Abstract

With increase in the population, the number of registered vehicles has dramatically increased over all the world, and this leads to a high rate of traffic accidents on the roads. Therefore, in order to prevent such accidents, an Intelligent Transportation Systems (ITSs) is needed to be installed to notify drivers of obstacles in advance. Recently, the Internet of things (IoT) evolves the vehicular communications and covers this technology under the Internet of vehicles (IoV) application. IoV is a new field for the automotive industry and a significant part of the smart cities. However, protecting the privacy of vehicle's location is the most challenging subject in the vehicular communication, as because it threatens the personal life of drivers. This paper provides cooperation and radio silence strategy in mix zone (CRSMZ) to protect location privacy of vehicle in IoV. The strategy implements either cooperation or radio silence depending on the speed of the vehicle while it is in mix _zone. The simulation results show that CRSMZ is an efficient strategy to protect location information of vehicle drivers. CRSMZ outperforms the existing strategies in terms of mean of the number tracker confusion, continuous tracking period and max of the entropy.

Highlights

To ensure traffic safety and mitigate accidents, attention has been paid to vehicle networks, which are one of the most important technologies intelligent transportation system [1]
The work in this paper propose a new strategy based on choosing a method for changing the pseudonyms according to vehicle velocity and comparing the results with two existing strategies Slow and CPN
If its speed is within the low speed limits, it enters the radio silence, after that it performs the process of changing the pseudonym

Summary

Introduction

To ensure traffic safety and mitigate accidents, attention has been paid to vehicle networks, which are one of the most important technologies intelligent transportation system [1]. To secure communication between the vehicles, the vehicles must be equipped with a device called onboard unit (OBU) [4], [5] These messages are sent wirelessly, so the driver can be tracked by the attacker. The greater the waiting time, the greater the number of vehicles arriving at the intersection, and the greater the entropy This strategy needs to be controlled by the RSUs that select the vehicles for the swap operation. In [8], the authors proposed at the Velocity Based Pseudonym Changing Strategy, so that a vehicle moves at different velocities, and this depends on the driver’s behavior, the nature of the road and the driving time. The main objectives of this study are: to increase the level of privacy required and reduce the percentage of continuous tracking time
