IoT Terminal Access Control via Intermediate Device Capability Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT terminals often experience unreliable connections when accessing IoT platforms through intermediate devices due to insufficient power, traffic, signal strength, distance, storage space, processing capability, or signal transmission issues, leading to communication interruptions and increased power consumption.
Innovation Solution
The method involves acquiring feature information of the IoT terminal or intermediate device and determining whether it satisfies preset conditions, allowing the IoT terminal to selectively access the IoT platform through the intermediate device to avoid communication problems, thereby improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the IoT terminal accesses the IoT platform through the intermediate device, then the coverage and flexibility of the system are improved, but the connection reliability deteriorates due to insufficient power, traffic, signal strength, or other capabilities of the intermediate device
Solution Approach 1:
The patent applies preliminary action by evaluating the capabilities of the intermediate device before establishing a connection. The IoT terminal or intermediate device assesses parameters such as power amount, traffic, signal strength, and processing capability in advance. Based on this preliminary evaluation, the system determines whether the intermediate device is suitable for relaying connections, thereby preventing connection failures before they occur and improving overall connection reliability while maintaining system flexibility.
2Adaptability or versatility
If the IoT terminal always accesses the IoT platform through the intermediate device, then the system flexibility is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamics by making the access path selection adaptive rather than static. The system dynamically adjusts the connection strategy based on real-time capability assessments of the IoT terminal and intermediate device. When the intermediate device has sufficient capabilities, the IoT terminal accesses through it for flexibility; when capabilities are insufficient, the system switches to direct access to reduce power consumption, thereby optimizing energy efficiency while maintaining system flexibility.
3Adaptability or versatility
If the intermediate device is used for connection relay, then the system coverage is improved, but communication interruptions occur due to insufficient capabilities
Solution Approach 1:
The patent applies feedback by implementing a capability assessment mechanism that provides information about the intermediate device's power, traffic, signal strength, and processing capability. This feedback loop enables the system to make informed decisions about connection routing. When the assessment indicates insufficient capabilities, the system adjusts the connection strategy to avoid using that intermediate device, thereby preventing communication interruptions and improving connection stability while maintaining broad system coverage.
