Multi-Hop Wireless Network Node Ignition Using Pre-Calculated Beamforming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-hop wireless networks face inefficiencies in establishing and re-establishing wireless connections between network nodes due to the lack of initial and pre-determined information about beamforming weights and orientations, leading to suboptimal connection establishment and re-ignition processes.
Innovation Solution
The implementation of a method where network nodes are installed and ignited using pre-identified locations, with a central controller guiding the ignition process by setting nodes to initiator or responder modes, adjusting beamforming weights, and utilizing GPS data to establish connections, and employing a 'warm start' approach for re-ignition using recorded statistics from previous steady-state operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network nodes adjust beamforming weights to scan for connections without pre-determined information, then network nodes can establish wireless connections autonomously, but the time required for connection establishment increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-determining beamforming weights and orientations before network node deployment. GPS data is collected during installation, and beamforming parameters are calculated in advance based on these location data. When nodes are ignited, they can immediately use these pre-calculated parameters to establish connections without time-consuming scanning, thus resolving the contradiction between autonomous operation and connection time.
Solution Approach 2:
The patent introduces GPS data as an intermediary that bridges the gap between physical node locations and communication parameters. The GPS coordinates serve as a mediator that allows the system to calculate optimal beamforming weights without requiring nodes to scan and discover each other through trial-and-error, thereby reducing connection establishment time while maintaining autonomous operation.
2Reliability
If network nodes perform full scanning to establish connections during re-ignition, then reliable connections can be established after failures or maintenance, but the re-ignition process becomes time-consuming and reduces network availability
Solution Approach 1:
The patent stores beamforming weight information and GPS data from previous steady-state operations in a database before failures occur. During re-ignition, nodes retrieve these pre-stored parameters and apply them immediately, bypassing the need for full scanning. This preliminary preparation ensures reliable re-connection while minimizing network downtime, thus resolving the contradiction between reliability and productivity.
Solution Approach 2:
The system implements feedback by continuously monitoring network node status and storing operational parameters during steady-state operation. When a failure or maintenance event occurs, the system uses the stored feedback information (beamforming weights, GPS data) to rapidly re-establish connections, ensuring both reliability and minimal disruption to network productivity.
3Loss of time
If pre-determined beamforming information is stored in network nodes, then connection establishment time is reduced, but the complexity of information management and node configuration increases
Solution Approach 1:
The patent introduces a centralized database as an intermediary that manages the complexity of storing and retrieving beamforming information. Instead of requiring complex local configuration management at each node, the database serves as a centralized repository that stores GPS data, beamforming weights, and orientation information. Nodes simply query this database for their pre-calculated parameters, which simplifies node configuration while maintaining fast ignition times.
4Adaptability or versatility
If network nodes use arbitrary installation locations without pre-identification, then deployment flexibility is improved, but connection establishment becomes less efficient and requires more scanning
Solution Approach 1:
The patent applies preliminary action by collecting GPS data during the arbitrary deployment process itself. Even though nodes are installed at flexible, pre-identified locations rather than predetermined positions, the system captures the actual location information at installation time and uses it to calculate optimal beamforming parameters before ignition. This allows deployment flexibility to be maintained while connection establishment efficiency is improved through pre-calculated parameters.
