Review on security attacks and mechanism in VANET and MANET

Abstract

Ad hoc wireless communication is an infrastructure-less network and adaptable to all environments. It is characterized by self-organizing, dynamic topology, and self-healing. These characteristics are most common for both MANET and VANET. In these networks, security is a major concern for data transmission. Ad hoc security is violated by various security attacks. In this paper, we are analyzing the common security attacks and their exploitation in various layers. The various security mechanisms and protocols are discussed in both VANET and MANET for secure data transmission.
