Adaptive Throughput Capping for Wireless Mesh Network Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless mesh networks face interference issues due to self-interference, which limits air-time availability and efficiency, and existing methods of capping data throughput are not adaptive, unfairly restricting devices that do not contribute to interference.
Innovation Solution
Implement a method where wireless nodes monitor air-time availability and adaptively cap data throughput of client devices based on their air-time per bit efficiency, ensuring that only devices causing interference have their throughput capped, thereby optimizing air-time utilization without burdening non-contributory devices.

1Object-generated harmful factors
If a fixed cap is placed on data throughput of all client devices, then self-interference is limited, but throughput of non-interfering devices is unnecessarily restricted
Solution Approach 1:
The patent applies local quality by differentiating treatment based on individual device characteristics. Instead of uniformly capping all devices, the system monitors air-time per bit efficiency for each device and applies caps selectively only to devices exceeding thresholds, thereby reducing harmful interference from problematic devices while preserving throughput for well-behaved devices.
Solution Approach 2:
The patent implements dynamics by transitioning from static fixed caps to adaptive, real-time adjustments. The system continuously monitors air-time per bit efficiency and dynamically adjusts throughput caps based on current network conditions and individual device performance, allowing caps to increase or decrease as needed to maintain optimal network health.
2Device complexity
If fixed caps are applied to all client devices, then interference control is simplified, but network efficiency is reduced due to unnecessary restrictions
Solution Approach 1:
The system moves from uniform treatment to differentiated management by monitoring individual device air-time per bit efficiency. Devices are locally evaluated and managed according to their specific performance characteristics, applying caps only where necessary to maintain network efficiency without over-restricting well-performing devices.
Solution Approach 2:
The patent implements feedback mechanisms where the system continuously monitors air-time per bit efficiency for each device and uses this information to adjust throughput caps in real-time. This closed-loop approach ensures that interference control adapts to actual device behavior, maintaining network efficiency while preventing harmful interference.
3Productivity
If adaptive caps are applied based on air-time per bit efficiency, then throughput is optimized for non-interfering devices, but monitoring and control complexity increases
Solution Approach 1:
The patent applies self-service by having devices autonomously manage their own throughput based on monitored air-time per bit efficiency. Each device is evaluated on its own performance metrics, and self-regulating caps are applied without requiring complex centralized control, thereby reducing overall system complexity while maintaining optimized throughput.
