Multi-Link Connection Reconfiguration for Wireless Network Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Control actions in wireless mesh networks, such as Wi-Fi Scan, Wi-Fi CAC, and Wi-Fi Sensing, disrupt communications between nodes using distinct frequency bands, affecting network performance and user experience.
Innovation Solution
A controller node anticipates and coordinates configuration modifications of multi-link connections before executing control actions, adapting the configuration based on the nature and impact of the action to minimize disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control actions (Wi-Fi Scan, Wi-Fi CAC, Wi-Fi Sensing) are executed on frequency bands, then network monitoring and channel management are improved, but communication disruptions and packet loss increase on multi-link connections
Solution Approach 1:
The controller node proactively identifies control actions that will disrupt communications and pre-modifies the configuration of affected multi-link connections before executing these control actions. This preliminary reconfiguration redirects data flows away from links that will experience disruptions, thereby maintaining communication reliability while allowing necessary network monitoring and channel management operations to proceed.
2Measurement precision
If control actions are executed on frequency bands, then channel availability and network performance monitoring are improved, but data transmission interruptions and latency increase
Solution Approach 1:
The system performs preliminary identification of control actions and their potential impact on data transmissions before execution. By pre-modifying configurations to redirect flows away from affected links, the system ensures that channel monitoring and availability detection can be performed accurately without causing transmission interruptions or latency increases.
3Adaptability or versatility
If multi-link connections are maintained across multiple frequency bands, then network redundancy and data transmission capacity are improved, but vulnerability to control action disruptions increases
Solution Approach 1:
When control actions are identified that will disrupt multiple frequency bands, the controller node proactively modifies the configuration of affected multi-link connections before execution. This involves redirecting data flows away from links that will experience disruptions while maintaining the overall multi-link connection structure, thus preserving network redundancy and adaptability while minimizing vulnerability to control action disruptions.
