Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication-sensing integrated systems, selecting an unsuitable node for sensing can lead to low sensing efficiency and unsatisfactory results due to variations in sensing capabilities, location, and resource availability among nodes.
Innovation Solution
A wireless communication method where a first node sends first sensing assistance information to a sensing control node, which includes information such as sensing capability, operating bandwidth, precision, and resource occupancy of the first sensing node, enabling the control node to select the most suitable nodes for sensing tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple nodes with sensing capabilities are deployed around a sensed target, then the coverage and availability of sensing nodes are improved, but the sensing efficiency and quality deteriorate due to unsuitable nodes participating in sensing
Solution Approach 1:
The patent applies preliminary action by having sensing nodes send sensing assistance information (including capability, location, and resource occupancy details) to the sensing control node before actual sensing tasks are assigned. This allows the control node to pre-evaluate and select only suitable nodes for sensing tasks, preventing unsuitable nodes from participating and thereby maintaining high sensing efficiency despite having multiple nodes available.
2Adaptability or versatility
If nodes with different sensing capabilities are allowed to participate in sensing, then the system flexibility and adaptability are improved, but the sensing precision and quality deteriorate due to unsuitable nodes
Solution Approach 1:
The patent applies local quality by evaluating and selecting sensing nodes based on their specific local characteristics and capabilities. The sensing control node receives and processes sensing assistance information that includes node-specific details (capability, location, resource occupancy) to determine which nodes are suitable for particular sensing tasks. This ensures that only nodes with appropriate local qualities are selected, maintaining sensing precision while still allowing flexible node selection across the network.
3Reliability
If sensing assistance information is collected from multiple nodes, then the node selection accuracy is improved, but the information processing complexity and system overhead increase
Solution Approach 1:
The patent applies the extraction principle by having sensing nodes send only the necessary sensing assistance information (capability, location, resource occupancy) to the sensing control node. The control node extracts and processes only the relevant information needed for node selection, rather than handling all possible node data. This selective information extraction maintains high selection accuracy while reducing the processing complexity and system overhead.
