Template-Based Device Registration for Compact IoT Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of devices with processing and communication capabilities in IoT environments leads to challenges in efficient machine-to-machine (M2M) communication, particularly in managing device registration with servers, due to the large size of registration messages caused by the increasing number of objects, object instances, and resources, which can overwhelm system capacity.
Innovation Solution
A method involving template-based registration and data reduction techniques, such as compression and hashing, is employed to reduce the size of registration messages by using resource templates and group identifiers, allowing devices to transmit compressed data representative of their object hierarchies, thereby simplifying the registration process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If devices transmit complete object hierarchy data during registration, then registration accuracy and completeness is improved, but message size increases overwhelming system capacity
Solution Approach 1:
The patent segments the device object hierarchy into template-based structured data with hierarchical identifiers (root object, child objects, resources). This segmentation allows the registration message to convey complete device information in an organized, compact format rather than transmitting raw uncompressed data, thereby maintaining registration completeness while reducing message size.
Solution Approach 2:
The patent implements a universal template structure that can represent various device types and object hierarchies through a standardized format. The template-based approach with hierarchical identifiers provides a multi-functional registration mechanism that handles diverse device configurations uniformly, enabling complete registration information to be transmitted efficiently across different device types without increasing message size proportionally.
2Adaptability or versatility
If traditional registration methods are used with increasing device complexity, then device functionality is improved, but system capacity is overwhelmed
Solution Approach 1:
The patent segments device information into a hierarchical template structure with root objects, child objects, and resources identified through systematic identifiers. This segmentation allows complex device functionalities to be represented in an organized manner that scales efficiently, enabling the system to handle increasing device complexity without proportionally increasing processing overhead or message size.
Solution Approach 2:
The patent introduces a hierarchical dimension to device registration by organizing data into nested levels (root object → child objects → resources) with corresponding hierarchical identifiers. This dimensional organization transforms flat, cumbersome registration data into a structured hierarchy that improves system capacity utilization while maintaining full device functionality representation.
3Measurement precision
If full device data is transmitted for registration, then registration accuracy is improved, but computational burden increases
Solution Approach 1:
The patent segments complete device data into a hierarchical template structure with clearly defined root objects, child objects, and resources. This segmentation enables accurate registration by ensuring all device components are systematically captured while reducing computational burden through organized data structure that facilitates efficient processing and storage compared to unstructured full data transmission.
