Solution Overview
Problem
Existing wireless networks face challenges in efficiently routing packets, especially for critical data and control signals, due to difficulties in identifying robust and redundant paths in wireless environments.

Engineering Contradiction Analysis
1Use of energy by moving object
If traditional routing protocols are used to optimize energy consumption, then energy efficiency is improved, but reliability and fault tolerance for critical data are worsened
Solution Approach 1:
The patent segments the routing problem by separating critical data packets into multiple independent paths. Each path is routed through different intermediate nodes, creating spatial separation that reduces correlation in disturbances. This segmentation allows the system to maintain energy efficiency while improving reliability through path diversity.
Solution Approach 2:
The patent changes the routing parameters by selecting paths based on disturbance correlation rather than just energy consumption. The system evaluates disturbance characteristics of wireless paths and chooses paths with low mutual correlation, transforming the routing optimization from a single-parameter (energy) to a multi-parameter (energy + reliability) approach.
2Reliability
If redundant paths are added to avoid single points of failure, then reliability is improved, but device complexity is worsened
Solution Approach 1:
The patent implements feedback mechanisms where intermediate nodes report disturbance information back to the control system node. This feedback enables the control system to dynamically determine mutual correlation between paths and adjust routing decisions, creating a closed-loop system that maintains reliability without excessive complexity.
Solution Approach 2:
The system performs preliminary actions by pre-evaluating disturbance characteristics of potential paths before routing critical data. The control system determines mutual correlation between paths in advance and selects optimal paths beforehand, avoiding the need for complex real-time adjustments during data transmission.
3Productivity
If packets are transmitted in parallel on multiple paths, then productivity is improved, but loss of information is worsened due to correlated disturbances
Solution Approach 1:
The patent extracts the correlation information from the routing decision process. By obtaining and analyzing disturbance information from intermediate nodes, the system separates the routing selection from the data transmission, allowing parallel transmission while filtering out correlated disturbance effects through intelligent path selection.
Solution Approach 2:
The patent adds a new dimension to path selection by considering the correlation characteristics of disturbances rather than just traditional routing metrics. This dimensional addition allows the system to achieve both parallel transmission efficiency and reduced packet loss by selecting paths with low mutual correlation in the disturbance space.
