Wireless Channel Load Aggregation for QoS Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies, such as IEEE 802.11 standards, face challenges in accurately reflecting channel load in wireless communication channels, leading to inefficient distribution of clients across different channels, which affects network performance.
Innovation Solution
Implementing a method where network devices, like access points, periodically advertise channel loads and aggregate the number of clients across multiple wireless networks using the same communication channel, allowing for accurate load information dissemination and improved client association decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IEEE 802.11e standard QBSS element is used to advertise channel load, then QoS for real-time traffic is improved, but the channel load information cannot accurately reflect the actual load of the wireless communication channel
Solution Approach 1:
The patent introduces an intermediary mechanism that aggregates channel load information from multiple access points operating on the same wireless communication channel. The QBSS element is enhanced to include aggregated load data from neighboring APs, providing a more comprehensive view of channel conditions while maintaining QoS capabilities for real-time traffic.
Solution Approach 2:
The patent merges channel load information from multiple access points into a single aggregated value that is advertised in the QBSS element. This combining of data from multiple sources provides more accurate channel load reflection while preserving the QoS functionality established by IEEE 802.11e.
2Area of stationary object
If multiple clients share the same wireless communication channel, then network coverage is improved, but network performance deteriorates due to channel competition
Solution Approach 1:
The patent implements a feedback mechanism where access points periodically advertise aggregated channel load information through enhanced QBSS elements. Clients use this feedback to make informed association decisions, selecting access points with lower channel load to maintain network performance while preserving coverage area.
Solution Approach 2:
The patent enables dynamic client distribution across multiple channels by providing real-time load information. Clients can dynamically adjust their association choices based on current channel conditions, allowing the network to adapt to changing traffic patterns while maintaining both coverage and performance.
