1Area of stationary object
If a single relay device is used in the wireless communication link, then the device complexity is reduced, but the coverage distance and area are limited, making comprehensive coverage enhancement and blind spot compensation difficult
Solution Approach 1:
The patent divides the wireless communication network into multiple relay nodes (first relay node, second relay node, etc.) that operate semi-independently. Each relay node maintains its own topology information and communicates with the network device separately, segmenting the overall network management into manageable units that collectively expand coverage area while keeping individual node complexity low
Solution Approach 2:
The patent introduces topology information as an additional dimensional parameter for relay node management. By maintaining and updating topology information that describes the relationships between relay nodes and the network device, the system enables multi-hop communication paths through multiple dimensions of network connectivity, thereby expanding coverage area without proportionally increasing operational complexity
2Reliability
If multiple relay nodes are deployed to expand coverage area, then comprehensive signal coverage enhancement is achieved, but the information interaction and management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where relay nodes send interaction information (including topology information) to the network device, which then determines and returns updated topology information. This feedback loop ensures that all relay nodes maintain accurate topology information about the network structure, enabling reliable multi-hop communication while systematically managing the information required for multiple nodes
Solution Approach 2:
Each relay node autonomously maintains its own topology information based on interactions with the network device and other relay nodes. The nodes self-update their understanding of network topology through localized information exchange, reducing the burden on centralized management and minimizing information loss across the distributed network
