Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multichannel Medium Access Control (MAC) technologies face challenges in supporting non-agile channel switching, particularly in unmanaged networks, and struggle to make agile and non-agile channel switching coexist without altering existing hardware.
Innovation Solution
A non-agile channelization method for multichannel MAC, where channels are categorized as agile or non-agile, and operation modes are selected to enable multichannel switching, allowing for network connectivity and coexistence with agile switching without hardware changes, utilizing a channel utilization vector to manage channel selection and operation modes like BSS-Heavy and WDS-Heavy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-agile channel switching is implemented, then network connectivity is improved, but difficulty in defining channel switching boundary increases
Solution Approach 1:
The patent introduces a channel switching boundary parameter that defines specific time points when non-agile channel switching occurs. This parameter change transforms the ambiguous switching boundary into a measurable and controllable variable, resolving the difficulty in defining channel switching boundaries while maintaining network connectivity.
2Adaptability or versatility
If non-agile and agile channel switching coexist, then hardware compatibility is maintained, but system complexity increases
Solution Approach 1:
The patent segments channels into two distinct types: non-agile channels for fixed-time switching and agile channels for flexible switching. This segmentation allows the system to support both switching modes simultaneously without requiring hardware changes, while managing complexity through clear categorization and separate handling mechanisms for each channel type.
Solution Approach 2:
The patent creates a universal channel switching framework that can handle both non-agile and agile channel switching through a common MAC layer architecture. The system uses a unified channel switching boundary parameter and operation mode selection mechanism that works across both channel types, maintaining hardware compatibility while supporting diverse switching requirements.
3Productivity
If operation modes are selected for non-agile channels, then channel switching efficiency is improved, but control complexity increases
Solution Approach 1:
The patent introduces dynamic operation mode selection for non-agile channels, where the system can switch between different operation modes (such as BSS-Heavy and WDS-Heavy modes) based on network conditions. This dynamic adaptation improves channel switching efficiency by optimizing performance for different traffic scenarios, while the mode selection is managed through standardized parameters that control complexity.

AI summary
A non-agile channelization method for multichannel medium access control (MAC) is provided, in which an available channel is categorized as an agile or non-agile channel, an operation mode of the channel categorized as the non-agile channel is selected, and multichannel switching is performed according to the selected operation mode. The non-agile channelization method for multichannel MAC enables non-agile channel switching to create a connected network, and allows agile and non-agile channel switching to coexist to avoid a change in existing hardware.
