Wireless Node Migration Sequencing for Topology-Safe Centralization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no well-defined method to transition an existing distributed wireless network to a centralized network without redeploying the entire network, and critical nodes leaving early can result in other nodes becoming unreachable during the migration.
Innovation Solution
A method involving a bridge device that collects topology information, determines a sequence list based on this information, and requests nodes to join the centralized network in a specific order to ensure a smooth transition, using parameters like network ID and operation channel, and optionally restoring node configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nodes migrate to centralized network without topology consideration, then migration speed is improved, but network reliability deteriorates due to unreachable nodes
Solution Approach 1:
The patent applies preliminary action by collecting topology information and determining migration sequences before the actual migration process. The bridge device queries topology information from all nodes and calculates a migration sequence list that ensures parent nodes migrate before child nodes, preventing connectivity loss during transition.
Solution Approach 2:
The migration process is segmented into distinct phases: topology information collection, migration sequence determination, and staged migration execution. Nodes are migrated in discrete steps according to their position in the topology tree, with the bridge device controlling each migration event individually based on the pre-calculated sequence.
2Loss of time
If distributed network is migrated to centralized network without redeployment, then loss of time is reduced, but manufacturing precision deteriorates due to lack of standardized migration procedure
Solution Approach 1:
The patent changes the parameter of network architecture from distributed to centralized while maintaining other parameters like node functionality and communication protocols. The bridge device manages this parameter change by coordinating node migrations individually, ensuring each node transitions properly without requiring complete redeployment of the network.
Solution Approach 2:
The bridge device serves as an intermediary that manages the migration process from distributed to centralized architecture. It collects topology information, determines migration sequences, and controls the transition of individual nodes, providing a standardized procedure that eliminates the need for complete network redeployment.
3Productivity
If router nodes leave distributed network early to enable centralized network formation, then centralized network setup is accelerated, but connectivity for end nodes deteriorates
Solution Approach 1:
The patent applies preliminary action by collecting complete topology information and determining the migration sequence before any node actually migrates. This ensures that parent nodes are identified and scheduled to migrate before their child nodes, preventing connectivity loss while still enabling efficient centralized network formation.
Solution Approach 2:
The bridge device uses feedback from topology information queries to dynamically determine the migration sequence. By continuously monitoring the network topology and node relationships, the system adjusts the migration order to ensure that nodes maintaining connectivity (parent nodes) migrate before nodes that depend on them (child nodes).
