Wireless Mesh Node Gateway Selection and Dynamic Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks have limited adaptability and efficiency in routing data, often requiring manual configuration and adjustments due to static network topologies, which can lead to difficulties in responding to changes such as node failures or changes in user location, and inefficient traffic routing.
Innovation Solution
A wireless mesh network system where each node can automatically detect and appoint itself as a gateway, dynamically update routing tables, and self-heal by identifying and prioritizing paths based on signal strength and number of hops, allowing for adaptive and efficient data routing without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If predetermined network configurations and topologies are used, then network structure is simplified and ease of manufacture is improved, but adaptability to changing circumstances deteriorates
Solution Approach 1:
The patent implements dynamic gateway selection where nodes can automatically appoint and unappoint gateways based on real-time network conditions. The system transitions from static predetermined configurations to dynamic adaptive routing, allowing the network topology to change automatically in response to node failures, traffic patterns, or environmental conditions without manual reconfiguration.
2Measurement precision
If manual selection of gateway nodes is required, then control precision is improved, but ease of operation deteriorates and productivity decreases
Solution Approach 1:
The patent implements self-service automatic gateway appointment mechanisms where nodes autonomously detect gateway status, appoint new gateways when needed, and unappoint failed gateways without human intervention. The system automatically monitors network conditions, detects node failures, and reconfigures routing paths, eliminating the need for manual gateway selection while maintaining optimal network performance.
3Device complexity
If static routing paths are used, then device complexity is reduced, but reliability under changing conditions deteriorates
Solution Approach 1:
The patent implements feedback-driven routing where nodes continuously monitor network conditions including signal strength, node availability, and traffic patterns. Based on this feedback, the system dynamically adjusts routing paths, appoints alternative gateways when primary gateways fail, and optimizes data transmission routes to maintain reliable connectivity despite changing network conditions or node failures.
4Device complexity
If inefficient traffic routing is used, then device complexity is reduced, but productivity and speed deteriorate
Solution Approach 1:
The patent implements intelligent routing that dynamically changes transmission parameters including path selection, gateway appointment, and route optimization based on real-time network conditions. The system monitors signal strength, traffic load, and node performance metrics, then adjusts routing decisions to maximize data transmission speed and efficiency while maintaining manageable device complexity through automated decision-making algorithms.

AI summary
A wireless mesh network may have a plurality of nodes, each of which is able to dynamically establish itself as a gateway when a connection with an end-user device is detected. To route data to an end-user device, each node that is not, itself, a gateway to that device may route traffic along a path to the appropriate gateway. If a node does not have such a path in memory, it may broadcast an inquiry to all nodes with which communicates directly, to determine whether any of those nodes are a gateway to the end-user device, or have a path to the end-user device in memory. Thus, paths to gateways may propagate among the nodes. If multiple paths are available, a node may select the path that provides the best data transmission. Each node may replace pathways that are no longer valid, allowing the network to repair itself if needed.
