Vehicle Coordination Using Verified Sensor Data Consensus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack an efficient method to coordinate operations among vehicles in a traffic system, particularly in scenarios where sensor data from multiple vehicles needs to be integrated and verified for cooperative decision-making.
Innovation Solution
A method utilizing a distributed ledger, such as a blockchain, to verify and integrate sensor data from certified vehicles, allowing for consensus-based operations, including the creation of digital signatures and the addition of new blocks based on sensor outputs from radio transmissions, enabling vehicles to coordinate their actions in a traffic system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data from multiple vehicles is integrated and verified using a distributed ledger, then coordination and safety in traffic systems is improved, but system complexity and computational overhead increases
Solution Approach 1:
The system segments the traffic coordination problem into individual vehicle sensor data units, each verified and recorded as a separate block in the distributed ledger. This allows incremental verification and coordination without requiring all vehicles to simultaneously process all data, reducing computational overhead while maintaining reliability.
Solution Approach 2:
The distributed ledger acts as an intermediary between vehicles, providing a trusted platform for data verification and consensus without requiring direct complex communication between all vehicle pairs. This mediator approach simplifies the overall system architecture while ensuring reliable coordination.
2Reliability
If digital signatures and blockchain verification are implemented for each radio transmission, then data trustworthiness is improved, but processing time and energy consumption increases
Solution Approach 1:
Vehicles perform preliminary actions by pre-generating and attaching digital signatures to sensor data before transmission. The distributed ledger system pre- validates the signature mechanisms and maintains a ready state for verification. This preliminary preparation reduces the actual verification time during critical traffic coordination moments.
3Adaptability or versatility
If consensus-based operations are implemented among certified vehicles, then cooperative decision-making is improved, but communication overhead and network traffic increases
Solution Approach 1:
The system extracts only the essential sensor data and verification information needed for consensus, removing redundant communication overhead. Each vehicle transmits and verifies only the critical data elements required for cooperative decision-making, rather than exchanging complete data sets, thus reducing network traffic while maintaining adaptability.
