Solution Overview

Problem

Current vehicular communication systems lack efficient mechanisms for location-based access control and secure data sharing in Intelligent Vehicular Ad Hoc Networks, which is crucial for ensuring safe and efficient vehicle interactions and behavior consensus in dynamic environments.

Innovation Solution

A distributed ledger system with location-based permission access, utilizing smart contracts and blockchain technology, where vehicles and roadside units share and verify rules and behaviors, ensuring secure and transparent data access and consensus on vehicle actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a distributed ledger system with location-based permission is implemented, then data security and access control are improved, but system complexity increases

Engineering Contradiction:

Improvedata securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a distributed ledger system as an intermediary layer between vehicles and roadside units. This mediator manages location-based permissions and data access control, reducing the complexity burden on individual vehicles while enhancing overall system security through decentralized verification and immutable record-keeping.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If location-based access control is implemented in vehicular networks, then data sharing security is improved, but communication overhead increases

Engineering Contradiction:

Improvedata sharing securityVSAvoidcommunication overhead

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary location verification and permission checks before data sharing operations. By pre-establishing location-based access rules in the distributed ledger, the system avoids repeated authentication overhead during actual data exchanges, reducing communication energy consumption while maintaining security.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If blockchain technology is used for behavior consensus, then trust and verification are improved, but processing time increases

Engineering Contradiction:

Improvetrust and verificationVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the consensus process into location verification and behavior verification stages. The distributed ledger efficiently handles location-based permission validation, while behavioral consensus follows a streamlined process for pre-authorized vehicles. This segmentation reduces overall processing time while maintaining comprehensive trust verification.

Inventive Principle:

Principle #1Segmentation
