Adaptive WLAN QoS Scheduling for Time-Sensitive Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks struggle to effectively manage Quality of Service (QoS) for time-sensitive applications like IoT and AR/VR due to mismatches between application performance requirements and network interface specifications, as developers often lack knowledge of hardware platforms and network characteristics.
Innovation Solution
A method is introduced where applications insert a performance descriptive element into their requests to Access Points (APs), allowing the APs to determine network characteristics and schedule data flows accordingly, using a hierarchical scheduler that prioritizes critical traffic based on performance metrics and adaptive retry rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If developers use standard network interfaces without application-specific optimization, then device compatibility is improved, but application performance requirements cannot be met
Solution Approach 1:
The network interface is segmented into two distinct components: a standard network interface layer that handles basic connectivity and compatibility, and an application-specific network characteristics layer that handles performance requirements. This segmentation allows the system to maintain compatibility through the standard layer while meeting performance needs through the application-specific layer, resolving the contradiction between versatility and complexity.
Solution Approach 2:
An intermediary mechanism is introduced that translates application performance requirements into network interface configurations. This intermediary layer sits between the application and the network interface, converting high-level performance needs into specific network parameters without requiring developers to directly manage complex hardware details, thus maintaining both performance and compatibility.
2Productivity
If network interfaces are optimized for specific applications, then application performance is improved, but compatibility with different hardware platforms is reduced
Solution Approach 1:
The network interface is designed with multi-functionality to handle both standard connectivity tasks and application-specific performance requirements. By integrating universal compatibility features with application-optimized features in a single interface, the system can adapt to different hardware platforms while maintaining high data transmission efficiency for time-sensitive applications.
Solution Approach 2:
The system dynamically changes network interface parameters based on application requirements and hardware platform characteristics. Instead of creating fixed optimized interfaces for each application, the interface parameters (such as buffer sizes, transmission intervals, and priority levels) are adjusted according to the specific performance needs and hardware capabilities, achieving both high productivity and broad compatibility.
3Ease of operation
If developers lack knowledge of hardware platforms and network characteristics, then ease of development is improved, but QoS configuration accuracy deteriorates
Solution Approach 1:
The system implements self-service by automatically detecting hardware platform characteristics and network conditions, then autonomously configuring appropriate QoS parameters. Instead of requiring developers to manually configure complex network settings, the system performs self-diagnosis and self-configuration based on the application's performance requirements and the underlying hardware characteristics, maintaining both ease of operation and configuration accuracy.
Solution Approach 2:
A feedback mechanism is established that continuously monitors network performance and hardware status, then adjusts QoS configurations accordingly. The system receives feedback about actual network conditions and application performance, uses this information to refine QoS settings, and maintains optimal configuration accuracy without requiring developer intervention or deep hardware knowledge.

AI summary
Method for application control and Quality of Service (QoS) handling may be provided. A request may be received for scheduling a communication between an Access Point (AP) and a user device for sending data of an application. It may be determined that the request does not comprise network characteristics of the application. In response to determining that the request does not comprise the network characteristics of the application, the network characteristics may be requested from a Wireless Local Area Network (WLAN) controller. The network characteristics may be received from the WLAN controller. Schedules for the application may be determined based on the network characteristics. The schedules may be enabled.
