Wireless Access Point Association Timing Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face increased network loading and decreased data throughput due to communication of aggregate services, beaconing, and messaging, which results in collisions and inefficiencies in collision avoidance schemes.
Innovation Solution
A processing system determines a time period during which an access point is accessible and generates messages to establish associations, allowing devices to request and confirm accessibility, thereby optimizing network connections and reducing collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aggregate services, beaconing, and messaging are communicated in wireless networks, then service discovery and device coordination are enabled, but network loading increases and data throughput decreases
Solution Approach 1:
The patent applies preliminary action by having devices advertise their services and availability in advance through beacon frames and capability negotiation messages. This allows receiving devices to plan their communication needs ahead of time, reducing real-time collisions and improving throughput by pre-coordinating service interactions.
Solution Approach 2:
The patent implements feedback mechanisms where devices exchange capability information, availability status, and service advertisements in a structured manner. This feedback loop enables devices to adjust their behavior based on network conditions and service availability, optimizing the balance between service discovery and data throughput.
2Reliability
If collision avoidance schemes are implemented to prevent packet collisions, then communication reliability improves, but network loading increases
Solution Approach 1:
The patent uses preliminary action by implementing capability negotiation and availability announcement before actual data transmission. Devices exchange information about their service capabilities and availability status in advance, allowing them to schedule communications more efficiently and reduce collisions, thereby improving reliability without excessive network loading.
Solution Approach 2:
The patent segments the communication process into distinct phases: service advertisement, capability negotiation, and data transmission. This segmentation allows collision avoidance mechanisms to operate more effectively by separating the coordination phase from the data phase, reducing the overhead impact on network loading.
3Adaptability or versatility
If devices advertise all available services over the wireless network, then service discoverability improves, but computational overhead and messaging increase
Solution Approach 1:
The patent extracts only the essential service information needed for discovery and coordination, rather than advertising all possible service details. By taking out only the critical capability parameters and availability status, the system maintains good service discoverability while significantly reducing the computational overhead and messaging burden.
Solution Approach 2:
The patent applies partial action by advertising only the necessary service capabilities and availability information required for basic coordination, rather than all possible service details. This partial advertising approach maintains sufficient service discoverability for most applications while minimizing the overhead associated with complete service enumeration.
Data Source
AI summary
Systems and methods for establishing associations on a wireless network, where the associations require a device to be available to the requesting device for a portion of time within a maximum time away period, are disclosed. In one aspect, a method includes determining, by the apparatus, of a time period during which the access point can be accessible to the apparatus, the generating of a message identifying the time period, and the transmitting of the generated message to another apparatus.
