Solution Overview
Problem
Existing routing selection methods in wireless communication are limited by specific function nodes or topology structures, which restrict the flexibility and efficiency of data transmission in asymmetric links.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If routing is selected depending on a specific functional node or topology structure, then the routing selection process is simplified, but the flexibility and adaptability of the system is reduced
Solution Approach 1:
The patent applies universality by enabling arbitrary intermediate nodes (not just specific functional nodes) to perform routing request reception, link quality acquisition, and routing determination. This multi-functional approach allows any node in the network to participate in routing decisions, eliminating the need for specialized routing nodes and thereby increasing system flexibility while maintaining manageable complexity through standardized node behaviors.
2Ease of manufacture
If existing routing methods are used in asymmetric links, then the implementation is straightforward, but the data transmission efficiency is limited
Solution Approach 1:
The patent implements feedback mechanisms where intermediate nodes continuously acquire link quality information and use this feedback to dynamically update and optimize routing paths. Nodes receive routing requests, measure link qualities, calculate optimal paths based on accumulated feedback from multiple measurements, and adjust routing decisions accordingly, thereby significantly improving data transmission efficiency in asymmetric links while maintaining practical implementability.
3Productivity
If arbitrary intermediate nodes perform routing determination based on link quality, then the adaptability and efficiency are improved, but the node operation complexity increases
Solution Approach 1:
The patent applies parameter changes by having intermediate nodes dynamically adjust routing decisions based on acquired link quality parameters. Nodes measure and compare link quality values, and use these parameter changes to optimize path selection. This data-driven approach improves transmission efficiency while keeping node operation complexity manageable through standardized parameter measurement and comparison procedures.
4Reliability
If routing selection is based on comprehensive link quality assessment, then the path optimization is improved, but the information processing requirement increases
Solution Approach 1:
The patent implements partial action by having intermediate nodes acquire and process only the necessary link quality information needed for routing decisions, rather than processing all possible network parameters. Nodes selectively measure relevant link qualities along potential paths and use this partial but sufficient information to make optimized routing decisions, thereby achieving reliable path optimization without excessive information processing overhead.

AI summary
A method, apparatus and/or system of selecting a routing in an asymmetric link, in which an arbitrary intermediate node of the at least one intermediate node receives routing request information including a first link quality for a path from the source node to the arbitrary neighbor node from an arbitrary neighbor node of the arbitrary intermediate node, acquires a second link quality for a path between the arbitrary intermediate node and the arbitrary neighbor node, acquires a third link quality based on the first and second link qualities, updates the first link quality in the routing request information with the third link quality, and broadcasts an updated routing request information to other neighbor node for the destination node to determine at least one of a desirable forward path or a desirable backward path from the source node to the destination node, may be provided.
