Vehicle Mesh Network Routing Protocol Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh networks between vehicles face inefficiencies due to transient connections caused by changing vehicle speeds and directions, which hinder effective edge computing and data sharing, particularly for large files, as current routing protocols are not optimized for dynamic vehicle motion states.
Innovation Solution
A system and method that determine the motion states of vehicles within a mesh network and selectively choose between dynamic and static routing protocols based on these states, using an electronic control unit or computing device to establish optimal network interfaces and routing paths, thereby stabilizing connections when vehicles are stationary or moving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a static routing protocol is used when vehicles are moving, then network stability is improved, but adaptability to changing motion states deteriorates
Solution Approach 1:
The system dynamically switches between static and dynamic routing protocols based on vehicle motion states. When vehicles are stationary or moving at constant speeds, static routing is used for stability. When motion states change, the system transitions to dynamic routing to adapt to new conditions, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The routing protocol selection is changed based on motion state parameters. The system monitors vehicle motion parameters and adjusts the routing protocol parameter accordingly, selecting static routing for stable motion conditions and dynamic routing for changing conditions.
2Adaptability or versatility
If a dynamic routing protocol is used when vehicles are stationary, then adaptability to motion changes is improved, but network efficiency deteriorates
Solution Approach 1:
The system applies dynamic routing protocol only when vehicle motion states indicate potential changes, rather than continuously. This dynamic selection based on motion state detection ensures adaptability is available when needed while maintaining network efficiency during stable conditions.
Solution Approach 2:
The routing protocol parameter is changed based on motion state parameters. When motion state parameters indicate stability (stationary or constant velocity), static routing is selected for efficiency. When parameters indicate acceleration, deceleration, or direction changes, dynamic routing is selected for adaptability.
3Device complexity
If routing protocols are not optimized for motion states, then device complexity is reduced, but network reliability deteriorates
Solution Approach 1:
The routing protocol selection is segmented into different modes (static and dynamic) based on motion states. This segmentation allows the system to use simpler static routing when appropriate while switching to more complex dynamic routing only when reliability demands it, optimizing the balance between complexity and reliability.
Solution Approach 2:
Motion state detection acts as an intermediary between vehicle physical state and routing protocol selection. This intermediary layer enables automatic, intelligent selection of appropriate routing protocols based on motion conditions, improving reliability without requiring complex manual configuration or oversight.
