Radio Node Dispatch Prioritization for Low-Energy Bidirectional Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio nodes face high energy consumption due to data dispatch interruptions when multiple communication modes and protocols are supported, leading to repeated transmissions and inefficient energy use.
Innovation Solution
A method for operating radio nodes that prioritizes data dispatches based on their importance, deferring or postponing less-prioritized transmissions to avoid collisions and reduce energy consumption while maintaining quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio nodes support multiple communication modes and protocols with periodic data dispatch, then the versatility and functionality of the radio node is improved, but energy consumption increases due to interruptions and repeated transmissions
Solution Approach 1:
The patent applies preliminary action by pre-establishing a prioritization scheme for different types of data dispatches before they occur. The control unit is configured to automatically identify and prioritize critical dispatches (such as those in bidirectional communication or time-critical protocols) before scheduling conflicts arise, allowing the radio node to proactively manage energy consumption without compromising communication reliability.
Solution Approach 2:
The patent implements dynamics by making the data dispatch scheduling adaptive and flexible. The control unit dynamically adjusts the execution timing of periodic dispatches based on real-time conditions, such as whether a higher-priority dispatch is already in progress or scheduled. This dynamic scheduling allows the system to maintain versatility while optimizing energy usage by deferring non-critical dispatches when necessary.
2Device complexity
If radio nodes execute periodic data dispatches without prioritization, then the simplicity of the control mechanism is maintained, but energy consumption increases due to interrupted and repeated transmissions
Solution Approach 1:
The patent applies local quality by assigning different priorities to different types of data dispatches based on their specific characteristics. Instead of treating all periodic dispatches uniformly, the control unit identifies local qualities such as bidirectional communication requirements, time-critical protocols, or data types that must be transmitted reliably, and applies appropriate priority levels accordingly. This allows energy optimization without requiring complete redesign of the control mechanism.
Solution Approach 2:
The patent implements self-service by enabling the control unit to autonomously manage prioritization and scheduling without external intervention. The control unit automatically determines which dispatches require higher priority based on pre-configured criteria and independently adjusts the execution timing to prevent interruptions. This self-managing approach maintains relative simplicity while significantly reducing energy loss from repeated transmissions.
3Speed
If the radio node interrupts ongoing dispatches to execute higher-priority dispatches, then the responsiveness to critical communications is improved, but energy consumption increases due to incomplete transmissions requiring repetition
Solution Approach 1:
The patent applies preliminary action by pre-identifying and scheduling higher-priority dispatches before they conflict with ongoing lower-priority transmissions. The control unit looks ahead in the scheduling timeline and reserves time slots for critical communications, ensuring they can execute without interruption. This proactive approach allows the system to respond quickly to critical communications while avoiding the energy waste associated with interrupting and retransmitting incomplete dispatches.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a prioritization controller that mediates between different data dispatches. This intermediary component evaluates the priority levels of incoming dispatches and coordinates their execution timing, allowing critical communications to interrupt lower-priority transmissions in a controlled manner. The intermediary ensures that interruptions only occur when necessary and that all transmissions complete successfully, thereby maintaining energy efficiency while preserving rapid response capability.
Data Source
AI summary
A method operates a bidirectional radio node, in particular a sensor node, preferably a consumption meter, in a network infrastructure. The radio node supports at least one radio technology and is preferably operated with an autonomous energy source, in particular in the form of a long-life battery. The radio node dispatches data in the form of, preferably configurable, data types to at least one receiver, and wherein a periodic dispatch of data, in particular individually definable in its periodicity, is carried out by the radio node. The periodic dispatch of data is carried out by the radio node taking into account a prioritization. The periodic dispatch of the data is interrupted for a higher-priority dispatch of data or for a higher-priority bidirectional communication, whereby periodically provided dispatches are not carried out or are deferred in time.
