Privacy aware routing in vehicular ad-hoc networks

Abstract

The fundamental objective of vehicular communication systems VANETs, is the enhancement of traffic safety and security where vehicles can exchange data in a safe manner, as well as convenience to both drivers and passengers.Privacy of individual vehicles and drivers which is a key factor, became a target to attackers who can obtain this information from the frequent broadcasting of real-time positioning information and the exchange of data in the network. For that a large body of work has emerged during recent years, proposing the use of pseudonyms to identify vehicles, ensuring that pseudonymity can satisfy both security and privacy requirements. In this thesis, we will learn more about the vehicular networks. Then we will see the various security challenges and some of the major attacks that may be faced. As well as the proposed solutions that can be implemented against them. Finally we will give our proposed solution, Which is the creation of a position-based routing protocol using the greedy forwarding strategy, in order to solve the problem encountered in the other protocols which use the pseudonym change strategy. The performance will be evaluated according to the simulation results which show the efficiency of our solution.
