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

VSEngineering 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

Engineering Contradiction:
Improveintelligent discovery capabilityVSAvoidnetwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If wireless nodes broadcast detailed service information including user models, then correlation-based link establishment becomes possible, but information transmission overhead increases

Engineering Contradiction:
Improvelink establishment accuracyVSAvoidinformation overhead
Core Design Contradiction:
ReliabilityVSLoss of information

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #26Copying

3Reliability

If nodes continuously monitor and reestablish links as they move, then connection reliability is maintained, but energy consumption increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnode energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

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.

Inventive Principle:
Principle #19Periodic action

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.
