IoT Gateway Data Ranking for Narrowband Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices face challenges in prioritizing data transmission over narrowband communication links during broadband failures, as existing systems do not effectively differentiate the criticality of data for various analytics services, leading to inefficient data reporting.
Innovation Solution
An IoT gateway and device system that ranks IoT data based on feedback from analytics servers, assigning an aggregated data ranking to determine the priority of data transmission over narrowband links, ensuring only critical data is reported during broadband failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all IoT data is transmitted over narrowband communication link during broadband failure, then data redundancy and reliability are improved, but bandwidth consumption exceeds available capacity and transmission efficiency deteriorates
Solution Approach 1:
The patent segments IoT data into different priority levels by receiving data rankings from multiple analytics servers and aggregating them to determine an overall data priority. Critical data is separated from non-critical data, allowing selective transmission over the narrowband link during broadband failure, thus resolving the contradiction between transmitting all data for reliability versus only essential data for efficiency
Solution Approach 2:
Instead of transmitting all captured data (excessive action), the system transmits only the critical portion of data determined by aggregated rankings from analytics servers. This partial action approach ensures reliable transmission of essential data while avoiding bandwidth waste on non-critical data during narrowband constraints
2Reliability
If data is transmitted over narrowband link during broadband failure, then backup communication is activated, but the narrowband link lacks sufficient bandwidth to handle all data types
Solution Approach 1:
The patent implements feedback by receiving data rankings from analytics servers that indicate the importance of specific data for their services. The gateway aggregates these rankings and uses the feedback information to determine which data should be transmitted over the narrowband link, enabling intelligent data selection that matches available bandwidth with critical data needs
3Adaptability or versatility
If analytics services receive all IoT data, then comprehensive analytics coverage is achieved, but data processing resources are wasted on non-critical data
Solution Approach 1:
The patent extracts critical data from the complete dataset by receiving data rankings from analytics servers and using aggregated rankings to identify only the essential data that should be transmitted. This extraction approach ensures analytics services receive only necessary data, reducing processing energy consumption while maintaining coverage for critical analytics functions

AI summary
A process of ranking internet-of-things (IoT) data based on IoT analytics services. In operation, the IoT gateway receives IoT data captured by an IoT device and transmits the IoT data to IoT analytics servers each providing a different IoT analytics service. The IoT gateway receives acknowledgments including data rankings from IoT analytics servers. Each of the acknowledgments include a respective one of the data rankings indicating an importance of the IoT data as an input to the IoT analytics service provided by a respective one of the IoT analytics servers. The IoT gateway assigns an aggregated data ranking to the IoT data based on the data rankings included in the acknowledgments received from the IoT analytics servers. The IoT gateway then transmits, to the IoT device, an electronic notification including the aggregated data ranking assigned to the IoT data.
