Abstract

Vehicular Ad Hoc Networks is also known as intelligent transportation systems. The aim
is to provide intervehicle communication and roadside to vehicle communication to
increase road safety, improve the efficiency of local traffic flow by providing accurate
and timely information to driver as well as to realize the concept of autonomous vehicles
in future. In VANET, the data transmission is done in an open access medium, which
exposes the network to various security attacks. Moreover, due to high mobility,
establishing network security becomes more challenging as the movement of nodes
constantly changes network topology. This leads to potential security threats such as
Denial of Services (DoS) attacks, pollution attack, impersonation, and fabrication
attacks of data in the network.In this paper, a possible solution is proposed to overcome
these attacks. The proposed solution adapts the RSSI-localization into the VANET
system that depends on public key infrastructure (PKI). Localization based on RSSI will
be used as a method to secure the data communication and prevent the attack on
autonomous vehicle through WSN. Each signal will be authenticated by RSSI in order to
detect any attacks. The chance of the security attack on autonomous vehicle can be
minimize by using localization based RSSI. Whereas, with the PKI, security of the
message is increased significantly. With this proposed solution, it is expected that the
attacks will have less impact on the VANET.
