Hybrid Mesh Network Loop Prevention via Wired Link Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mesh networks with both wired and wireless links face challenges in optimizing route determination and preventing loop formation, especially in partially connected networks where changes in network conditions or node failures require dynamic adjustments in routing and communication methods.
Innovation Solution
A hybrid mesh networking system where nodes can switch between wired and wireless connections based on availability and throughput, using a root node as a wired backhaul gateway to manage associations and prevent loop formation by suspending wireless communication when an Ethernet connection is established, allowing for efficient data transfer and redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication is maintained between two nodes connected by both wired and wireless links, then communication redundancy is improved, but loop formation occurs causing data transmission delays
Solution Approach 1:
The patent extracts or removes the wireless communication link between two nodes that are already connected by a wired link, preventing loop formation. When a wired connection is detected between nodes, the wireless connection between those same nodes is suspended or removed from active communication paths, thereby eliminating the harmful loop while preserving the redundant communication path through the wired connection.
2Adaptability or versatility
If routing algorithms allow packets to travel through any available link, then network flexibility is improved, but loop formation occurs resulting in continual data repetition
Solution Approach 1:
The patent applies preliminary anti-action by proactively preventing loop formation before it can occur. The system detects when two nodes are connected by both wired and wireless links and preemptively suspends the wireless communication between those nodes. This preliminary action prevents the harmful loop from forming in the first place, while still allowing the network to maintain flexibility through other available paths.
3Area of stationary object
If multiple hops are used for information transmission in partially connected networks, then network coverage is improved, but transmission complexity increases
Solution Approach 1:
The patent uses intermediate nodes as mediators to facilitate communication between nodes that are not directly connected. In partially connected networks where not all nodes have direct links, intermediate nodes relay information packets between origin and destination nodes, enabling extended network coverage while managing transmission complexity through structured multi-hop routing.
