Wireless Node Profile Correlation for Dynamic Link Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peer-to-peer wireless networks face challenges in implementing intelligent discovery and acquisition procedures that are dynamic and efficient, especially as the complexity of wireless communications grows, and there is a need for methods to establish wireless links based on correlation information between nodes.
Innovation Solution
The method involves wireless nodes broadcasting reference signals containing service and assist information, which includes user models or profiles, allowing other nodes to determine correlation and establish direct or indirect wireless links based on correlation metrics and threshold values, with the assistance of intermediary nodes if needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peer-to-peer wireless networks use traditional discovery and acquisition procedures, then nodes can establish wireless links, but the networks lack intelligent and dynamic discovery capabilities as complexity grows
Solution Approach 1:
User profiles and service information are pre-configured and stored in the wireless nodes before actual communication needs arise. This preliminary preparation enables nodes to quickly perform correlation-based discovery and acquisition without complex real-time processing, resolving the contradiction between intelligent discovery capability and network complexity.
2Reliability
If wireless nodes broadcast detailed service information including user models, then correlation-based link establishment becomes possible, but information transmission overhead increases
Solution Approach 1:
The patent extracts and broadcasts only essential correlation elements (user profile identifiers and key service parameters) rather than complete user models. This selective extraction maintains link establishment accuracy by preserving critical correlation information while significantly reducing information transmission overhead.
Solution Approach 2:
Instead of transmitting complete user models, the system uses simplified profile representations that capture essential correlation characteristics. These profile copies enable correlation-based discovery without the full information burden of complete user models, balancing reliability with information efficiency.
3Reliability
If nodes continuously monitor and reestablish links as they move, then connection reliability is maintained, but energy consumption increases
Solution Approach 1:
The system implements periodic link quality assessment and conditional reestablishment rather than continuous monitoring. Nodes perform correlation-based checks at intervals and only initiate reconnection when threshold conditions are met, maintaining connection reliability while significantly reducing energy consumption compared to continuous monitoring.

AI summary
A wireless node configured to store information, discover another wireless node by correlating the stored information with assist information from said another wireless node, and determine whether to establish a wireless link with said another wireless node based, at least in part, on the correlation.
