Wireless Channel Usage Coordination via Trusted Network Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, overlapping frequency bands between multiple networks can lead to performance degradation due to interference, and existing methods lack effective mechanisms for reliable channel usage information sharing and coordination.
Innovation Solution
A network management system is introduced to manage channel usage across wireless networks, providing channel usage information and ensuring that devices operate on non-overlapping channels by authenticating trusted sources and using encryption keys to secure this information, thereby preventing interference and improving spectral efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless networks operate on overlapping frequency bands, then network coverage and frequency utilization are improved, but interference between networks increases and performance degrades
Solution Approach 1:
The patent introduces a network management system as an intermediary that coordinates channel usage across multiple wireless networks. This mediator collects channel usage information from participating networks, processes it centrally, and distributes coordinated channel assignments back to the networks, thereby enabling overlapping frequency band utilization while preventing interference through centralized control
Solution Approach 2:
The system implements feedback mechanisms where networks report their current channel usage status to the network management system. The NMS processes this feedback information and adjusts channel assignments dynamically based on the reported usage patterns, creating a closed-loop control system that adapts to changing network conditions and maintains optimal performance
2Productivity
If channel usage information is shared between wireless networks, then coordination and interference reduction are improved, but security risks and information reliability issues worsen
Solution Approach 1:
The patent applies preliminary anti-action by implementing authentication and encryption mechanisms before channel usage information is shared between networks. The network management system verifies the authenticity of participating networks and encrypts the shared information, preventing unauthorized access and ensuring information integrity before coordination occurs
Solution Approach 2:
The system changes the security parameters of information exchange by introducing encryption keys and authentication credentials. These parameter changes transform the information sharing process from unsecured to secured, enabling reliable coordination while maintaining information confidentiality and verifying source authenticity
