REPLACE: A Reliable Trust-based Platoon Service Recommendation Scheme in VANET

Abstract

The fast development of intelligent transportation paves the way for innovative techniques in highway, and an entirely new driving pattern of highway vehicular platooning might offer a solution to our long haunted problem of road congestion, travel comfort and road safety. In this vehicular platooning system, a platoon head vehicle provides platoon service to its user vehicles. However, some badly-behaved platoon head vehicles may put the platoon in danger, which makes it crucial for user vehicles to distinguish and avoid them. In this paper, we propose a reliable trust-based platoon service recommendation scheme, called REPLACE, to help the user vehicles avoid choosing badly-behaved platoon head vehicles. Specifically, at the core of REPLACE, a reputation system is designed for the platoon head vehicles by collecting and modeling their user vehicle’s feedbacks. Then an iterative filtering algorithm is designed to deal with the untruthful feedbacks from user vehicles. A detailed security analysis is given to show that our proposed REPLACE scheme is secure and robust against badmouth, ballot-stuffing, newcomer and on-off attacks existing in VANETs. In addition, we conduct extensive experiments to demonstrate the correctness, accuracy and robustness of our proposed scheme.
