Sybil attack in vanet operating in an urban environment: an overview

Abstract

Networking technology in the present scenario has the latest invention called ad hoc networks. VANET is a type of ad hoc network where vehicles communicate with each other in a network. From the last few decades, VANET is becoming popular where relocation, mobility, and converge of location by the vehicles were impossible to achieve by using a wired network. VANET provides the growth of intelligent transport systems by providing safety and comfort consideration for both drivers and passengers. VANET is an open-access network that may prone to various types of attacks. This paper is an overview of the study of various attacks in VANET focusing on Sybil attack in VANET which operates under the urban environment. A comparison of different methods of detection technique for Sybil attack is also included.
