Engineering Contradiction Analysis
1Productivity
If traditional mesh topology is used with fixed active and backup links, then network结构简单 (structure is simple), but network throughput and connectivity are limited due to inability to reorganize communication paths
Solution Approach 1:
The patent implements dynamic topology optimization where the centralized system continuously monitors network state and reconfigures mesh links in real-time. Access points can switch between active and backup links based on current interference conditions, transforming the static mesh topology into a dynamic system that adapts to changing network conditions to maximize throughput.
Solution Approach 2:
The system employs feedback mechanisms where the centralized controller receives performance metrics from access points and uses this information to optimize topology configuration. The feedback loop enables continuous improvement of network performance by adjusting link assignments based on measured interference and throughput conditions.
2Adaptability or versatility
If centralized topology optimization is implemented with real-time monitoring and reconfiguration, then network throughput and adaptability improve, but system complexity and computational requirements increase
Solution Approach 1:
The patent introduces a centralized system as an intermediary between access points and the network core. This intermediary collects topology data from all APs, performs optimization calculations, and distributes reconfiguration commands. By centralizing the complex optimization logic, individual APs remain simple while the network as a whole gains advanced reorganization capabilities.
Solution Approach 2:
The system creates and evaluates multiple candidate topology configurations (copies of the current topology) to identify the optimal arrangement. By simulating different link assignments and predicting their performance, the system can select the best configuration without requiring complex real-time calculations during actual data transmission.
3Measurement precision
If node competition index (NCI) calculations are performed to quantify interference, then interference measurement precision improves, but computational overhead increases
Solution Approach 1:
The system calculates Node Competition Indices for only the most critical links or a subset of access points at any given time, rather than performing exhaustive calculations for all network links simultaneously. This partial action approach provides sufficient interference measurement precision for optimization decisions while significantly reducing computational overhead and optimization time.
Solution Approach 2:
The system pre-calculates interference metrics and Node Competition Indices during periods of low network activity or in advance of topology changes. By performing these computationally intensive measurements beforehand, the system minimizes the time required for actual topology optimization when network performance is most critical.
