1Measurement precision

If power analysers are used to measure energy required for data communication, then measurement precision is improved, but device complexity and cost increase due to bulky hardware requirements

Engineering Contradiction:

Solution Approach 1:

The patent replaces physical power analyser hardware with a machine learning-based software model that runs on the wireless device itself. The energy parameter is calculated using ML algorithms that process cellular parameters (signal strength, noise, interference) and network parameters (data size, transmission time, retransmissions) to estimate energy consumption without requiring external measurement equipment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless device performs its own energy measurement function by using its built-in processor to execute machine learning models. The device self-determines energy parameters needed for transmission decisions without relying on separate measurement instruments, thereby eliminating the need for bulky power analysers while maintaining measurement capability.

Inventive Principle:

Solution Approach 1:

The patent implements dynamic adaptation where the machine learning model is initially trained on general data and then continuously fine-tuned using real-world operational data from the specific environment. The model adapts its parameters over time based on actual transmission outcomes, allowing it to adjust to local conditions without requiring exhaustive pre-training for all possible scenarios.

Inventive Principle:

Solution Approach 2:

The patent performs preliminary training with general data to establish a baseline model, then uses ongoing operational data to progressively refine the model for specific environments. This staged approach allows the system to start functioning immediately with reasonable accuracy while continuously improving adaptability to local conditions without requiring complete pre-training.

Solution Approach 1:

The patent implements a feedback mechanism where the energy parameter determined before transmission is compared with the actual energy consumption measured after transmission. The difference between estimated and actual values is used to update and refine the machine learning model, improving future energy estimates. This closed-loop feedback system maintains fast decision-making while progressively enhancing accuracy.

Inventive Principle:
