Vehicle-to-X Message Discarding Based on Available Computing Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-X communication systems do not adequately account for available computing power when determining which messages to discard, leading to the need for reserved computing resources.
Innovation Solution
A preprocessing technique that dynamically adjusts the number of vehicle-to-X messages to be discarded based on the number of received messages and available computing power, using adapted classification parameters such as threshold values and relevance criteria to optimize processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If preprocessing techniques are used to discard irrelevant vehicle-to-X messages early in the processing chain, then computing power is saved, but the number of messages that can be processed is reduced
Solution Approach 1:
The patent implements dynamic adjustment of the number of messages to be discarded based on the currently available computing power. The system determines the available computing power in each operating cycle and adapts the discarding strategy accordingly, allowing the processing capacity to fluctuate within available resources rather than being fixed conservatively.
Solution Approach 2:
The system changes the parameter of message discarding quantity based on the determined available computing power. By adjusting this parameter dynamically, the system optimizes the balance between saving computing power and processing sufficient messages to maintain system functionality.
2Loss of information
If more vehicle-to-X messages are processed, then information completeness is improved, but computing power requirements increase
Solution Approach 1:
The system employs feedback by continuously determining the available computing power and using this information to adjust the number of messages to be discarded. This closed-loop approach ensures that information processing remains aligned with actual system capabilities, preventing information loss while avoiding unnecessary computing power consumption.
Solution Approach 2:
The system performs partial processing by discarding some messages when computing power is limited, rather than attempting to process all received messages. The degree of partial action is dynamically adjusted to match available resources, ensuring sufficient information processing without exceeding power constraints.
3Reliability
If computing power is reserved to handle peak message loads, then system reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The system replaces static reserved computing power with dynamic determination of available computing power in each operating cycle. This allows the system to adapt to varying message loads and actual resource availability, maintaining reliability when needed while improving resource utilization efficiency by avoiding permanent reservations of unused resources.
Solution Approach 2:
The system determines its own available computing power and autonomously adjusts the message discarding strategy without external intervention or pre-configured reserves. This self-service approach optimizes resource allocation in real-time, improving both reliability and efficiency.
