Cooperation and radio silence strategy in Mix Zone to Protect Location Privacy of Vehicle in VANET

Abstract

With increase in the population, the number of registered vehicles hasdramatically increased over all the world, and this leads to a high rate of trafficaccidents on the roads. Therefore, in order to prevent such accidents, anIntelligent Transportation Systems (ITSs) is needed to be installed to notifydrivers of obstacles in advance. Recently, the Internet of things (IoT) evolvesthe vehicular communications and covers this technology under the Internet ofvehicles (IoV) application. IoV is a new field for the automotive industry and asignificant part of the smart cities. However, protecting the privacy of vehicle'slocation is the most challenging subject in the vehicular communication, asbecause it threatens the personal life of drivers. This paper provides cooperationand radio silence strategy in mix zone (CRSMZ) to protect location privacy ofvehicle in IoV. The strategy implements either cooperation or radio silencedepending on the speed of the vehicle while it is in mix _zone. The simulationresults show that CRSMZ is an efficient strategy to protect location informationof vehicle drivers. CRSMZ outperforms the existing strategies in terms of meanof the number tracker confusion, continuous tracking period and max of theentropy.
