Wireless Sensor Performance Indication for Reliable Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems lack a method to effectively indicate the performance of sensors, leading to unreliable data transmission and decision-making due to unknown sensor limitations, such as accuracy and range, when sharing sensor data between devices.
Innovation Solution
A method where a wireless device identifies and transmits performance metrics, like range, resolution, and sensitivity, of its sensors along with sensor data, allowing receiving devices to assess data reliability and make informed decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is transmitted without performance information, then data transmission is simple and fast, but data reliability cannot be assessed leading to unreliable decision-making
Solution Approach 1:
The patent applies preliminary action by including sensor performance information (accuracy, range, resolution, sensitivity) in the data transmission packet before the receiving device processes the sensor data. This allows the receiving device to assess data reliability in advance, making informed decisions about whether to use the data for further processing or decision-making, thus resolving the contradiction between maintaining simple transmission and ensuring data reliability assessment capability
Solution Approach 2:
The patent introduces sensor performance information as an intermediary element that mediates between the sensor data and the receiving device's decision-making process. This intermediary provides the necessary context (performance metrics) that enables the receiving device to evaluate data reliability without complicating the core data transmission mechanism, effectively bridging the gap between simple transmission and reliable assessment
2Measurement precision
If multiple sensor performance metrics are included in transmission, then data assessment accuracy is improved, but transmission overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the essential sensor performance metrics (accuracy, range, resolution, sensitivity) that are most critical for data assessment, rather than transmitting all possible sensor characteristics. This selective extraction maintains measurement precision for the most important parameters while minimizing the quantity of transmitted data, resolving the contradiction between comprehensive assessment and transmission efficiency
Solution Approach 2:
The patent applies local quality by including performance information specifically for the sensor that captured the data, rather than general system-wide performance data. This targeted approach provides precise assessment information where needed (at the local sensor level) without unnecessarily increasing overall transmission volume, enabling accurate data evaluation with minimal overhead

AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) that transmits sensor data to another UE may also send information about the associated sensor and its performance. For example, the UE may determine a set of rules that apply to a sensor. The set of rules may define an association between a group of performance values and a group of performance levels corresponding to one or more metrics of the sensor. The UE may identify a performance value from the group of performance values for the sensor based on a performance level of the sensor and the set of rules. After determining the performance value, the UE may transmit an indication of the set of in a first data frame of a message and an indication of the performance value in a second data frame of the message.
