Solution Overview

Problem

Wireless communication systems face inefficiencies in power usage when employing drone base stations, particularly in managing communication with IoT devices that report data infrequently, leading to suboptimal power consumption for both wireless communication and mobility.

Innovation Solution

A managing module organizes wireless devices into groups based on their data reporting intervals and determines information to align reporting, allowing for synchronized data transmission, thereby reducing power usage by optimizing the network node's active and idle states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the drone base station continuously monitors and remains ready to receive transmissions from IoT devices, then communication reliability is improved, but power consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic monitoring cycles where the drone base station alternates between active monitoring states and idle states. Instead of continuous monitoring, the system checks for transmissions at regular intervals defined by monitoring cycle parameters, allowing the drone to enter low-power modes between cycles while maintaining the ability to detect and respond to IoT device transmissions reliably

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system performs preliminary actions by pre-configuring monitoring parameters, transmission power levels, and response protocols before actual communication events occur. The drone base station prepares communication resources in advance based on predicted IoT device behavior patterns, reducing the need for continuous high-power operation

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the drone base station adjusts position frequently to maintain optimal coverage, then coverage quality is improved, but mobility power consumption increases

Engineering Contradiction:

Improvecoverage qualityVSAvoidmobility power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic position adjustment where the drone base station modifies its position based on real-time conditions such as IoT device distribution, signal quality metrics, and battery status. Instead of fixed or frequent predetermined movements, the system dynamically determines when and where position changes are necessary, optimizing the trade-off between coverage quality and energy expenditure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies different monitoring and positioning strategies to different spatial zones. The drone base station focuses enhanced monitoring and position adjustment on areas with high-density IoT devices or critical communication needs, while reducing activity in low-priority zones, thereby improving overall coverage efficiency without uniform high power consumption

Inventive Principle:

Principle #3Local quality

3Loss of energy

If the monitoring cycle duration is extended to save power, then power efficiency is improved, but response time to transmissions deteriorates

Engineering Contradiction:

Improvepower efficiencyVSAvoidresponse time

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-synchronizing IoT devices to transmit data at predetermined times within the monitoring cycle. This coordination allows the drone base station to enter low-power states knowing exactly when to wake for monitoring, extending the effective monitoring cycle duration while maintaining rapid response capability through anticipatory synchronization

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the drone base station adjusts monitoring cycle parameters based on observed transmission patterns from IoT devices. When transmissions are frequent, the system shortens monitoring cycles; when transmissions are sparse, it extends cycles for power savings. This adaptive feedback loop optimizes the balance between power efficiency and response time based on actual network conditions

Inventive Principle:

Principle #23Feedback
