Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of mesh network architectures makes it difficult for users to select the best networking technology, as different technologies like wired Ethernet, wireless, and power line communication have varying efficiencies, and there is a need for an automated method to determine the optimal connection.
Innovation Solution
A network node device with a communication unit and processing unit that connects to a gateway via relay nodes, determines whether uplink time parameter tables are received from relay nodes, calculates estimated uplink time parameters, and selects the best connection path based on these parameters using wireless or wired network time parameter estimation methods.

Engineering Contradiction Analysis
1Adaptability or versatility
If a mesh network architecture combines various networking technologies, then the adaptability and coverage are improved, but the device complexity and difficulty of path selection increase
Solution Approach 1:
The network node device automatically performs path selection by receiving uplink time parameter tables from relay nodes, calculating estimated uplink time parameters, and determining the optimal connection path without user intervention. This self-service mechanism resolves the complexity issue while maintaining the adaptability benefits of mesh networks.
Solution Approach 2:
Relay nodes pre-calculate and provide uplink time parameter tables to network node devices before actual data transmission. This preliminary action allows the network node to make informed path selection decisions based on pre-analyzed network conditions, simplifying the user's task while maintaining adaptability across different networking technologies.
2Ease of operation
If automatic path selection is implemented, then the ease of operation is improved, but the loss of time for parameter calculation increases
Solution Approach 1:
Relay nodes pre-calculate uplink time parameter tables in advance and store them for quick retrieval. When a network node needs to select a path, it receives these pre-computed tables and performs rapid estimation calculations, significantly reducing the time required for automatic path selection while maintaining ease of operation.
