Access Point Channel Selection via Neighboring Reaction Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managed wireless access points experience oscillating behavior and reduced performance improvement due to reactive configuration changes from neighboring unmanaged access points, leading to service interruptions and lower Quality of Service (QoS).
Innovation Solution
A device that learns the reaction probabilities of neighboring access points by repeatedly switching channels and measuring responses, calculating gain and probability for each channel combination to select the optimal configuration, anticipating and minimizing oscillating behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the managed access point changes configuration to improve performance, then throughput and coverage are improved, but the unmanaged access point reacts by changing its configuration which reduces the performance improvement and causes oscillating behavior
Solution Approach 1:
The system performs preliminary actions by proactively selecting optimal channels for unmanaged access points based on predicted behavior patterns, rather than reactively responding to their changes. This preliminary configuration reduces oscillations by anticipating and preventing reactive behavior before it occurs.
Solution Approach 2:
The system implements feedback mechanisms by monitoring channel changes and performance metrics, then adjusting channel assignments to account for the reactive behavior of unmanaged access points. This closed-loop feedback stabilizes the network by continuously adapting to observed patterns.
2Reliability
If channel measurements are performed to determine optimal configuration, then interference from unmanaged access points is accounted for, but oscillating behavior occurs leading to service interruptions and lower Quality of Service
Solution Approach 1:
The system performs preliminary channel assignments based on predicted behavior patterns before oscillations occur. By pre-configuring channels that account for unmanaged access point reactions, the system avoids repeated reconfigurations and service interruptions, thereby reducing reconfiguration time while maintaining QoS.
Solution Approach 2:
The system dynamically adapts to the reactive behavior of unmanaged access points by adjusting channel assignments based on observed patterns. This dynamic approach allows the system to maintain stability and QoS by flexibly responding to changing conditions without excessive reconfiguration.
3Productivity
If the managed access point continuously changes configuration to optimize performance, then performance improvement is pursued, but oscillating behavior with unmanaged access points leads to service interruptions
Solution Approach 1:
The system performs preliminary channel selections that account for the reactive behavior of unmanaged access points. By anticipating oscillations and pre-selecting stable channel combinations, the system achieves performance optimization without causing service interruptions, thereby maintaining both productivity and reliability.
Solution Approach 2:
The system applies preliminary anti-action by counteracting the expected reactive behavior of unmanaged access points before oscillations occur. By pre-adjusting channel assignments to compensate for anticipated reactions, the system prevents performance degradation and service interruptions while maintaining optimal throughput.
