Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mesh networks, such as Mesh Wi-Fi, suffer from packet forwarding delays and reduced transmission rates, making them unsuitable for high immediacy networks, and excessive nodes can degrade bandwidth capacity.
Innovation Solution
A method involving a master router that calculates and selects optimal transmission paths using Dynamic Source Routing (DSR) and Ultra-Wideband (UWB) devices, adjusting paths to include UWB nodes based on detected devices and client location, and instructing clients to move to optimal UWB nodes for improved data transmission.

Engineering Contradiction Analysis
1Reliability
If packets are forwarded through multiple router nodes in a mesh network, then network coverage and reliability are improved, but transmission delay increases significantly
Solution Approach 1:
The system pre-calculates and stores multiple optimal transmission paths between router nodes before actual data transmission occurs. When a client requests data, the pre-computed paths enable immediate routing decisions without real-time calculation delays, thus maintaining reliability through path redundancy while minimizing transmission delay.
Solution Approach 2:
The routing system dynamically selects transmission paths based on real-time network conditions such as current load, node availability, and signal quality. This dynamic adaptation allows the system to choose the fastest available path while maintaining reliability through automatic rerouting if the optimal path becomes unavailable.
2Reliability
If more router nodes are added to the mesh network, then network coverage and redundancy are improved, but transmission rate decreases due to bandwidth sharing
Solution Approach 1:
The network traffic is segmented and routed through different paths simultaneously using multiple transmission channels. By dividing the data flow and distributing it across multiple nodes and paths, the system maintains high transmission rates while utilizing the redundancy of multiple nodes for reliability.
Solution Approach 2:
The system changes routing parameters such as path selection, node selection, and transmission timing based on network conditions. By dynamically adjusting these parameters, the system optimizes transmission rate while maintaining the redundancy benefits of having multiple nodes in the network.
3Area of stationary object
If packets are forwarded through many router nodes, then network coverage is improved, but bandwidth capacity is degraded
Solution Approach 1:
The system utilizes multiple dimensions of network resources including spatial diversity (different physical paths), temporal diversity (different transmission times), and frequency resources. By operating in multiple dimensions simultaneously, the system achieves extensive network coverage while maintaining bandwidth capacity through parallel transmission channels.

AI summary
A transmission path improving method in a mesh network is disclosed. General transmission paths connecting to each of routers and Ultra-Wideband (UWB) transmission paths connecting to each of UWB devices are calculated. If a client is located within a detection range of a UWB device, an optimal transmission path relating to the UWB device is selected from the UWB transmission paths and the optimal transmission path is transmitted to the client.
