Universal Schema for Heterogeneous IoT Device Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices lack a standardized method to form associations and interact seamlessly with heterogeneous devices, due to differences in type, functionality, and attributes, which hinders effective communication and collaboration within IoT networks.
Innovation Solution
A universal schema is introduced that is adaptive and extensible, allowing IoT devices to determine associations based on schema elements and values, enabling interaction and collaboration among diverse IoT devices by using a generic schema that evolves with learning and environmental context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standardized association method is implemented for IoT devices, then communication efficiency and collaboration among heterogeneous devices are improved, but device complexity and implementation difficulty increase due to the need to handle diverse device types, functionalities, and attributes
Solution Approach 1:
The patent implements a universal schema framework that can represent multiple device types, functionalities, and attributes through a common set of schema elements. This allows heterogeneous IoT devices to be associated and communicate using a standardized method, improving communication efficiency while avoiding the need for device-specific association protocols. The schema elements include device identifiers, capabilities, attributes, and association rules that universally apply across different device types.
Solution Approach 2:
The patent uses parameter-based schema elements to represent device characteristics, allowing the system to handle diversity through configurable parameters rather than fixed device-specific structures. By changing and combining different schema element values (such as device type, capability sets, and attribute parameters), the system can accommodate heterogeneous devices using a consistent association framework, reducing implementation difficulty.
2Adaptability or versatility
If heterogeneous IoT devices with different types, functionalities, and attributes are integrated into the same network, then system versatility and application range are improved, but the ability to form associations and communicate seamlessly deteriorates due to lack of standardization
Solution Approach 1:
The universal schema framework provides a common language for representing diverse device characteristics, enabling reliable association formation across heterogeneous devices. The schema includes standardized elements for device identification, capability description, and association rules that work consistently regardless of device type, maintaining association reliability while supporting system versatility.
Solution Approach 2:
The patent segments device information into discrete schema elements (device identifiers, capabilities, attributes, associations) that can be independently defined and combined. This segmentation allows the system to handle heterogeneous devices by breaking down their complexity into standardized components, enabling reliable association formation through systematic comparison and matching of schema elements rather than requiring complete device compatibility.
3Adaptability or versatility
If a generic schema that evolves with learning and environmental context is used, then adaptability to new devices and scenarios is improved, but schema complexity and processing requirements increase
Solution Approach 1:
The patent implements a dynamic schema framework where schema elements and their values can evolve based on learned patterns and environmental context. The association rules can be updated and refined as the system encounters new device types and scenarios, improving adaptability without requiring complete schema redesign. This dynamic nature allows the schema to grow and adapt while maintaining a manageable structure through incremental updates rather than comprehensive changes.
Data Source
AI summary
The disclosure is related to determining an association among Internet of Things (IoT) devices. A first IoT device receives an identifier of a second IoT device, obtains a schema of the second IoT device based on the identifier of the second IoT device, and determines whether or not there is an association between the first IoT device and the second IoT device based on a schema of the first IoT device and the schema of the second IoT device, where the schema of the first IoT device comprises schema elements and corresponding values of the first IoT device and the schema of the second IoT device comprises schema elements and corresponding values of the second IoT device.
