A Trust Management-Based Route Planning Scheme in LBS Network

Location-based Service (LBS) has attracted growing attention in the field of Internet of Vehicles (IoV), and a route planning scheme is a research hotspot. Research shows that one serious problem in the field of intelligent transportation is the waste of computing resources. In addition, the process blockage caused by malicious requests from vehicles is another overlooked issue needs to be considered. In this paper, a dual-tiered path index based parallel route planning model is proposed to accelerate the process of route planning. Then, based on the decentralization and security of the blockchain, we propose a trust management for identifying malicious vehicles, and the sensitive information is stored in the blockchain. Extensive experiment results show that our proposal is feasible and effective.
