Sensor Network Node Device Grouping via Common Identifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing network systems, sensor devices face difficulties in connecting to node devices due to individual network identifiers, requiring a cumbersome registration process and time-consuming searches, which increases power consumption and complicates management.
Innovation Solution
Implementing a network system where node devices have a common network identifier and a connection configuration list for sensor devices to request connections, with a connection approval/disapproval determination section to establish and manage connections based on this list, allowing sensor devices to connect quickly and efficiently without searching for specific node devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each sensor terminal has an individual network identifier, then the node device can be uniquely identified in the network, but the sensor device must perform a troublesome registration process and time-consuming search to connect to the node device
Solution Approach 1:
Multiple node devices share a common network identifier, allowing any node device to be identified by the same identifier. This universal identifier enables sensor devices to connect to any node device without individual registration, as the common identifier represents all node devices in the network.
Solution Approach 2:
The connection configuration list acts as an intermediary mechanism that stores pre-configured mapping relationships between sensor devices and node devices. This intermediary structure eliminates the need for real-time search and registration processes, as connections are established based on pre-stored configurations.
2Measurement precision
If each sensor terminal has an individual network identifier, then network identification is precise, but the sensor device spends time searching for the specific node device in the connection area
Solution Approach 1:
The common network identifier serves as a universal key that points to multiple node devices simultaneously. Instead of searching for a specific node with a unique identifier, the sensor device uses the common identifier to access any node device, dramatically reducing search time while maintaining identification accuracy through the configuration list.
Solution Approach 2:
The connection configuration list is pre-populated with mapping relationships between sensor devices and node devices before actual connection occurs. This preliminary configuration eliminates the need for real-time search operations, as the necessary connection information is already prepared and stored.
3Reliability
If sensor devices perform registration and search processes to connect to node devices, then proper connection can be established, but power consumption increases
Solution Approach 1:
Connection configurations are pre-established and stored in the connection configuration list before the sensor device needs to connect. This eliminates the need for power-intensive registration and search operations during actual connection, as the sensor device only needs to retrieve pre-configured information.
Solution Approach 2:
The connection configuration list serves as an intermediary that provides connection information without requiring the sensor device to perform exhaustive search or registration procedures. This intermediary approach reduces the computational and energy costs associated with establishing connections.
4Reliability
If individual network identifiers are used for each node device, then network security can be maintained, but the management and configuration of sensor devices becomes complex
Solution Approach 1:
The common network identifier provides a unified access point that works across all node devices. This universal approach simplifies configuration management, as administrators only need to manage one identifier and the connection configuration list rather than tracking multiple unique identifiers and their associated security settings.
Solution Approach 2:
The connection configuration list acts as an intermediary management layer that handles the complexity of node device identification and connection. This intermediary structure abstracts away the complexity of individual node identifiers, making system management simpler while maintaining security through controlled access via the configuration list.

AI summary
A network system has a computer device, and a plurality of node devices communicatively connected to the computer device via network with one or more sensor devices allowed to be connected to each of the plurality of node devices via wireless communication. Each of the node devices obtains sensor data from the sensor device which is connected to the node device itself via the wireless communication and saves the sensor data in a sensor data storage section incorporated in the node device itself. The computer device specifies and requests via the network sensor data that any one or more of the one or more sensor devices obtained, and obtains via the network the specified sensor data from the node device which has saved the specified sensor data in the sensor data storage section among the plurality of node devices.
