Vehicular Ad-Hoc network or VANET is a
subgroup of mobile Ad-Hoc network or MANET. VANET
does not have fixed topology and the nodes move one location
to another location. It is used for life saving of passengers. To
transfer a packet from client to server it should follow a
routing protocol. Many challenges and security attack are in
VANET like DOS attack, DDOS attack, Sybil attack,
Grayhole attack. So in this paper we discuss about different
types of attack in VANET.
Manpreet kaur : is currently in the final year of degree course of
Master’s of engineering and technology from Sri Sai College of
Engineering and Technology, Manawala, , Amritsar under I.K.
Gujral Punjab Technical University, Jalandhar.
Nitin Bhagat : the guide and assistant professor in Sri Sai
College of Engineering and Technology, Manawala Amritsar under
I.K. Gujral Punjab Technical University, Jalandhar.
This paper concludes that many researchers provide their
methodologies to solve this savior attack but still this is
one of the major prone in VANETs, because this attack
may also be the reason of other attacks like denial of
service attack, distributed denial of service, Sybil attack,
grey hole attack, black hole attack a name of few. We
know that wireless medium is used in VANET for
transmission of data or information from vehicle to vehicle
so there are chances of various attacks in VANET .
