Consensus Problem in V2V-based Vehicular Ad Hoc Networks

Chien-Fu Cheng

Abstract— Intelligent vehicles use Vehicular Ad Hoc Networks (VANETs) to communicate with other intelligent vehicles. However, messages are transmitted wirelessly in VANET and therefore vulnerable to malicious attacks. In the event of a malicious attack, the On-Board Unit (OBU) in intelligent vehicles will not function properly, and accidents are likely to occur. Therefore, building a highly reliable and fault-tolerant VANET is of high important. In this paper, based on the characteristics of Vehicle-to-Vehicle (V2V) based VANETs, we design a fault-tolerant consensus protocol to improve fault tolerance of V2V-based VANETs.

Index Terms— vehicular ad hoc networks, vehicle-to-vehicle, fault-tolerant, consensus problem.
