Bidirectional Radio Node Priority Scheduling for Battery Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio nodes face high energy consumption due to aborted transmissions when multiple communication modes and protocols are supported, leading to incomplete data transmission and increased energy expenditure.
Innovation Solution
A method for operating a radio node that prioritizes transmissions based on energy consumption, transmission frequency, and quality of service, allowing periodic transmissions to be postponed or omitted to ensure priority communications are not interrupted, thereby reducing energy waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modes and protocols are supported by the radio node, then the adaptability and versatility of the radio node are improved, but the energy consumption increases due to transmission aborts and repetitions
Solution Approach 1:
The radio node checks whether a periodic transmission is already in progress before starting a new transmission. This preliminary check prevents transmission conflicts and aborts before they occur, ensuring that multiple communication modes can operate without excessive energy waste from repeated transmissions.
Solution Approach 2:
The transmission scheduling is made dynamic by continuously monitoring the status of periodic transmissions and adjusting the timing of new transmissions accordingly. This dynamic adaptation allows the radio node to handle multiple communication protocols efficiently while minimizing energy consumption from transmission conflicts.
2Productivity
If a periodic transmission is aborted to allow another transmission to proceed, then the productivity and responsiveness of the radio node are improved, but the energy consumption increases due to the need to repeat the aborted transmission
Solution Approach 1:
Before initiating a new transmission, the radio node performs a preliminary check to determine if a periodic transmission is currently in progress. This prevents the abort-schedule-repeat cycle by avoiding transmission conflicts in the first place, thereby eliminating wasted energy while maintaining responsive communication.
Solution Approach 2:
The radio node implements a feedback mechanism that monitors the status of ongoing periodic transmissions and uses this information to adjust the scheduling of new transmissions. This feedback loop ensures that transmissions are coordinated to avoid conflicts, maintaining productivity while preventing energy waste from aborted and repeated transmissions.
3Loss of energy
If transmissions are coordinated to prevent aborts, then the energy efficiency is improved, but the device complexity increases due to the need for transmission coordination mechanisms
Solution Approach 1:
The coordination mechanism is simplified by performing a single preliminary check before each transmission to see if a periodic transmission is in progress. This simple check-based approach achieves energy efficiency without requiring complex coordination protocols, maintaining low device complexity while preventing transmission aborts.
