Distributed Relay Node Path Configuration for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication methods, particularly in wireless communication, face limitations in flexibility and scalability due to centralized control nodes, which restrict their applicability to communication networks without centralized control and hinder efficient long-distance transmission.
Innovation Solution
A communication method where a first node determines a main path and configures transmission parameters for third nodes to select between direct and relay transmission paths dynamically, based on conditions such as hop count or path loss, allowing for flexible and reliable data transmission without centralized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized control node performs configuration, then transmission reliability is ensured, but flexibility and scalability are reduced
Solution Approach 1:
The patent extracts the centralized control function from the traditional base station architecture. Instead of requiring a centralized controller to manage all relay nodes, the system enables relay nodes to autonomously determine transmission configurations based on local conditions (channel quality, traffic demand, relay node capabilities), thereby eliminating the scalability limitations of centralized control while maintaining transmission reliability through distributed decision-making
Solution Approach 2:
Relay nodes perform self-configuration and self-management by independently evaluating transmission conditions and selecting appropriate transmission modes (direct transmission, single-hop relay, multi-hop relay) without external control instructions. Each relay node uses local channel quality information and traffic demand to autonomously determine its transmission parameters, enabling the system to adapt dynamically to changing network conditions
2Length of moving object
If relay multi-hop transmission is introduced, then long-distance transmission capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the complex transmission configuration task into simple local decisions at each relay node. Instead of configuring entire multi-hop paths centrally, each relay node independently determines its own transmission mode based on local conditions (channel quality, traffic demand, relay capability), dividing the complex system into manageable autonomous units that simplify overall configuration
Solution Approach 2:
The transmission configuration is made dynamic rather than static. Relay nodes continuously adjust their transmission modes based on real-time channel quality measurements and traffic demand changes. The system can switch between direct transmission, single-hop relay, and multi-hop relay modes dynamically, allowing the network to adapt to varying conditions without requiring complex pre-configured paths
3Reliability
If centralized allocation of resources is performed, then transmission conflict is avoided, but scalability is limited
Solution Approach 1:
The patent implements feedback mechanisms where relay nodes continuously monitor local channel quality and traffic demand, using this information to adjust their transmission configurations autonomously. This feedback loop enables relay nodes to avoid transmission conflicts by adapting to real-time network conditions, eliminating the need for centralized resource allocation while maintaining scalability

AI summary
A method includes: a first node determines a main path, where the main path includes a transmission path that is between the first node and a second node and that meets a condition; determines a third node and a transmission configuration parameter based on the main path, where the third node is a node through which the transmission path between the first node and the second node necessarily passes; and sends, to the third node, the transmission configuration parameter used to determine a transmission manner between neighboring third nodes.
