS). The aim of VANET is to insure safe drive through improvement of the traffic flow as well as it is expected for decreasing the car accidents with a great number. However, providing proper security together with privacy in VANETs has been considered as the most significant issue in this field since it relies on message transmissions where malicious vehicles can be participated to disturb the network and attack. To prevent VANET from malicious activities, each vehicle should be able to determine the trustworthiness of the message to react on the information received from others by combining two approaches, probabilistic and deterministic approaches to have a perfect result. The probabilistic approach estimates the level of trust peer vehicles based on received information to decide whether forward the message or drop it. The deterministic approach measures the level of trust the received message based on calculating the distances by using received signal strength (RSS) and vehicles geolocation.

VEHICULA AD-HOC NETWORKCHAPTER-1: INTRODUCTIONThis paper focuses on investigating various aspects that are associated with the vehicular ad-hocnetwork for understanding the system to implement among general public. There is a briefdescription of the structure or framework of VANET followed by the possible security attacks andsome challenges to regularize this technology among public transportation system. At the lastsection, there is a brief discussion of future aspects of VANETs in the field of research. BACKGROUNDOFTHESTUDYThe Ad hoc network is considered as the distributed, temporary network system. For theformation of ad hoc network there is a dynamic link consists of nodes is very much required. Onthe same time, it does not rely upon the infrastructures with existing network, like gateway,router, or regular power supply etc. There is the Ad hoc network which is the kind of peer to peernetworks and also there is other node which has functions for data collecting, storing, as well asprocessing followed by forwarding. This solution is cost-effective in case of short-rangecommunication for some scenarios, like automation, environment sensing, or hazardspreventive. To improve these cases Vehicle Ad Hoc network has been introduced in recent years[ CITATION Qiu17 \l 16393 ].There are more than 1 billion of active Android users as of June, 2014 and it is growing innumbers day by day very rapidly. There are more than one million devices is being activated ineach day. For this dramatic growth in numbers, there are portable wireless devices which have ahuge market development in case of smart applications and these changes will interact with thelifestyles of users and also provides the context-aware interactions. It has been observed that the4

VEHICULA AD-HOC NETWORKmobile games markets have been grown and it has crossed the target range $23 billion in 2016[ CITATION Ahm171 \l 16393 ].It is also observed that from the last five years, there are automakers who have adopted theintegration platforms with onboard devices as well as personal smartphone. Therefore, theconnection between consumer electronic devices, like smart phones as well as the onboardvehicles has been reduced. Moreover, for multiple applications, the data makers are going forVANET applications to target the consumer electronics.The aim of VANET is to insure safe drive through improvement of the traffic flow as well as it isexpected for decreasing the car accidents with a great number. It has been also observed thatthe users of VANET would get benefitted from active road safety, infotainment along with trafficefficiency as well as management, especially in case of speed management and also co-operativenavigation [ CITATION Has17 \l 16393 ].As per the infrastructure concerned, VANET consists of two types of necessary units for thecommunication, management as well as registrations. Those are Roadside units (RSUs) or On-Board units (OBUs). In case of roadside units there are entities, like traffic lights. In case of On-Board units, the infrastructure management centers are belonging to it, like traffic managementcenters (TMCs) as well as the vehicle management centers [ CITATION Lia15 \l 16393 ]. 5

In case ofCAR-2-X communication system, it has been pursued that for CAR-2-CAR communicationconsortium (C2C-CC) there is the major driving force in case of vehicular communication withinEurope and that has been published in “manifesto”, 2007. This architecture system consists ofthree domains, like, ad hoc, in vehicle as well as infrastructure domain.Figure: components of VANETSource [ CITATION Mej14 \l 16393 ]6
