Vehicular Micro Cloud Strategy System for Overlapping Service Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In overlapping vehicular micro cloud areas, vehicles face challenges in maintaining uninterrupted vehicular cloud services due to members leaving or joining multiple micro clouds, leading to task assignment conflicts and incomplete tasks, particularly in areas like intersections, roundabouts, and toll gates where multiple micro clouds are active.
Innovation Solution
A strategy system that determines and executes strategies to ensure uninterrupted vehicular cloud services by retrieving intrinsic and extrinsic data to manage task assignments and prioritize tasks for ego vehicles acting as hub vehicles or members within overlapping micro cloud areas, using proactive or reactive approaches to maintain continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If members join multiple vehicular micro clouds in overlapping areas, then the availability of computing resources increases, but task completion reliability deteriorates due to conflicting task assignments
Solution Approach 1:
The patent introduces a strategy system as an intermediary that manages task assignments when vehicles are members of multiple vehicular micro clouds. The strategy system receives task assignments from multiple hub vehicles, evaluates them based on criteria such as task urgency, vehicle capabilities, and current workload, and selects the most appropriate task to execute. This mediator resolves conflicts between multiple task assignments and ensures reliable task completion while maintaining the benefit of multiple cloud memberships.
2Device complexity
If members leave vehicular micro clouds in overlapping areas, then the complexity of task management decreases, but service continuity deteriorates
Solution Approach 1:
The strategy system performs preliminary actions by proactively managing task assignments before members leave the vehicular micro cloud. When a vehicle indicates it will leave a micro cloud, the strategy system anticipates the potential service interruption and pre-arranges task handovers or reassignments to other members. This ensures service continuity is maintained while avoiding the complexity of reactive real-time reassignments.
3Area of stationary object
If multiple vehicular micro clouds operate in the same area, then the coverage area increases, but task assignment conflicts increase
Solution Approach 1:
The strategy system implements feedback mechanisms where vehicles continuously report their task completion status, current workload, and availability to the strategy system. Hub vehicles also provide feedback about task requirements and priorities. This feedback loop enables the strategy system to dynamically adjust task assignments, resolve conflicts between multiple micro clouds, and optimize the distribution of tasks across the overlapping coverage areas without increasing complexity.
