A dummy location generation model for location privacy in vehicular ad hoc networks

Abstract

The vehicular ad hoc networks are designed to tackle the problems that occur due to the proliferation of vehicles in our society. However, most of its applications require the access to location of vehicles participating in the network and may lead to life-threatening situations. Hence, a careful solution is required while sharing the credentials including location. In this work, we propose to use the dummy location generation of the vehicles. This method helps in protecting the location privacy of a vehicle by creating confusion in the network. This paper contributes to a dummy location generation method, by evaluating the conditional probabilities of location and time pairing. Firstly, we describe the technique used by the adversary and present our dummy location generation method which is simple in nature and gives efficiency as compared to existing methods. Results prove the validity of our proposed model.
