1Reliability
If multiple backhaul paths are formed in a wireless network, then network connectivity and redundancy are improved, but transmission efficiency and data transmission rate deteriorate due to varying bandwidths, communication qualities, frequency channels, and topological types
Solution Approach 1:
The patent transforms multiple backhaul paths with different physical parameters (bandwidth, communication quality, frequency channels, topological types) into a unified evaluation framework by converting them into comparable path quality parameters. This allows the system to objectively compare and select optimal paths despite the underlying diversity of network conditions.
Solution Approach 2:
The patent replaces complex manual evaluation of multiple path parameters with an automated path quality calculation mechanism. The controller node automatically computes path quality parameters based on predefined formulas and selects optimal paths without human intervention, substituting mechanical evaluation processes with computational algorithms.
2Productivity
If path selection is based on multiple parameters (bandwidth, communication quality, frequency channels, topological types), then transmission efficiency is improved, but device complexity and control complexity increase
Solution Approach 1:
The patent segments the complex path selection process into distinct functional modules: parameter collection, path quality calculation, and path selection. The controller node divides the evaluation of multiple parameters (bandwidth, communication quality, frequency channels, topological types) into separate calculation steps, making the overall system more manageable and easier to implement.
Solution Approach 2:
The patent introduces path quality parameters as intermediary values that mediate between the complex input parameters and the final path selection decision. These intermediate calculations simplify the relationship between multiple influencing factors and the selection outcome, reducing direct control complexity.
3Measurement precision
If comprehensive path quality parameters are calculated for all candidate paths, then optimal path selection is improved, but computation time and processing resources increase
Solution Approach 1:
The patent applies partial action by calculating path quality parameters only for necessary evaluation criteria rather than exhaustively analyzing all possible path characteristics. The system computes sufficient statistics (path quality parameters) to make optimal selections without performing complete exhaustive searches, balancing accuracy with computational efficiency.
