Abstract
With many advances in sensor technology and the Internet of Things, Vehicle Ad Hoc Network (VANET) is becoming a new generation. VANET’s current technical challenges are deploying decentralized architecture and protecting privacy. Because Blockchain features are decentralized, distributed, mass storage, and non-manipulation features, this paper designs a new decentralized architecture using Blockchain technology called Blockchain-based VANET. Blockchain-based VANET can effectively resolve centralized problems and mutual distrust between VANET units. To achieve this, it is needed to provide scalability on the blockchain to run for VANET. In this system, our focus is on the reliability of incoming messages on the network. Vehicles check the validity of the received messages using the proposed Bayesian formula for trust management system and some information saved in the Blockchain. Then, based on the validation result, the vehicle computes a rate for each message type and message source vehicle. Vehicles upload the computed rates to Roadside Units (RSUs) in order to calculate the net reliability value. Finally, RSUs using a sharding consensus mechanism generate blocks, including the net reliability value as a transaction. In this system, all RSUs collaboratively maintain the latest updated Blockchain. Our experimental results show that the proposed system is effective, scalable and dependable in data gathering, computing, organization, and retrieval of trust values in VANET.
Highlights
Vehicular ad hoc network (VANET) is one of the most significant current discussion in the intelligent transport [1]
It is described how to simulate the proposed system in details. It is simulated the system with 20 Roadside Units (RSUs), 10–3000 vehicles, and 3 events: accident, traffic, and road destruction
Each RSU in the system receives transactions that are corresponding to the committee that it belongs to
Summary
Vehicular ad hoc network (VANET) is one of the most significant current discussion in the intelligent transport [1]. VANET provides a platform for vehicles to share road-related messages with other peers. This ability has greatly improved the management of urban traffic and road accidents. The primary option, for the defined purpose, is a centralized system In this kind of trust management system, all messages are stored and processed in a central server. Centralized systems can carry risks such as bottlenecks caused by increased layers of approvals and slower decision-making and single-point of failure. This challenge faces the system with efficiency and communication between node’s problems. Regarding the decentralized approach, it is a practicable tool for VANET
