Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT devices face challenges in reducing power consumption and network traffic while maintaining efficient and precise data reporting, particularly in scenarios where multiple sensor devices share the same space, leading to increased energy usage and bandwidth consumption.
Innovation Solution
A coordinator electronic device forms scheduling groups of sensor devices based on their data, optimizing reporting frequencies and entering power-saving modes to minimize unnecessary data transmission and sensing, thereby reducing power consumption and network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor devices continuously report data to ensure reliable data collection, then data reporting reliability is improved, but power consumption and network traffic increase
Solution Approach 1:
The patent implements periodic reporting intervals where sensor devices transmit data at scheduled times rather than continuously. The coordinator device manages these periodic reporting cycles, allowing sensor devices to enter low-power states between transmissions while ensuring reliable data collection at appropriate intervals.
Solution Approach 2:
Sensor devices autonomously determine their reporting schedules based on configuration parameters received from the coordinator. Each sensor device self-manages its power consumption by independently controlling when to wake up, sense data, and transmit, without requiring continuous coordination or monitoring from the coordinator device.
2Loss of information
If multiple sensor devices report data frequently to ensure comprehensive monitoring, then data collection completeness is improved, but network traffic increases
Solution Approach 1:
The patent divides sensor devices into multiple scheduling groups managed by different coordinator devices. This segmentation allows the network to distribute and manage traffic more efficiently, with each coordinator handling a subset of sensors. The system can selectively activate specific groups based on monitoring needs, reducing overall network traffic while maintaining comprehensive coverage.
3Device complexity
If sensor devices operate autonomously to reduce coordination overhead, then device complexity is reduced, but scheduling efficiency decreases
Solution Approach 1:
The coordinator device serves as an intermediary between the network management system and sensor devices. It receives configuration parameters from higher-level systems and translates them into actionable scheduling instructions for sensor devices. This intermediary role simplifies the architecture by centralizing coordination logic while allowing sensor devices to operate autonomously based on received parameters.
