Parent Node Reconnection via Stored Child Identifiers

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In personal area networks, orphaned child nodes need to rediscover parent nodes to reestablish connections, which consumes time and resources, as current methods require repeating the association process upon connection loss or severance.

Innovation Solution

A device with a control module and persistent storage, such as a trusted platform module, stores an identifier for each child node upon initial connection, allowing the parent node to reestablish the connection directly without the child node repeating the association process, thereby reducing the time and resource consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the child node repeats the association process to rediscover the parent node after connection loss, then the network connection can be reestablished, but time and resources are consumed

Engineering Contradiction:

Improvenetwork connection reestablishmentVSAvoidrediscovery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The parent node performs preliminary action by storing the child node's identifier in persistent storage during the initial association process. This pre-stored information enables the parent node to proactively initiate reconnection without waiting for the child node to perform full rediscovery, thereby reducing reconnection time while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the child node repeats the association process to rediscover the parent node, then connection can be restored, but resource consumption increases

Engineering Contradiction:

Improvenetwork connection reestablishmentVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the parent node stores child node identifiers in persistent storage, then reconnection speed improves, but device complexity increases

Engineering Contradiction:

Improvereconnection speedVSAvoidstorage and control module complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The persistent storage component serves multiple functions: it stores child node identifiers for fast reconnection, maintains network configuration data, and preserves association information. This multi-functionality justifies the added complexity by providing broader system benefits beyond just reconnection speed improvement

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

In embodiments, a device may include a storage device, a wireless transceiver to send and receive data, and a control module coupled with the storage device and the wireless transceiver. In embodiments, the control module may establish a network connection, via the wireless transceiver, with a child node in response to an association request received from the child node. The control module may then store an identifier associated with the child node in the storage device to enable the network connection to be reestablished with the child node in the event that the network connection with the child node is lost. Other embodiments may be described and/or claimed.
