Engineering Contradiction Analysis
1Reliability
If conventional channel selection algorithms are used, then device complexity is reduced, but wireless network performance and reliability deteriorate in real-world environments
Solution Approach 1:
A testbed system is introduced as an intermediary between the wireless device and the machine learning model training process. The testbed simulates real-world wireless environments and device behavior, allowing the model to be trained on realistic data without requiring the actual device to operate in complex conditions. This mediator enables the device to benefit from sophisticated AI-based channel selection while maintaining relatively simple on-device implementation.
Solution Approach 2:
The machine learning model is trained in advance using historical wireless data collected from the testbed system. By performing the complex training operation beforehand, the model learns optimal channel selection strategies for various wireless conditions. The pre-trained model can then be deployed to the wireless device, which only needs to execute the trained algorithm rather than perform complex real-time training, thus improving reliability without excessive on-device complexity.
2Measurement precision
If a testbed system is used to simulate device performance, then machine learning model training accuracy is improved, but system complexity and resource requirements increase
Solution Approach 1:
The testbed system creates a simplified copy or simulation of the actual wireless device and its operating environment. Instead of requiring the real device to be present during training, the testbed generates synthetic data that replicates real-world wireless conditions. This copying approach enables accurate model training with controlled complexity, as the testbed can simulate various scenarios without the full complexity of actual hardware deployment.
3Adaptability or versatility
If machine learning models are trained with multiple datasets, then channel selection adaptability is improved, but data collection time and processing resources increase
Solution Approach 1:
Multiple datasets are collected and the machine learning model is trained in advance using diverse wireless conditions and scenarios. By performing this comprehensive training operation beforehand, the model learns to adapt to various channel conditions, device types, and environmental factors. Once trained, the model can be deployed to wireless devices that immediately benefit from its adaptability without requiring extensive real-time data collection, thus reducing the time loss for individual devices while maintaining high adaptability.
