Receiver-Aware Sensor Information Sharing via Unicast and Groupcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ITS services do not consider the state of the receiver, leading to increased network traffic, battery consumption, and inefficient information sharing, particularly in V2X communication, as they transmit sensor information without considering the specific needs or capabilities of individual receivers.
Innovation Solution
A method for processing and transmitting valid information to specific receivers or groups based on their state information or requests, using unicast, groupcast, or multicast communication, allowing sensor information providers to selectively provide relevant data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor information is transmitted to all receivers without considering their state, then information coverage is improved, but network traffic and battery consumption increase
Solution Approach 1:
The patent applies local quality by customizing information transmission according to the specific state and capabilities of each receiver. The transmitter adjusts the information content, format, and transmission parameters based on receiver-specific characteristics such as computing capability, current state, and information needs, rather than using a uniform transmission approach for all receivers.
Solution Approach 2:
The patent implements dynamics by making the information transmission adaptive and changeable based on receiver state. The system continuously monitors receiver states and dynamically adjusts transmission parameters including information selection, compression level, and transmission timing to match current receiver conditions and capabilities.
2Loss of information
If comprehensive sensor information is transmitted to all receivers, then information completeness is improved, but network traffic increases
Solution Approach 1:
The patent applies the extraction principle by selectively removing unnecessary information from the complete sensor data set based on receiver-specific needs and capabilities. The system extracts only the relevant subset of information required by each receiver, excluding redundant or irrelevant data to reduce transmission volume while maintaining information completeness for the specific use case.
Solution Approach 2:
The patent implements partial action by transmitting a customized portion of the complete sensor information rather than all available data. The system determines the optimal subset of information to transmit based on receiver state, prioritizing critical information while omitting less important data, thereby achieving sufficient information completeness with reduced network traffic.
3Measurement precision
If detailed sensor information is transmitted, then information accuracy is improved, but processing load on receivers increases
Solution Approach 1:
The patent applies local quality by customizing the level of information detail and accuracy according to each receiver's processing capabilities and specific needs. The transmitter adjusts information granularity, resolution, and complexity based on receiver characteristics, providing high-precision information to capable receivers while delivering simplified versions to devices with limited processing power.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting information transmission parameters such as data resolution, compression level, and detail granularity based on receiver state. The system modifies these parameters in real-time to balance information accuracy with processing load, ensuring that receivers can process the transmitted information effectively regardless of their computational capabilities.
4Ease of operation
If information is transmitted without considering receiver state, then transmission simplicity is improved, but information sharing efficiency decreases
Solution Approach 1:
The patent applies feedback by implementing a state information exchange mechanism where receivers provide their current state and capability information to the transmitter. This feedback loop enables the transmitter to adapt its information transmission strategy to match receiver needs and capabilities, significantly improving information sharing efficiency while maintaining operational simplicity through automated state-based decision making.
Solution Approach 2:
The patent implements dynamics by making the information transmission process adaptive based on receiver state feedback. The system dynamically adjusts transmission parameters, information selection, and formatting in response to changing receiver conditions, thereby optimizing information sharing efficiency without requiring complex manual configuration or intervention.
