Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of vehicular micro clouds is limited due to the lack of vehicles equipped with rich computational resources and V2V communication capabilities, which are necessary for providing vehicular micro cloud services.
Innovation Solution
A hub system is introduced that selects a hub vehicle with the necessary functionality to enable vehicular micro clouds to provide services, utilizing software installed in vehicles with V2X communication capability to offer communication, service, and security hub functionalities, allowing vehicles without V2V communication to join and offload resource-intensive tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles without V2V communication capabilities are excluded from vehicular micro clouds, then communication reliability is improved, but system adaptability deteriorates
Solution Approach 1:
The patent introduces a hub vehicle as an intermediary component that mediates communication between V2V-equipped vehicles and V2V-less vehicles. The hub vehicle receives messages from remote vehicles without direct V2V capability and relays them to the vehicular micro cloud, enabling indirect communication while maintaining communication reliability through the trusted hub intermediary.
2Productivity
If computational resources are distributed across all vehicles, then system productivity is improved, but device complexity increases
Solution Approach 1:
The patent segments the vehicular micro cloud into distinct functional roles: hub vehicles that manage coordination and resource allocation, and remote vehicles that contribute computational resources. This segmentation allows the system to aggregate productivity from multiple vehicles while the hub vehicle centralizes the complex management functions, preventing complexity from proliferating across all devices.
3Reliability
If threshold requirements for hub vehicle selection are increased, then service quality is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic hub vehicle selection based on predefined threshold criteria for computational resources, communication capabilities, and trustworthiness. The system autonomously evaluates candidate vehicles and designates hub vehicles without manual intervention, maintaining high service quality through strict thresholds while preserving ease of operation through automated decision-making.
