IoT Device Location Tracking Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IoT devices using LTE or LTE-Advanced communication schemes experience increased power consumption due to unnecessary power usage when providing location tracking functions, especially in low power wide-area communication networks like NB-IoT, even when there is no change in the device's location over time.
Innovation Solution
An electronic device with a communication module, processor, and memory that receives location information requests, determines if the device has moved, and only transmits location information if there is a change, thereby reducing power consumption by skipping responses and monitoring when no change is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the IoT device transmits location information in response to every location information request, then the location tracking function is accurately provided, but power consumption increases
Solution Approach 1:
The patent applies the skipping principle by allowing the IoT device to skip transmitting location information when the location has not changed. The device compares the received location information request with stored location data, and only transmits when there is a change, thereby skipping unnecessary transmissions and reducing power consumption while maintaining tracking accuracy.
Solution Approach 2:
The patent implements partial action by selectively responding to location information requests based on whether the location has actually changed. Instead of responding to every request (excessive action), the device performs partial responses only when necessary, reducing energy consumption while maintaining the essential location tracking function.
2Speed
If the IoT device monitors location information requests continuously, then location tracking responsiveness is improved, but power consumption increases
Solution Approach 1:
The patent applies periodic action by having the device monitor location information requests at specific intervals or under specific conditions rather than continuously. The device checks for location changes periodically and only activates monitoring and transmission functions when a change is detected, reducing power consumption while maintaining responsive tracking.
3Loss of information
If the IoT device transmits location information frequently, then up-to-date location data is provided, but unnecessary data transmission occurs when location is unchanged
Solution Approach 1:
The patent implements feedback by comparing incoming location information requests with previously stored location data. The device uses this feedback mechanism to determine whether the location has actually changed before transmitting new information, ensuring that only updated location data is transmitted and avoiding energy waste from redundant transmissions.
