Wireless Terminal Dynamic Route Control for IoT Delay and Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies for IoT services struggle to maintain stable data communication with low delay, as they rely on historical data and statistical parameters, which are not adaptive to rapid changes in communication quality, leading to increased communication costs and delays.
Innovation Solution
A wireless communication terminal that dynamically controls the number of wireless communication systems used for data transmission based on real-time communication quality determination, using a transmission buffer to assess communication quality and adjust the number of routes for data transmission, thereby reducing delay and communication costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If multi-root communication always uses a plurality of different telecommunication carriers simultaneously, then communication delay is reduced, but communication cost increases
Solution Approach 1:
The patent dynamically adjusts the number of wireless communication systems used for data transmission based on real-time communication quality assessment. The determination module evaluates communication quality by comparing transmission buffer amounts against thresholds, and the selection module adaptively controls how many routes to use, transitioning between single-route and multi-route communication modes as conditions change
Solution Approach 2:
The system changes the parameter of the number of communication routes based on communication quality parameters. When communication quality deteriorates (buffer amount exceeds threshold), the system increases the number of routes from one to multiple, and when quality improves, it reduces back to single-route communication
2Stability of the object's composition
If historical data and statistical parameters are used for communication system selection, then system stability is improved, but adaptability to rapid changes in communication quality deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the determination module continuously monitors transmission buffer amounts in real-time and provides this information to the selection module. This closed-loop feedback enables the system to respond immediately to changes in communication quality without relying on historical data, achieving both stability through consistent monitoring and adaptability through real-time response
Solution Approach 2:
The system performs preliminary assessment of communication quality by monitoring transmission buffer amounts before making route selection decisions. By proactively evaluating buffer status and predicting communication quality trends, the system can prepare and switch routes in advance, maintaining stability while adapting to changes
