Wireless Network Connection Management Using Signal Strength and Bandwidth Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks like Wi-Fi, existing methods lead to inefficient resource utilization as stations often connect to access points with the strongest signal, causing overload and reduced resource availability for other nearby access points, resulting in suboptimal network performance.
Innovation Solution
A method where stations and access points use signal strength and bandwidth threshold criteria to determine optimal access point connections, with stations sending normal or prioritized requests based on availability, and access points adjusting bandwidth allocation to accommodate new connections while maintaining service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stations connect to access points with the strongest signal, then signal strength is maximized, but network resource utilization becomes inefficient due to overload on certain access points
Solution Approach 1:
The patent changes the connection decision parameters by introducing bandwidth availability thresholds and service quality metrics beyond just signal strength. Stations evaluate multiple parameters including current bandwidth usage, available capacity, and predicted service quality before selecting an access point, transforming the single-parameter (signal strength) decision into a multi-parameter optimization problem that balances load distribution across the network
Solution Approach 2:
The system dynamically adjusts access point selection criteria based on real-time network conditions. Access points continuously monitor their bandwidth utilization and adjust their acceptance thresholds dynamically, allowing the network to adapt to changing traffic patterns and maintain optimal resource distribution. This dynamic behavior enables the system to respond to overload conditions by redirecting stations to less congested access points even when signal strength is slightly lower
2Ease of operation
If access points accept all connection requests, then ease of operation is improved, but service quality deteriorates due to resource overload
Solution Approach 1:
The patent implements a feedback mechanism where access points monitor their bandwidth utilization and communicate availability status to stations. Stations receive feedback about current network conditions and adjust their connection decisions accordingly. This feedback loop enables the system to maintain service quality by preventing connections that would cause overload, while still preserving ease of operation through automated decision-making that presents a unified interface to users
Solution Approach 2:
The system takes preliminary anti-action by proactively evaluating connection requests against bandwidth thresholds before accepting them. Access points assess available capacity in advance and reject or redirect requests that would compromise service quality, preventing overload conditions before they occur. This anticipatory approach maintains reliability by avoiding resource exhaustion while keeping the system easy to operate through automated rejection or redirection of unsuitable connections
3Reliability
If bandwidth allocation is optimized for existing connections, then service quality is maintained, but adaptability to new connections is reduced
Solution Approach 1:
The patent applies partial action by allocating bandwidth reserves in advance to potential new connections. Access points maintain unused bandwidth capacity above the minimum threshold, creating a buffer that can be quickly allocated to new stations without disrupting existing connections. This partial allocation strategy maintains service quality for current users while providing the adaptability needed to accommodate new connections flexibly
Solution Approach 2:
The system performs preliminary action by pre-evaluating and reserving bandwidth capacity for potential new connections before they actually occur. Access points continuously assess their capacity headroom and prepare allocation plans in advance, enabling rapid onboarding of new stations. This preliminary preparation maintains service quality by ensuring existing connections have guaranteed bandwidth while simultaneously improving adaptability to new connections through pre-configured allocation strategies

AI summary
A method for establishing communication between a station (100) and an access point (110) in a wireless network, the method comprising the steps of: at the station (100): measuring (301) a received signal strength (AP_RSSI) of the access point (110); and sending (303) to the access point (110) a connection request and the AP_RSSI; at the access point (110): receiving (304) the connection request and the AP_RSSI from the station (100); measuring (305) a received signal strength (S_RSSI) of the station (100); determining (306) whether the AP_RSSI and the S_RSSI are above a threshold and whether the access point (110) has sufficient bandwidth available to communicate with the station (100) and: if so, sending an acceptance of connection request to the station (100) to continue (307) communication with that station and if not, sending a denial of connection request to the station (100).
