Wireless Channel Selection via Group Segmentation and State Querying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless channel selection methods lead to channel congestion when multiple devices automatically select the same channel, resulting in degraded user experience and reduced communication quality due to the finite number of available channels and the lack of effective congestion avoidance mechanisms.
Innovation Solution
A method where wireless devices are grouped and one device within each group acts as a channel selection device, scanning and querying adjacent devices to determine if they are in an automatic channel selection state, switching to a waiting state if any are active, and only proceeding with channel selection after ensuring all adjacent devices have completed their selection, thereby avoiding simultaneous channel selection and congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple wireless devices execute automatic channel selection simultaneously, then each device can independently select a channel, but channel congestion occurs and user experience is degraded
Solution Approach 1:
The system segments adjacent wireless devices into groups, with each group electing a single channel selection device. This segmentation prevents multiple devices in the same geographic area from simultaneously selecting channels, thereby avoiding channel congestion while maintaining automatic selection functionality.
Solution Approach 2:
The channel selection device acts as an intermediary for its group, performing channel selection on behalf of all adjacent devices in the group. This intermediary approach coordinates channel selection across multiple devices, preventing simultaneous selections that would cause congestion.
2Stability of the object's composition
If a wireless device successfully executes automatic channel selection, then the device can maintain stable operation, but the device enters an endless loop of channel congestion when multiple devices select the same channel
Solution Approach 1:
The system performs preliminary coordination by having devices query the channel selection status of adjacent devices before executing channel selection. This preliminary action prevents multiple devices from simultaneously entering the selection process, avoiding the endless loop of congestion while maintaining stability.
3Productivity
If wireless devices use the same finite number of wireless channels, then channel resources are efficiently utilized, but channel congestion occurs when multiple devices choose the same channel
Solution Approach 1:
By segmenting devices into groups with single channel selection devices, the system distributes channel selection authority across multiple geographic segments. This segmentation allows efficient utilization of finite channel resources while preventing congestion through coordinated selection across segments.

AI summary
The invention discloses a wireless device and a channel selection method thereof, comprising: Step S1, a channel selection device launches into an operating state; Step S2, the channel selection device scans adjacent access devices and sends a state query request; Step S3, the channel selection device judges whether any adjacent access device is in the operating state by feedback information for the state query request; if the result shows "No", turning to Step S5; Step S4, the channel selection device switches into a waiting state, and returning to Step S2 after a predefined first delay; and Step S5, the channel selection device maintains in the operating state, and executes an automatic channel selection, then exits. The problem of channel selection by a plurality of neighboring wireless devices is solved; a channel congestion problem is relieved; the connection quality of the wireless network is improved; and the user experience is upgraded.
