Dynamic Scan Duration Control for Wireless Advertising
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks, devices face challenges in efficiently scanning for advertising packets due to interference from other operations, leading to reduced scanning quality and inefficient resource usage, as existing methods do not dynamically adjust scan duration based on real-time conditions.
Innovation Solution
A dynamic scan duration control system that monitors interruptions during scanning and extends the scan duration accordingly, ensuring sufficient time for scan operations while preventing unnecessary resource usage by adapting to changing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device performs scanning for advertising packets, then device discovery capability is improved, but resource usage and power consumption increase
Solution Approach 1:
The patent implements dynamic scan duration adjustment where the scanning operation adapts its duration based on real-time conditions. The scan duration is extended when interruptions are detected and reduced when no interruptions occur, making the power consumption and discovery capability dynamic rather than fixed, thus resolving the contradiction between reliable device discovery and power consumption
Solution Approach 2:
The patent changes the scan duration parameter dynamically based on detected interruptions. By adjusting this key parameter according to actual scanning conditions, the system optimizes the balance between discovery capability and power consumption, moving from a static parameter approach to a dynamic one that adapts to real-time needs
2Reliability
If scan duration is extended to ensure sufficient scanning time, then scanning quality is improved, but resource usage increases unnecessarily
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors scanning conditions and interruption status, then adjusts scan duration accordingly. This closed-loop control ensures that scan duration is extended only when necessary to maintain scanning quality, preventing unnecessary resource usage while ensuring adequate scanning time when interruptions occur
Solution Approach 2:
The scan duration is made dynamic rather than fixed, allowing the system to adapt scanning time to actual conditions. This dynamic adjustment ensures scanning quality is maintained when needed while avoiding excessive resource usage when conditions are favorable, resolving the contradiction between quality and time efficiency
3Device complexity
If fixed scan duration is used, then system complexity is reduced, but scanning performance deteriorates under interference
Solution Approach 1:
The patent introduces a feedback-based scan duration adjustment mechanism that monitors interruption status and adapts scan duration accordingly. This feedback loop improves scanning performance under interference conditions without significantly increasing system complexity, as the adjustment logic is triggered only when interruptions are detected
Solution Approach 2:
The patent dynamically changes the scan duration parameter based on detected interruptions, improving scanning performance when interference occurs. This parameter adjustment approach maintains relatively simple system architecture while enabling adaptive performance optimization, resolving the contradiction between complexity and performance
