Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless sensor network technologies, such as ZigBee and Z-Wave, cannot support the self-construction of multiple wireless networks in a desired structure, limiting the ability to separate network devices into specific networks and manage network associations and transfers effectively.
Innovation Solution
A network self-construction method where access points (APs) transmit beacon signals with association permission or non-permission information, allowing a system manager to sequentially construct multiple networks by controlling network device associations and transfers between APs, enabling desired network structures and supporting additional device associations and network healing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network devices are allowed to associate with arbitrary APs when powered on, then network association is simple and automatic, but the system manager cannot construct multiple networks in a desired structure
Solution Approach 1:
The system manager performs preliminary actions by determining the network construction order and pre-configuring APs with network device information before actual association occurs. This allows the system to maintain both automatic association simplicity and structured multiple network construction capability.
Solution Approach 2:
The system manager acts as an intermediary between APs and network devices, controlling the association process by determining which devices associate with which APs. This mediator role enables structured multiple network construction while maintaining automated association procedures.
2Manufacturing precision
If a controller manually manages each network device for network association, then precise network construction is achieved, but the system is only applicable to small-size networks and requires extensive manual effort
Solution Approach 1:
The system enables self-service by allowing the system manager to automatically determine association relationships based on pre-configured information. The APs and network devices automatically execute association according to the system manager's determined plan, eliminating the need for manual device-by-device configuration while maintaining precise network construction.
Solution Approach 2:
The system changes the parameter of association control from manual device-level parameters to automated system-level parameters. The system manager determines association relationships using automated logic based on network construction order and device information, reducing manual complexity while maintaining construction precision.
3Productivity
If multiple APs are installed in the same place and network devices are powered on simultaneously, then network deployment is fast, but network devices associate with arbitrary APs instead of specific networks
Solution Approach 1:
The system manager performs preliminary determination of network construction order and device-AP association relationships before devices are powered on. This preliminary action enables fast simultaneous deployment of multiple APs while ensuring devices associate with the correct specific networks according to the predetermined structure.

AI summary
Provided is a network self-construction method of connecting network devices to a specific network in a wireless application environment in which network devices must be divided into multiple networks in the same space. An access point (AP) controls network association of the network devices by transmitting a beacon signal into which information indicating association permission or non-permission of a network operated by the AP is inserted. A system manager associates the network devices with a specific network through the AP. When the network construction is completed, the system manager disables the AP from permitting additional network association. By repeating these steps, new networks are sequentially constructed. The system manager performs network construction by dividing the network devices into multiple networks in a desired structure and supports additional network association of network devices and transfer to other networks.
