Mesh Network Pairing Switching with Refugee Table Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh networks face inefficiencies in switching pairing between nodes, leading to delayed updates in routing tables and network topology changes.
Innovation Solution
A method for switching pairing in a mesh network system involves a network node performing a scanning procedure to select a new parent node, generating and sending specific packets to update refugee tables, ensuring fast and stable pairing by managing MAC addresses and relay services across nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a node disconnects from current parent node first, then selects a new parent node to connect, then updates routing table, then pairing switching can be completed, but the pairing switching time is prolonged and network topology update is delayed
Solution Approach 1:
The patent applies preliminary action by having the network node select and prepare a new parent node through scanning procedure before actually disconnecting from the current parent node. The node performs the scanning procedure to identify suitable parent nodes in advance, so when switching is needed, the node can quickly connect to the pre-identified new parent node without prolonged disconnection time.
Solution Approach 2:
The patent implements dynamics by enabling the network node to dynamically adjust its parent node connection based on real-time network conditions. The node can switch between different parent nodes by performing scanning procedures and selecting optimal parents, making the network topology flexible and adaptive rather than static, thereby reducing switching time and improving responsiveness.
2Adaptability or versatility
If different networking technologies use different methods for switching pairing, then each technology can maintain its own switching mechanism, but relevant nodes cannot obtain and update node switching information at the same time
Solution Approach 1:
The patent applies universality by creating a standardized parent node switching mechanism that can be used across different networking technologies. The scanning procedure and parent node selection method are designed to be technology-agnostic, allowing various networking protocols to benefit from the same efficient switching approach, thereby achieving both adaptability and information synchronization.
Solution Approach 2:
The patent implements feedback by having nodes broadcast and update their parent node information to relevant nodes in the network. When a node switches parent nodes, this switching information is propagated throughout the network through feedback mechanisms, ensuring that all relevant nodes receive and update their routing tables simultaneously, thus preventing information loss and maintaining network consistency.

AI summary
Disclosed is a method for switching pairing in a mesh network system, including: selecting, by a network node, a new parent node; generating and sending, by the network node, a pairing change request packet to the new parent node when the new parent node is not an access point; adding, by the new parent node, MAC addresses of the network node and its descendant nodes to a refugee table when determining that it can provide relay services; returning, by the new parent node, a first pairing approval packet to the network node when the new parent node is a root node; forwarding, by the new parent node, the pairing change request packet upstream when the new parent node is not the root node; wherein pairing switching is successful if the network node receives the first pairing approval packet.
