Relay Communication Announcement Frame for Link Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems face challenges in maintaining reliable data pathways due to high pathloss and directional antennas, as keeping multiple relays active consumes excessive power and is inefficient.
Innovation Solution
Implementing a system that sets up multiple backup relay links with standby nodes that can quickly activate and reduce power consumption by using a Relay Communication Announcement frame to manage relay nodes' activation and deactivation, allowing only necessary nodes to remain active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple relay nodes are kept active to ensure communication reliability, then link reliability is improved, but power consumption increases
Solution Approach 1:
The system pre-establishes backup relay links and maintains standby relay nodes in a low-power state before they are needed. When the primary relay link fails, the standby nodes can quickly activate and take over, ensuring continuous communication without requiring constant activation of multiple relays, thus reducing overall power consumption while maintaining reliability
Solution Approach 2:
The relay node activation state is dynamically adjusted based on communication needs. Standby relay nodes transition between active and inactive states according to the operational status of primary relays, allowing the system to optimize power consumption by keeping nodes inactive until required while ensuring rapid response when link failure occurs
2Reliability
If standby relay nodes are activated quickly to maintain communication continuity, then link reliability is improved, but activation time and system complexity increase
Solution Approach 1:
Standby relay nodes perform preliminary configuration and maintain connection parameters in advance. When activation is required, they can immediately begin relaying communications without needing to establish new connections or configure parameters during the crisis, significantly reducing activation time while ensuring communication continuity
Solution Approach 2:
The system introduces a controller that manages the activation process of standby relay nodes. The controller coordinates the switching between primary and standby relays, streamlining the activation procedure and reducing the time required for standby nodes to become operational, thereby maintaining communication continuity without excessive delay
3Reliability
If multiple backup relay links are established, then link reliability is improved, but device complexity increases
Solution Approach 1:
The system pre-configures backup relay links with all necessary routing information and connection parameters before they are needed. This preliminary setup allows standby relays to activate immediately with minimal configuration, reducing the operational complexity of managing multiple backup links while maintaining the reliability benefits of having redundant paths
4Adaptability or versatility
If relay nodes operate beyond scheduled periods to extend coverage, then adaptability is improved, but power consumption increases
Solution Approach 1:
The system dynamically extends relay operation beyond scheduled periods when communication needs require it. Standby relay nodes can be activated on-demand outside their scheduled operational windows, providing flexible coverage extension without requiring all relays to continuously operate, thus maintaining adaptability while controlling power consumption through selective activation
