Wireless Device Load Balancing via Antenna Power Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network congestion occurs due to uneven distribution of users among access points with different power magnitudes, leading to some access points becoming overloaded while others remain idle.
Innovation Solution
A load balancing method for wireless communication devices that involves checking the total loading of omni and directional antennas and adjusting transmission power based on this loading and information from neighboring devices to redistribute the load and alleviate congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users connect to access points based on power magnitude or preference, then connection flexibility is improved, but network congestion occurs at specific access points
Solution Approach 1:
The system implements feedback mechanisms where access points continuously monitor their loading status and transmit this information to wireless communication devices. Devices receive loading status from multiple access points and use this feedback to dynamically select the most appropriate access point, preventing congestion while maintaining connection flexibility.
Solution Approach 2:
The access point selection process transitions from static (based only on power magnitude or user preference) to dynamic, where devices continuously evaluate real-time loading status information from multiple access points and adjust their connections accordingly, optimizing network throughput while maintaining adaptability.
2Area of stationary object
If access points have different power magnitudes, then coverage area is improved, but uneven load distribution occurs
Solution Approach 1:
The system applies local quality by having different access points with different power magnitudes serve different coverage areas, while simultaneously implementing load balancing mechanisms that adjust transmission power and redirect users based on local loading conditions, ensuring uniform load distribution across the entire network.
Solution Approach 2:
The system dynamically changes parameters including transmission power levels and user redirection decisions based on real-time loading status information. Access points adjust their transmission power and the system redirects users to underutilized access points, maintaining both coverage area and load distribution uniformity.
3Area of stationary object
If transmission power is increased to expand coverage, then coverage area is improved, but network congestion worsens
Solution Approach 1:
The system performs preliminary actions by having access points proactively transmit their loading status information to wireless communication devices before users attempt to connect. This allows users to select access points with adequate capacity in advance, preventing congestion while maintaining expanded coverage through appropriate transmission power levels.
